AB  - Purpose The grey-bluish discoloration of gingiva (known as "amalgam tattoo") does not appear only in the presence of amalgam restorations. It may also be seen in cases of teeth restored with cast dowels and porcelain-fused-to-metal (PFM) restorations. The aim of this article was to determine the clinical characteristics of abutment teeth with gingival discoloration. Materials and Methods This research was conducted on 25 patients referred for cast dowel and PFM restorations. These restorations were manufactured from Ni-Cr alloys. Ninety days after cementing the fixed prosthodontic restorations, the abutment teeth (n = 61) were divided into a group with gingival discoloration (GD) (n = 25) and without gingival discoloration (NGD) (n = 36). The control group (CG) comprised the contralateral teeth (n = 61). Plaque index, gingival index, clinical attachment level, and probing depth were assessed before fabrication and also 90 days after cementation of the PFM restorations. Results The gingival index, clinical attachment level, and probing depths of the abutment teeth that had GD were statistically higher before restoration, in comparison with the abutment teeth in the NGD and control groups. Ninety days after cementation, the abutment teeth with GD had significantly lower gingival indexes and probing depths, compared to the abutment teeth in the NGD group. Both abutment teeth groups (GD and NGD) had significantly higher values of clinical attachment levels when compared to the control group. There were no statistically significant differences in plaque index values between the study groups. Conclusions The results of this study indicated that impairment of periodontal status of abutment teeth seemed to be related to the presence of gingival discolorations. Therefore, fabrication of fixed prosthodontic restorations requires careful planning and abutment teeth preparation to minimize the occurrence of gingival discolorations. Clinical relevance: With careful preparation of abutment teeth for cast dowels and crown restorations it may be possible to decrease the frequency of gingival discolorations adjacent to abutment teeth.

AB  - Introduction: The outcome of periapical surgery has been directly improved with the introduction of novel material formulations. The aim of the study was to compare the retrograde obturation quality of the following materials: calcium silicate (Biodentine; Septodont, Saint-Maur-des-Fosses, France), mineral trioxide aggregate (MTA+; Cerkamed Company, Stalowa Wola, Poland), and glass ionomer cement (Fuji IX; GC Corporation, Tokyo, Japan). Methods: Materials' wettability was calculated concerning the contact angles of the cements measured using a glycerol drop. Cements' porosity was determined using mercury intrusion porosimetry and micro computed tomographic (mu CT) imaging. Extracted upper human incisors were retrofilled, and mu CT analysis was applied to calculate the volume of the gap between the retrograde filling material and root canal dentin. Experiments were performed before and after soaking the materials in simulated body fluid (SBF). Results: No statistically significant differences were found among the contact angles of the studied materials after being soaked in SBF. The material with the lowest nanoporosity (Fuji IX: 2.99% and 4.17% before and after SBF, respectively) showed the highest values of microporosity (4.2% and 3.1% before and after SBF, respectively). Biodentine had the lowest value of microporosity (1.2% and 0.8% before and after SBF, respectively) and the lowest value of microgap to the root canal wall ([10 +/- 30] x 10(-3) mm(3)). Conclusions: Biodentine and MTA possess certain advantages over Fuji IX for hermetic obturation of retrograde root canals. Biodentine shows a tendency toward the lowest marginal gap at the cement-to-dentin interface.

AB  - D Background: The purpose of this study was to ascertain a specific occlusal scheme to reduce temporomandibular disorder signs and symptoms in the therapy of partially edentulous patients with removable partial acrylic dentures. Methodology: Thirty-four partially edentulous patients who had unilateral free-end saddle in the mandible along with a history of TMD signs and symptoms were prosthodontically treated, fitting them with new removable acrylic partial dentures (NRAPD) for their lower jaws. The new and specific occlusal scheme was established with tendencies to restrict mandibular functional movements partly; this proved somewhat awkward, but had the benefit of allowing continued unrestricted occlusal contacts in grinding and functional movements. RDC-TMD clinical examinations and answers to questionnaires were provided for the old dentures, and nine weeks after delivery of NRAPD. Results: After the NRAPD treatment, the patients' painful symptoms were reduced and their mandibular movements were corrected. Statistically significant changes were obtained for the opening pattern (Pearson Chi(2) = 18.609; P = 0001), the maximum unassisted opening (F = 3.507; P = 0.052), the maximum assisted opening (F = 4.299; P = 0.042), and the corrected position of midline (F = 5.893; P = 0.018) before and after the NRAPD treatment. Additionally, significant changes were seen for questions on changes in facial pain to ability to work (Pearson Chi(2) = 26.921; P = 0.00), jaws click or pop when they open, close, or chew (Pearson Chi(2) = 6.227; P = 0.013), jaws make a grating or grinding noise when they open, close, or chew (Pearson Chi(2) = 9.273; P = 0.002), and bites feel unusual (Pearson Chi(2) = 13.170; P = 0.000). Characteristic pain intensity (F = 19.311; P = 0.000), points for disability score (F = 9.830; P = 0.003), disability points (F = 10.208; P = 0.002), and chronic pain grade (F = 7.961; P = 0.006) were significantly different in terms of the effects of the NRAPD therapy. Conclusion: Specific occlusal scheme in NPARD promoted improvement in the therapy.

AB  - The implementation of intraoral and extraoral computer-aided-design and computer-aided-manufacturing (CAD/CAM) systems in prosthetic dentistry has simplified the procedure, shortened the period of design and manufacture and improved accuracy and aesthetic properties of dental restorations. Three-dimensional (3D) digitisation has become an adequate replacement for conventional dental impressions. The market offers a variety of diverse optical intraoral and extraoral CAD/CAM systems equipped with digitisation devices that are based on different working principles. The main goal of this research is to determine whether precision and accuracy differ among optical digitisation devices. The research includes five high-end devices: Cerec AC, Cerec InEos, Trios, KaVo Everest and Sinergia Scan. The evaluation methodology of the experiment is based on CAD inspection. The results, obtained from accuracy and precision measurements with tolerance levels of 0.01, 0.25 and 0.05 mm, indicate that there is a difference in accuracy and precision between optical digitisation devices based on different working principles.

AB  - Background/Aim. Functionally stable occlusion is characterized by optimal and orthopedic stable position of the condyle, harmonious contact ratio of upper and lower teeth in the final occlusal position of the mandible, optimal relationship of dental arches at the eccentric movement of the lower jaw and stable interocclusal space in physiological position. As there are no ideal order of teeth and absolute intermaxilar harmony nor individually acceptable standards or prototype of functionally optimal occlusion, the aim of this study was to analyze occlusal characteristics of identical twins. Methods. This clinical-epidemiological and functional study involved 30 pairs of identical twins, both males and females, aged 20 to 40 years. The main criterion for the selection of participants was preserved function of orofacial system, as a precondition for application of the Peer Assessment Rating (PAR) index, which is the most reliable tool for diagnosing malocclusion and evaluating occlusal parameters: the distance between the contact points of agonists of front segments of the dental arches, side occlusion of the sagittal, vertical and transversal position, overjet, anterior crossbite, deep and open bite, overbite of incisors and relationship of middle dental arches. Results. Using t-test for independent samples, no significant difference in the values of PAR index, according to gender, was established. The average difference of 0.833 between the twin groups (for male twins: ẍ = 7.97, SD = 6.625; for female twins: ẍ = 7.13, SD = 5.606) was not statistically significant [t (58) = 0.526; p = 0.601; 95% confidence interval: -2.339-4.005]. Conclusion. The lack of significant differences in occlusal PAR index analysis in both the same and different twin groups, implies the dominance of hereditary factors.
AB  - Uvod/Cilj. Funkcionalno stabilnu okluziju karakterišu optimalan i ortopedski stabilan položaj kondila, harmoničan kontaktni odnos gornjih i donjih zuba u završnom okluzionom položaju mandibule, optimalna relacija pri ekscentričnim kretnjama donje vilice i stabilan interokluzioni prostor u po- ložaju fiziološkog mirovanja. Pošto ne postoje idealni poredak zuba i apsolutni međuvilični sklad, kao ni individualno prihvatljivi standardi optimalne okluzije, cilj rada bio je analiza okluzalnih obeležja jednojajčanih blizanaca. Metode. Kliničko-epidemiološkim i funkcionalnim ispitivanjem obuhvaćeno je 30 parova jednojajčanih blizanaca, podjednake polne zastupljenosti, starosti od 20 do 40 godina. Osnovni kriterijum za izbor ispitanika bila je očuvana funkcija orofacijalnog sistema, kao preduslov primene Peer Assessment Rating (PAR) indeksa kojim se najpouzdanije dijagnostikuju malokluzije i ocenjuju okluzalni parametri: rastojanje između kontaktnih tačaka agonista prednjih segmenata zubnih nizova, bočna okluzija u sagitalnom, vertikalnom i transverzalnom položaju, incizalni stepenik, prednji ukršten zagrižaj, dubok i otvoren zagrižaj, vertikalni preklop sekutića i odnos sredina zubnih nizova. Rezultati. Primenom t-testa za nezavisne uzorke nije utvrđena statistički značajna razlika u vrednostima PAR indeksa u zavisnosti od pola. Prosečna razlika od 0,833 između blizanačkih grupa (za blizance muškog pola: ẍ = 7,97, SD = 6,625; za blizance ženskog pola: ẍ = 7,13, SD = 5,606) nije bila statistički značajna [t (58) = 0,526, p = 0,601; 95% interval poverenja -2,339-4,005]. Zaključak. Izostanak značajnih razlika pri okluzalnoj analizi PAR indeksa, kod istih i različitih blizanačkih grupa, tumači se dominacijom naslednih faktora.

abstract = "Background/Aim. Functionally stable occlusion is characterized by optimal and orthopedic stable position of the condyle, harmonious contact ratio of upper and lower teeth in the final occlusal position of the mandible, optimal relationship of dental arches at the eccentric movement of the lower jaw and stable interocclusal space in physiological position. As there are no ideal order of teeth and absolute intermaxilar harmony nor individually acceptable standards or prototype of functionally optimal occlusion, the aim of this study was to analyze occlusal characteristics of identical twins. Methods. This clinical-epidemiological and functional study involved 30 pairs of identical twins, both males and females, aged 20 to 40 years. The main criterion for the selection of participants was preserved function of orofacial system, as a precondition for application of the Peer Assessment Rating (PAR) index, which is the most reliable tool for diagnosing malocclusion and evaluating occlusal parameters: the distance between the contact points of agonists of front segments of the dental arches, side occlusion of the sagittal, vertical and transversal position, overjet, anterior crossbite, deep and open bite, overbite of incisors and relationship of middle dental arches. Results. Using t-test for independent samples, no significant difference in the values of PAR index, according to gender, was established. The average difference of 0.833 between the twin groups (for male twins: ẍ = 7.97, SD = 6.625; for female twins: ẍ = 7.13, SD = 5.606) was not statistically significant [t (58) = 0.526; p = 0.601; 95% confidence interval: -2.339-4.005]. Conclusion. The lack of significant differences in occlusal PAR index analysis in both the same and different twin groups, implies the dominance of hereditary factors., Uvod/Cilj. Funkcionalno stabilnu okluziju karakterišu optimalan i ortopedski stabilan položaj kondila, harmoničan kontaktni odnos gornjih i donjih zuba u završnom okluzionom položaju mandibule, optimalna relacija pri ekscentričnim kretnjama donje vilice i stabilan interokluzioni prostor u po- ložaju fiziološkog mirovanja. Pošto ne postoje idealni poredak zuba i apsolutni međuvilični sklad, kao ni individualno prihvatljivi standardi optimalne okluzije, cilj rada bio je analiza okluzalnih obeležja jednojajčanih blizanaca. Metode. Kliničko-epidemiološkim i funkcionalnim ispitivanjem obuhvaćeno je 30 parova jednojajčanih blizanaca, podjednake polne zastupljenosti, starosti od 20 do 40 godina. Osnovni kriterijum za izbor ispitanika bila je očuvana funkcija orofacijalnog sistema, kao preduslov primene Peer Assessment Rating (PAR) indeksa kojim se najpouzdanije dijagnostikuju malokluzije i ocenjuju okluzalni parametri: rastojanje između kontaktnih tačaka agonista prednjih segmenata zubnih nizova, bočna okluzija u sagitalnom, vertikalnom i transverzalnom položaju, incizalni stepenik, prednji ukršten zagrižaj, dubok i otvoren zagrižaj, vertikalni preklop sekutića i odnos sredina zubnih nizova. Rezultati. Primenom t-testa za nezavisne uzorke nije utvrđena statistički značajna razlika u vrednostima PAR indeksa u zavisnosti od pola. Prosečna razlika od 0,833 između blizanačkih grupa (za blizance muškog pola: ẍ = 7,97, SD = 6,625; za blizance ženskog pola: ẍ = 7,13, SD = 5,606) nije bila statistički značajna [t (58) = 0,526, p = 0,601; 95% interval poverenja -2,339-4,005]. Zaključak. Izostanak značajnih razlika pri okluzalnoj analizi PAR indeksa, kod istih i različitih blizanačkih grupa, tumači se dominacijom naslednih faktora.",

AB  - Objective. The aim of this study was to determine the prevalence of craniomandibular disorders (CMD) and occlusal disharmony in identical twins. Methods. Craniomandibular and occlusal disharmony, in a population of 30 pairs of identical twins, aged 20-40 years, with the same gender, were determined by history and functional analysis. The final evaluation was performed using estimation of dysfunction index (Di) and occlusal index (Oi). Results. In study sample 23 twins (38.3%) had a sign of craniomandibular dysfunction, and 33 (55%) of twins had occlusal abnormalities, such as incompatibility of mid dental arches with intercuspal relation -ICP, lack of contact with the antagonists in the ICP, the presence of occlusal interference or loss of teeth. The analysis of the representation of certain craniomandibular signs in 23 patients in whom the index dysfunction (Di) by Helkimo was greater than zero revailed the prevailing disturbed kinetics of the mandible (44.0%), the sound in the TMJ with movements of the mandible (22.0%) and deviation when opening the mouth (22.0%). Positive occlusal index was in 33 (55%) patients, of whom 24 (40%) had mild occlusal disharmony (Oi I = 1), and 9 (15%) patients had the pronounced occlusal discrepancies (Oi II = 2). Conclusion. The comparative analysis of craniomandibular disorders and occlusal status, in identical twins, has shown that occlusal factors play an important role in the etiology of craniomandibular dysfunction.

Analizom zastupljenosti pojedinih kraniomandibularnih znakova, kod 23 ispitanika kod kojih je indeks disfunkcije (Di) po Helkimu veći od nule, preovlađuju poremećena kinetika donje vilice (44.0%), zvuk u TMZ, pri pokretima mandibule (22.0%) i devijacija pri otvaranju usta (22.0%). Pozitivan okluzalni indeks ima 33 (55%) ispitanika, od kojih 24 (40%) sa blagim okluzalnim disharmonijama (Oi I=1), a 9 (15%) ispitanika se izdvaja, po izrazitim okluzalnim diskrepancama (Oi II=2). Zaključak. Uporednom analizom kraniomandibularnih poremećaja i okluzalnog statusa, kod identičnih blizanaca, dokazano je da okluzalni faktori imaju značajnu ulogu u etiologiji kraniomandibularnih disfunkcija.

AB  - Background: Free radicals (FR) occur in oral cavity where lot of food was transferred to through entire life under specific saliva conditions. Many enzymes, microorganism, alcohol beverages, nicotine and other harmful or indifferent substances when in contact to oral tissues might provoke oxidation process under specific condition creating FR's. The similar role might have various dental materials. Aim of the study was to record the level of antioxidant (AO) activity of several permanent (P) luting cements alone or combined with quercetin AO substance. Materials/Methods: P cements were Zn-phosphate, Zn-polycarboxilate, GIC and composite resin cement. They were prepared as original prescription and their variant by 1% weight addition of quercetin. AO activity of cements was measured by HPMC test evaluated by Student t test. Results: There were statistically significant differences among Zn-phosphate, Zn-polycarboxilate and resin dental cements (p > 0,05). GIC displayed significantly higher AO values (p  lt  0,01) versus other three cements. There were no difference in AO capacity between sample of original P cements and their corresponding quercetin variants (p > 0,05). Conclusions: Conventional GIC displayed the most powerful AO activity among P luting cements. Addition of 1% antioxidant quercetin did not improve AO capacity of investigated cements.

AB  - Introduction: In 1974 Marti Helkimo designed special questionnaires which were used for entering adequate contemporary data collected by medical history, analyzing the functions of the orofacial system and analyzing occlusion. Data were evaluated numerically with 0, 1 or 5, depending on the severity of the relevant findings and severity of clinical signs or symptoms of dysfunction. Objective: The aim of the research was to establish and evaluate specially designed Helkimos anamnestic and dysfunction index in monozygotic twins. Materials and Methods: A longitudinal prospective study was carried out on a randomized sample of 30 pairs of twins, 20 to 40 years old, and of both sexes. Dedicated design of the questionnaire made it possible to calculate the Helkimos anamnestic index (Ai), based on subjective feeling and positive or negative answers of subjects about the state of their masticatory apparatus. The clinical dysfunction index (Di) represents objective functional analysis of structural and functional disorders of the orofacial complex, because it monitors multiple parameters. Kinematics of the lower jaw, conditions and limited function of the temporomandibular joints, the presence or absence of painful sensations during mandible movements during palpation of the joints and masticatory muscles, and the overall quantification of the incidence of craniomandibular dysfunction were all monitored and evaluated. The study was conducted in accordance with the local and international laws and ethical standards. Results: Medical records of 47 (78.3%) twins did not present the signs and symptoms of craniomandibular dysfunction, i.e., Ai = 0. Twelve respondents were aware of the existence of mild signs of craniomandibular disorders (CMD). Acute and expressed craniomandibular disorder was identified in one of the twins Ai II 1 (1.7%). By evaluating and analyzing the results obtained using Helkimo analysis, positive dysfunction index (Di> 0), or certain signs and symptoms of impaired function of TMJ were established in 23 twins (38.3%), while the index dysfunction equal to 0 (dI = 0) was found in 37 (61.7%) twins. Spearman's correlation (0.728) demonstrates there is a coefficient of interdependence and mutual association between anamnestic index (Ai) and the dysfunction index (Di), with statistic significance at 1% (p = 0.000). Conclusion: This comparative statistical analysis showed there is a correlation between anamnestic index (Ai) and clinical dysfunction index (Di) by Helkimo et al.
AB  - Uvod: Marti Helkimo je 1974. godine dizajnirao posebne upitnike za unošenje adekvatnih podataka dobijenih anamnezom, analizom funkcija orofacijalnog sistema i analizom okluzije. Podaci se vrednuju numerički sa 0, 1 ili 5, u zavisnosti od odgovarajuće izraženosti nalaza i težine kliničkog znaka, odnosno simptoma disfunkcije. Cilj: Cilj oralno-epidemiološkog i funkcionalnog ispitivanja je utvrđivanje i vrednovanje specijalno dizajniranog anamnestičkog indeksa i indeksa disfunkcije po Helkimu kod jednojačanih blizanaca. Materijal i metode: Longitudinalno prospektivno ispitivanje izvršeno je na randomizovanom uzorku od 30 parova jednojajčanih blizanaca, podjednake polne zastupljenosti i hronološkog uzrasta od 20 do 40 godina. Namenski istraživački dizajn kliničkog upitnika omogućio je izračunavanje anamnestičkog indeksa (Ai) po Helkimu, na osnovu subjektivnog osećaja i pozitivnih ili negativnih odgovora ispitanika o stanju njihovog mastikatornog aparata. Klinički indeks disfunkcije (Di) predstavlja objektivnu funkcionalnu analizu strukturnih i funkcionalnih poremećaja orofacijalnog kompleksa, zahvaljujući zbiru parametara dobijenih vrednovanjem kinematike donje vilice, stanja i limitirane funkcije temporomandibularnih zglobova, prisustva ili odsustva bolnih senzacija pri kretnjama mandibule, tokom palpacije donjoviličnih zglobova i mastikatornih mišića, odnosno sveukupnoj kvantifikaciji učestalosti kraniomandibularnih disfunkcija. Istraživanja su sprovedena u skladu s lokalnim i međunarodnim pravima i etičkim normama. Rezultati: U anamnezi 47 (78,3%) blizanaca ne navodi znake i simptome kraniomandibularnih disfunkcija, odnosno ima Ai=0. Subjektivno svesni postojanja blagih znakova kraniomandibularnih disfunkcija (KMD) bilo je 12 ispitanika, a akutni, izraziti kraniomandibularni poremećaji identifikovani su kod jednog blizanca Ai II 1 (1,7% ). Vrednovanjem i analizom rezultata dobijenih kliničkom funkcionalnom analizom po Helkimu, pozitivni indeks disfunkcije (Di >0), odnosno određeni znaci i simptomi poremećene funkcije TMZ ,utvrđeni su kod 23 jednojajčana blizanca (38,3%), dok je indeks disfunkcije jednak 0 (Di=0) registrovan kod 37 (61,7%) blizanaca, koji nemaju kraniomandibularne poremećaje (KMD). Spiarmanova korelacija (0,728) dokazuje da postoji koeficijent međuzavisnosti, odnosno obostrane povezanosti anamnestičkog indeksa ( Ai) i indeksa disfunkcije (Di) statistički značajan na nivou 1% (p=0,000). Zaključak: Ova komparativna statistička analiza pokazala je da postoji uzajamna povezanost anamnestičkog indeksa (Ai) i kliničkog indeksa disfunkcije (Di) po Helkimu.

Results: Medical records of 47 (78.3%) twins did not present the signs and symptoms of craniomandibular dysfunction, i.e., Ai = 0. Twelve respondents were aware of the existence of mild signs of craniomandibular disorders (CMD). Acute and expressed craniomandibular disorder was identified in one of the twins Ai II 1 (1.7%). By evaluating and analyzing the results obtained using Helkimo analysis, positive dysfunction index (Di> 0), or certain signs and symptoms of impaired function of TMJ were established in 23 twins (38.3%), while the index dysfunction equal to 0 (dI = 0) was found in 37 (61.7%) twins. Spearman's correlation (0.728) demonstrates there is a coefficient of interdependence and mutual association between anamnestic index (Ai) and the dysfunction index (Di), with statistic significance at 1% (p = 0.000). Conclusion: This comparative statistical analysis showed there is a correlation between anamnestic index (Ai) and clinical dysfunction index (Di) by Helkimo et al., Uvod: Marti Helkimo je 1974. godine dizajnirao posebne upitnike za unošenje adekvatnih podataka dobijenih anamnezom, analizom funkcija orofacijalnog sistema i analizom okluzije. Podaci se vrednuju numerički sa 0, 1 ili 5, u zavisnosti od odgovarajuće izraženosti nalaza i težine kliničkog znaka, odnosno simptoma disfunkcije. Cilj: Cilj oralno-epidemiološkog i funkcionalnog ispitivanja je utvrđivanje i vrednovanje specijalno dizajniranog anamnestičkog indeksa i indeksa disfunkcije po Helkimu kod jednojačanih blizanaca. Materijal i metode: Longitudinalno prospektivno ispitivanje izvršeno je na randomizovanom uzorku od 30 parova jednojajčanih blizanaca, podjednake polne zastupljenosti i hronološkog uzrasta od 20 do 40 godina. Namenski istraživački dizajn kliničkog upitnika omogućio je izračunavanje anamnestičkog indeksa (Ai) po Helkimu, na osnovu subjektivnog osećaja i pozitivnih ili negativnih odgovora ispitanika o stanju njihovog mastikatornog aparata. Klinički indeks disfunkcije (Di) predstavlja objektivnu funkcionalnu analizu strukturnih i funkcionalnih poremećaja orofacijalnog kompleksa, zahvaljujući zbiru parametara dobijenih vrednovanjem kinematike donje vilice, stanja i limitirane funkcije temporomandibularnih zglobova, prisustva ili odsustva bolnih senzacija pri kretnjama mandibule, tokom palpacije donjoviličnih zglobova i mastikatornih mišića, odnosno sveukupnoj kvantifikaciji učestalosti kraniomandibularnih disfunkcija. Istraživanja su sprovedena u skladu s lokalnim i međunarodnim pravima i etičkim normama. Rezultati: U anamnezi 47 (78,3%) blizanaca ne navodi znake i simptome kraniomandibularnih disfunkcija, odnosno ima Ai=0. Subjektivno svesni postojanja blagih znakova kraniomandibularnih disfunkcija (KMD) bilo je 12 ispitanika, a akutni, izraziti kraniomandibularni poremećaji identifikovani su kod jednog blizanca Ai II 1 (1,7% ). Vrednovanjem i analizom rezultata dobijenih kliničkom funkcionalnom analizom po Helkimu, pozitivni indeks disfunkcije (Di >0), odnosno određeni znaci i simptomi poremećene funkcije TMZ ,utvrđeni su kod 23 jednojajčana blizanca (38,3%), dok je indeks disfunkcije jednak 0 (Di=0) registrovan kod 37 (61,7%) blizanaca, koji nemaju kraniomandibularne poremećaje (KMD). Spiarmanova korelacija (0,728) dokazuje da postoji koeficijent međuzavisnosti, odnosno obostrane povezanosti anamnestičkog indeksa ( Ai) i indeksa disfunkcije (Di) statistički značajan na nivou 1% (p=0,000). Zaključak: Ova komparativna statistička analiza pokazala je da postoji uzajamna povezanost anamnestičkog indeksa (Ai) i kliničkog indeksa disfunkcije (Di) po Helkimu.",

AB  - Since the beginning of their lives, all living organisms are exposed to the influence of geomagnetic fields. Objectives: With respect to the positive effects that magnetic fields have on human tissues, especially the bactericidal effect, this investigation aimed to assess their influence on the reduction of oral microorganisms. Material and Methods: In order to obtain adequate specimens of dental plaque deposit, microbes such as Streptococcus parasanguinis, Staphylococcus epidermidis, Rhodococcus equi and Candida albicans were isolated from the human mouth. To establish the intensity of microbial growth on the basis of the modified optical density (OD) of agar turbidimetry assay, microbial count and spectrophotometry were applied. The study was carried out with two microbial concentrations (1 and 10 CFU/ml) after periods of incubation of 24 and 48 h and using micromagnets. Results: A positive effect of the magnetic field, resulting in the reduction of dental plaque microbes in vitro, was found. In the first 24 hours of exposure to the magnetic field, the number of all isolated microbes was significantly reduced. The most potent influence of magnets and the most intensified reduction after 24 hours were evident in Candida albicans colonies. The decrease in the influence of magnets on microbes in vitro was also detected. Conclusions: Magnets reduce the number of microbes and might be recommended as a supplement in therapy for reduced periodontal tissues. This is important because periodontal tissues that are in good conditions provide prolonged support to the oral tissues under partial and supradental denture.

AB  - Objective. In our study we have hypothesized that volume changes of amygdala, hippocampus, and prefrontal cortex are more pronounced in male posttraumatic stress disorder participants. Material and Methods. We have conducted a study of 79 male participants who underwent MRI brain scanning. PTSD diagnosis was confirmed in 49 participants. After MRI was taken all scans were software based volume computed and statistically processed. Results. We found that left amygdala is the most significant parameter for distinction between PTSD participants and participants without PTSD. There were no significant differences in volumes of hippocampi and prefrontal cortices. Roc curve method outlined left amygdala AUC = 0.898 (95% CI = 0.830-0.967) and right amygdala AUC = 0.882 (95% CI = 0.810-0.954) in the group of PTSD participants which makes both variables highly statistically significant. Conclusion. The present investigation revealed significant volume decrease of left amygdala in PTSD patients. Concerning important functions of the amygdala and her neuroanatomical connections with other brain structures, we need to increase number of participants to clarify the correlation between impared amygdala and possible other different brain structures in participants with PTSD.

AB  - Introduction. Systemic osteoporosis damages skeletal bones to different degrees. The aim of this study was to determine the intensity and correlation of the osteoporotic changes in the bone density of the skeleton and body mass index (BMI) with a reduction in edentulous mandibles, and to assess possibility of reparation of layers of mandibles with increase of mineral content in jaws of patients affected by osteoporosis. Material and Methods. In this study, 99 edentulous patients with decreased bone density comprised the experimental group, and 48 edentulous patients with normal bone densities formed the control. The age of the examined patients was 69.02 ± 7,9, range 53-74 of females and 69.11 ± 7.1, range 59-76 years. Radiographs of the hands and panoramic radiographs were done for all the patients. The values of BMI, metacarpal index, density of lumbar spine (L2-L4), in the phalanx and in segments of the mandibles as well as the edentulous alveolar ridges heights were measured, assessed and calculated. Results. The lowest value of the total skeletal density was established in the osteoporotic patients on the basis of the average T-score of- 2.5 in men, and - 2.6 in women. Minimum values of the edentulous ridges heights (right/left, in mm) were measured in both osteoporotic females (21.84/22.39) and males 24.90/24.96) patients. By comparison of the densities of the metacarpal bones, proximal phalanx, segments of the edentulous mandibles and based on the numerical values of the edentulous ridges heights, x2 = 3.81 was found in men and x2 = 4.03 was found in women with normal bone densities; x2 = 5.92 was found in men and x2 = 6.25 was found in women with osteopenia; x2 = 2.63 was found in men and x2 = 3.85 was found in women with osteoporosis, on the level of probability of 0.05. After application of calcium and calcitonin in solutions, moderate increment of density (p  lt  0.05; p  lt  0.01) was verified, compensating up to 4% of total loss of mass, minerals and solidity of denture bearing areas of osteoporotic mandibles. Conclusion. Systemic osteoporosis leads to decrease of densities of bones of mandibles and causes reduction of edentulous ridges.
AB  - Uvod. Sistemska osteoporoza oštećuje kosti humanih skeleta u različitoj meri. Cilj ove studije je bio da se utvrde intenzitet i povezanost promena u gustini skeleta usled osteoporoze i indeks telesne mase (BMI) sa redukcijom bezube mandibule, i da se proceni mogućnost reparacije slojeva u mandibuli praćena porastom mineralnog sadržaja u vilicama pacijenata obolelih usled osteoporoze. Materijal i metode. U ovoj studiji, 99 bezubih pacijenata sa smanjenom gustinom kosti su sačinjavali eksperimentalnu grupu, a 48 bezubih pacijenata sa normalnom gustinom kosti su bili kontrolna grupa. Godine starosti ispitanih pacijenata i pacijentkinja su iznosile 69,02 ± 7,9, u granicama od 53 do74 godine kod žena, i 69,11 ±7,1, u granicama od 59 do76 godina kod muškaraca. Radiografije šaka i ortopantomogrami sunačinjeni kod svih ispitanih pacijenata. Vrednosti BMI, metakarpalnih indeksa, gustine tela lumbalnih pršljenova (L2-L4), u falangama i u segmentima donjih vilica, a takođe i visine bezubih alveolarnih grebenova su bile ispitane, izmerene i izračunate. Rezultati. Najmanja vrednost ukupne gustine skeleta je utvrđena kod pacijenata obolelih od osteoporoze na osnovu T veličine od -2,5 kod muškaraca, i -2,6 kod žena. Minimalne vrednosti visina bezubih grebenova (desno/levo, u mm) su bile izmerene i kod žena (21,84/22,39) i kod muškaraca (24,90/24,96) obolelih od osteoporoze. Upoređivanjima gustina metakarpalnih kostiju, proksimalnih falangi, segmenata (prostora) bezubih mandibula, i na osnovu numeričkih vrednosti izmerenih visina bezubih grebenova, x2 = 3,81 je izračunato kod muškaraca, a x2 = 4,03 kod žena sa normalnom koštanom gustinom; x2 = 5.92 je izračunato kod muškaraca, a x2 = 6,25 kod žena sa osteopenijom; x2 = 2,63 je izračunato kod muškaraca, a x2 = 3,85 je izračunato kod žena sa osteoporozom, na osnovu nivoa verovatnoće od 0,05. Posle aplikovanja kalcijuma i kalcitonina u rastvoru, umeren porast gustine (p  lt  0,05; p  lt  0,01) je zabeležen, nadoknađujući, na taj način ukupno do 4% gubitka koštane mase i mineralnog sadržaja u nosećim i potpornim tkivima osteoporoznih donjih vilica. Zaključak. Sistemska osteoporoza dovodi do smanjenja gustine kosti donje vilice i uzrokuje resorpciju bezubih grebenova.

AB  - Background/Aim. It is important that the height of the edentulous alveolar ridge after tooth extraction remains at a reasonable acceptable level for as long as possible. The aim of this study was to report preliminary results of the clinical effect of local oral submucous administration of dexamethasone after tooth extractions in order to prepare alveolar supporting tissues for acceptance of removable dentures. Methods. In a total of 15 patients (11 partially and 4 completely edentulous) the quantity of 0.25 mL to 0.5 mL of dexamethasone was injected bucally and orally in the region of the tooth socket after complicated extractions. Results. Healing of extraction wounds was uneventful in all the patients, without pain or local inflammation. Conclusion. Dexamethasone can be locally applied to oral tissues to prevent post-extraction inflammation and extensive resorption of the residual alveolar ridge. The obtained results are promising for patients undergoing classic prosthodontic rehabilitation soon after tooth extraction, demonstrating that there are no adverse effects after local oral corticosteroids administration.
AB  - Uvod/Cilj. Od ključnog značaja je da visina bezubog alveolarnog grebena posle vađenja zuba ostaje što duže na prihvatljivom nivou. Cilj rada bio je da se prikažu preliminarni rezultati efekata lokalne submukozne primene deksametazona na tkiva iz kojih su ekstrahovani zubi radi pripreme alveolarnih tkiva i nosećih tkiva za prihvatanje zubnih proteza. Metode. Kod ukupno 15 pacijenata (11 krezubih i 4 bezuba) dato je od 0.25 mL do 0.5 mL deksametazona per injectionem bukalno i oralno u alveolarne čašice posle komplikovanih ekstrakcija zuba. Rezultati. Zarastanja rana kod svih pacijenata bila su neometana, bez bolova ili lokalnih upala. Zaključak. Deksametazon može biti lokalno dat u oralna tkiva sa ciljem prevencije postekstrakcione upale i izražene resorpcije rezidualnog alveolarnog grebena. Rezultati studije su obećavajući za lečenje pacijenata koji će biti stomatoprotetski rehabilitovani neposredno posle ekstrakcija zuba i ukazuju na to da nema neželjenih efekata prilikom lokalne primene kortikosteroida na tkiva iz kojih su ekstrahovani zubi.

AB  - Introduction. Complete denture reinforced with metal bases is fabricated in cases of fracture risk as well as in selected patients with neuromuscular disorders. The aim of this report was to present different designs of metal framework for complete denture and their advantages in the treatment of edentulous patients. Material and Methods. The study included 116 edentulous patients who received complete dentures. The respondents were divided into two groups according to the type of denture used. Thirty one patients were rehabilitated with complete dentures reinforced with metal base, whereas 85 patients received conventional complete acrylic dentures. Metal bases were fabricated using Co-Cr-Mo alloy. Two designs different in regards to the vibrating line were fabricated: metal frame extended to the vibrating line and acrylic resin extended to the vibrating line. After investing and casting, metal bases were electropolished. Subsequent processes of arranging artificial teeth, waxing, flasking and finishing completed the fabrication process of dentures. Results. Denture base fractures were prevented in majority of patients. The design of upper denture where metal frame was extended to the vibrating line and metal base with elongation over the convex edentulous ridge in lower jaw were the most favored and successful in prosthetic rehabilitation of experimental group of edentulous patients. There was no need for rebasing of complete dentures reinforced with metal base. Conclusion. Complete denture reinforced with metal base presents a favorable design for rehabilitation of edentulous patients with well pronounced edentulous ridges and low tendency to resorption.
AB  - Uvod. Totalne proteze ojačane metalnim bazama izrađuju se onda kada postoji rizik od lomljenja baze, odnosno kod pacijenata sa neuromišićnim poremećajima. Cilj ovog rada bio je da prikaže različite oblike metalnih baza u izradi totalnih zubnih proteza, kao i prednosti ovakvih proteza u lečenju osoba koje nemaju zube. Materijal i metode rada. Istraživanjem je obuhvaćeno 116 pacijenata bez zuba koji su lečeni totalnim protezama. Ispitanici su svrstani u dve grupe prema vrsti proteze koja je korišćena. Eksperimentalnu grupu činio je 31 pacijent kod kojeg je primenjena totalna proteza ojačana metalnim bazama, dok je kontrolnu grupu činilo 85 pacijenata koji su rehabilitovani konvencionalnim totalnim protezama od akrilata. Totalne proteze ojačane metalnim bazama izrađenim od legure kobalta, hroma i molibdena napravljene su u dva različita oblika u odnosu na liniju vibracije. Kod prvog oblika metal je proširen do linije vibracije, a kod drugog akrilatna masa. Posle ulaganja i livenja obavljeno je elektropoliranje metalne baze. U završnim postupcima postavljeni su veštački zubi, izvršeni su oblikovanje voskom, ulaganje u kivetu i obrada proteza. Rezultati. Prelom baze proteze je sprečen u najvećem broju slučajeva. Oblik sa proširenjem metala do linije vibracije u gornjoj bezuboj vilici i oblik s elongacijom konveksne površine preko bezubog grebena u donjoj vilici bili su najpovoljniji oblici koji su uslovili potpun uspeh u rehabilitaciji pacijenata eksperimentalne grupe. Kod ovih ispitanika nisu zabeleženi slučajevi podlaganja izrađenih totalnih proteza sa bazama ojačanim metalnim skeletima. Zaključak. Totalne proteze u kojima su baze ojačane metalnim skeletima su povoljan oblik proteze u rehabilitaciji osoba bez zuba s vrlo dobro izraženim bezubim grebenovima kod kojih ne postoji sklonost ka resorpciji grebena.

AB  - Various indexes could be used in assessing of reduction of density of bones. However value of each index could indicate, or not to indicate exact changes of systemic skeletal density. Aim of this study was to assess accuracy of representing and correlation of body mass index, lumbar and skeletal density and mandibular density of individuals with minor or moderate reduction of bone densities. Materials and method. 9 men (mean age 62.4 yrs.) and 14 women (mean age 65.1 yrs.) were examined. Body mass index (BMI), density of skeleton (g/cm3) (Lunar DPX-L, USA),and density of mandible using panoramic radiograph (Orthopantomograph 10,Siemens,Germany) and digital densitometer (DT II 05, England) were calculated for every subject. Results. Mean values amounted BMI=17.1 kg/m2, skeletal density T=-1.8, and optical density of a bodies of mandibles ρo= 0.98 U/mm2, for men. Pearson's correlation coefficient was 0.324, and Spearman's coefficient was 0.219. Mean values amounted BMI=15.7 kg/m2, skeletal density T=-2.1, and density of mandibles ρo= 0.63 U/mm2, for women. Pearson's correlation coefficient was 0.201, and Spearman's coefficient was 0.167. Conclusion. BMI, T and ρo indicated small or moderate reduction of skeletal density- osteopenic changes in all subjects. Calculated values of statistical parameters indicated small significance in correlations of indexes of density and mass of bones.

Rezultati. Kod muškaraca su prosečne vrednosti iznosile BMI=17,1 kg/m2, gustine skeleta T=-1.8, i gustine tela kostiju mandibula ρo= 0,98 U/mm2. Vrednost Pirsonovog koeficijenta korelacije je 0.324, a vrednost Spirmanovog koeficijenta je iznosila 0.219.

AB  - Background/Aim. In addition to damage of the bones that support the remaining teeth, degradation of osteoporotic oral bones also lead to a consequent reduction of supporting tissues and the loss of dentures retention. The aim of this study was to assess the clinical and radiographic outcomes following injection of a calcitonin and calcium solution into the buccal aspects of edentulous mandibles. Methods. The experimental group of 67 edentulous patients diagnosed with osteoporosis, and the control group of 19 nonosteoporotic edentulous patients were treated with the calcitonin and calcium once solution per month. Mandibular bone density was measured from panoramic radiographs, supplemented by T scores of skeletal density in the experimental group. Results. After the therapy, measurements showed moderate increases in bone density, compensating for up to 4% of the total loss of minerals and solidity of denture-bearing areas of osteoporotic mandibles. Osteoporosis affected women earlier than men in this study. Conclusion. Application of a calcitonin and calcium solution is a suitable method of preprosthetic therapy for edentulous osteoporotic patients.
AB  - Uvod/Cilj. Degradacija osteoporoznih viličnih kostiju vodi ka oštećenju kostiju koje podržavaju preostale zube, ali i posledičnoj redukciji potpornog tkiva i gubitku retencije proteze. Cilj rada bio je da se procene klinički i radiografski parametri posle tretmana bezubih mandibula rastvorom kalcitonina i kalcijuma ubrizganog u bukalne recesuse. Metode. Ispitnu grupu činilo je 67 bezubih pacijenata sa dijagnostikovanom osteoporozom, a kontrolnu grupu 19 bezubih pacijenata sa normalnom gustinom kosti (bez osteoporoze). Svi ispitanici dobijali su rastvor kalcitonina i kalcijuma jednom mesečno. Gustina kosti mandibule merena je na osnovu ortopantomograma svih ispitivanih pacijenata, uz komplementarni T-nalaz gustine skeleta na sistemskom nivou kod pacijenata iz ispitne grupe. Rezultati. Po završenoj terapiji utvrđen je umeren porast gustine kosti, čime je nadoknađeno oko 4% ukupnog gubitka mineralnih supstanci u regionima nosećeg tkiva osteoporoznih mandibula. Osteoporoza je zahvatala kosti žena ranije od kostiju muškaraca u ovoj studiji. Zaključak. Primena rastvora kalcitonina sa kalcijumom predstavlja kvalitetan metod medikacije i preprotetske pripreme bezubih pacijenata obolelih od osteoporoze.

In addition to damage of the bones that support the remaining teeth, degradation of osteoporotic oral bones also lead to a consequent reduction of supporting tissues and the loss of dentures retention. The aim of this study was to assess the clinical and radiographic outcomes following injection of a calcitonin and calcium solution into the buccal aspects of edentulous mandibles. Methods. The experimental group of 67 edentulous patients diagnosed with osteoporosis, and the control group of 19 nonosteoporotic edentulous patients were treated with the calcitonin and calcium once solution per month. Mandibular bone density was measured from panoramic radiographs, supplemented by T scores of skeletal density in the experimental group. Results. After the therapy, measurements showed moderate increases in bone density, compensating for up to 4% of the total loss of minerals and solidity of denture-bearing areas of osteoporotic mandibles. Osteoporosis affected women earlier than men in this study. Conclusion. Application of a calcitonin and calcium solution is a suitable method of preprosthetic therapy for edentulous osteoporotic patients., Uvod/Cilj. Degradacija osteoporoznih viličnih kostiju vodi ka oštećenju kostiju koje podržavaju preostale zube, ali i posledičnoj redukciji potpornog tkiva i gubitku retencije proteze. Cilj rada bio je da se procene klinički i radiografski parametri posle tretmana bezubih mandibula rastvorom kalcitonina i kalcijuma ubrizganog u bukalne recesuse. Metode. Ispitnu grupu činilo je 67 bezubih pacijenata sa dijagnostikovanom osteoporozom, a kontrolnu grupu 19 bezubih pacijenata sa normalnom gustinom kosti (bez osteoporoze). Svi ispitanici dobijali su rastvor kalcitonina i kalcijuma jednom mesečno. Gustina kosti mandibule merena je na osnovu ortopantomograma svih ispitivanih pacijenata, uz komplementarni T-nalaz gustine skeleta na sistemskom nivou kod pacijenata iz ispitne grupe. Rezultati. Po završenoj terapiji utvrđen je umeren porast gustine kosti, čime je nadoknađeno oko 4% ukupnog gubitka mineralnih supstanci u regionima nosećeg tkiva osteoporoznih mandibula. Osteoporoza je zahvatala kosti žena ranije od kostiju muškaraca u ovoj studiji. Zaključak. Primena rastvora kalcitonina sa kalcijumom predstavlja kvalitetan metod medikacije i preprotetske pripreme bezubih pacijenata obolelih od osteoporoze.",

AB  - Background/Aim. Balanced occlusal arrangement of artificial teeth and balanced occlusion is a specific type of occlusion that preserves the stability of complete dentures. Balanced occlusion comprises realization of tooth contacts at the working side as well as at the balancing side, at the same time. The aim of this study was to assess the influence of balanced occlusal arrangement of artificial teeth on the decrease in reduction of edentulous alveolar ridge. Methods. A longitudinal study on 91 fully edentulous patients was conducted using their panoramic radiographs and parameters of vertical dimension of edentulous ridges. All the patients were clinically examined by the same and a qualified dental practitioner. Numerical values of parameters of vertical dimensions of edentulous ridges and lines were statistically processed and compared using the Student's t-test. Results. Vertical dimensions and heights of edentulous ridges were different after comparison of parameters in complete denture wearers with balanced occlusion and complete denture wearers without bilaterally balanced occlusion, as well as between male and female edentulous patients. Statistically significant differences of heights were established in complete denture wearers' with a set of artificial teeth without balanced occlusion, at the baseline and 12 months after wearing of complete dentures. Conclusion. Balanced occlusion is a favored occlusal design in setting of artificial teeth in conventional complete dentures, which preserves edentulous ridge and influence the stability of dentures.
AB  - Uvod/Cilj. Postava veštačkih zuba po balansnoj okluziji (BO) i balansno okluzalno uravnoteženje je posebna vrsta okluzije koja uslovljava i čuva stabilnost totalnih proteza. Balansna okluzija podrazumeva da kontakti veštačkih zuba postoje u isto vreme i na radnoj i na balansnoj strani. Cilj ove studije bio je da se ispita uticaj postave zuba po balansnoj okluziji na sniženje redukcije bezubog grebena. Metode. U okviru ove longitudinalne studije ispitan je 91 bezubi pacijent uz korišćenje ortopantomograma i parametara vertikalne dimenzije bezubog grebena. Svi pacijenti bili su i klinički ispitani od strane istog kvalifikovanog stomatologa, specijaliste stomatološke protetike. Numeričke vrednosti parametara vertikalne dimenzije bezubih grebenova bile su statistički obrađene i upoređene korišćenjem Studentovog t-testa. Rezultati. Vertikalna rastojanja i visine bezubih grebenova bile su različite pri upoređivanju parametara kod pacijenata koji su koristili totalne proteze sa BO i pacijenata koji su imali totalne proteze bez obostrane BO, a takođe i između pacijenata i pacijentkinja. Statistički značajne razlike utvrđene su kod pacijenata sa totalnim protezama u kojima zubi nisu bili postavljeni u skladu sa obostrano uravnoteženom BO, na početku merenja i posle 12 meseci terapije totalnim protezama. Zaključak. Balansna okluzija je zadovoljavajući i uspešan okluzalni odnos veštačkih zuba u totalnim zubnim protezama koji utiče na očuvanje bezubog grebena i uslovljava stabilnost totalnih proteza.

AB  - Introduction. The aim of this study was to fabricate a complete upper acrylic denture and a partial lower acrylic denture and provide occlusal rehabilitation with added benefit of correcting the position of altered condyle in a dysfunctional stomatognathic system. Case Report. Procedures for fabrication of acrylic dentures are thoroughly described. Specific scheme of occlusion was applied in the treatment of this patent. Occlusal contacts were established as tripod minor contacts on the side where the part of upper edentulous ridge was intensively reduced (on the right side) with divergent tracing of the condyle due to dysfunction. Tripod contacts were established on occlusal surfaces of opposing teeth as well. Contacts on the left side were formed as circumferential surfaces. Specially distributed occlusal contacts favorably influenced reduction of occlusal stresses on supporting tissues in the mouth of the patient. Tooth contacts arranged in such particular order were established to redistribute loading as well as to prevent excessive propulsion and latero-protrusive movements of the lower jaw. Conclusion. Occlusal pattern of tripod and single-point contacts was used to compensate differences in condylar movements of this patient with stomatognathic dysfunction, intending to diminish loads on reduced surfaces.

AB  - Surfaces of edentulous jaw vary in patients with different skeletal classes. The aim of this study was to assess surfaces of supporting tissue areas of edentulous jaws of patients with the skeletal class 2. Materials and method. Thin aluminum phoils (0.5 mm of thickness) were adapted on plaster's surfaces of 47 pairs of edentulous jaw casts. Phoils were positioned to millimetric paper and surface of each foil; was calculated. Additionally, surfaces were measured by plan-meter (G. Coradi, Switzerland, serial no. 49823). The error of measurement was 1%. Skeletal class of edentulous jaws was analyzed on lateral cephalometric radiographs with the analyses of ANB (SNA-SNB) angle. Results. Surfaces of edentulous upper jaws were calculated: 4521 ± 471mm2 for men, and 4386±935 mm2 for women. Surfaces of edentulous lower jaws were 1571 ± 379 mm2 for edentulous men, and 1524 ± 449 mm2 for edentulous women. ANB values were higher than 4o. Dissimilarity of numerical values of surfaces of edentulous upper jaws was 7,2 % when patients with skeletal class I and skeletal class II were compared, but the surfaces of edentulous lower jaws were 16,1 % smaller in patients with skeletal class II. Conclusion. Surfaces of edentulous jaws of men were larger in comparison to women. Edentulous surfaces to the right side were not absolutely symmetric with surfaces to the left side. Patients with skeletal class II had smaller jaws.

AB  - Introduction. If patients have remained only a few teeth in one jaw, these teeth can be retained and specifically prepared to bear mobile supradental prosthesis i.e. overdenture (OD). The patients are usually very motivated to preserve remained teeth. The aim of this study was to present the plan, the preparation procedure and the treatment protocol for the remaining teeth that will bear full mobile OD. Material and Methods. Study included 12 patients and 23 remaining teeth. Treatment plan considered: radiological analysis and selection of the remaining teeth, reduction of the clinical crown of the teeth, endodontic and periodontal treatment and finally conservative or prosthodontic restoration of these teeth. Fifteen teeth were restored using cast crown build-up (cap) and eight teeth were restored with amalgam restorations. Patients who received twelve lower mobile full OD were observed for one year to assess the integrity of the extra alveolar tooth structure. Results. After observation period of one year, the integrity of crown restorations was maintained as well as the alveolar bone height. Conclusion. The restoration of the remaining teeth using cast crown build-up (cap) and amalgam is very important for maintaining extra alveolar tooth structure and successful treatment with overdentures.
AB  - Uvod. Kod pacijenata kod kojih je preostao mali broj zuba u jednom zubnom luku zubi se mogu zadržati u vilici, na poseban način pripremiti, a zatim se preko njih može izraditi mobilna supradentalna proteza (SDP). Kako pacijent zadržava preostale zube, on je obično veoma motivisan za uspeh celokupnog lečenja. Cilj ovog rada je bio da se prikažu plan, priprema i način restauracije preostalih zuba koji treba da čine potporu mobilnih totalnih SDP. Materijal i metode rada. Ispitano je 12 pacijenata sa ukupno 23 preostala zuba. Plan lečenja je obuhvatio: radiološku analizu i selekciju preostalih zuba, redukciju kliničkih krunica zuba koje treba zadržati, endodontsku pripremu i parodontološku obradu zuba i konačno konzervativnu ili protetičku restauraciju ovih zuba. Od preostalih zuba, 15 je pripremljeno livenim kapicama, a osam amalgamskim ispunima. Pacijenti su rehabilitovani izradom 12 donjih totalnih SDP i klinički praćeni godinu dana, kako bi se proverilo očuvanje ekstraalveolarne strukture zuba. Rezultati. Rezultati dobijeni nakon godinu dana pokazali su da nije došlo do destrukcije nijedne krunične restauracije, a pri tom je inicijalna visina alveolarnog grebena bila očuvana. Zaključak. Na osnovu rezultata ovog istraživanja može se zaključiti da je restauracija livenim kapicama i amalgamskim ispunima značajan faktor u očuvanju ekstraalveolarne strukture zuba, a samim tim i validan način za očuvanje potpore SDP.

AB  - Introduction. Calcium phosphates are chemical compounds that can be found in various forms within nature, as well as in human jaws and bones. The aim of this study was to assess the structure of solid chemical compounds which form the structure of normal and osteoporotic jaw-bones. Materials and Methods. The jaw-bones taken from human cadavers were used in the study. Crystalographic forms of calcium phosphate, in the samples of human jaw-bone, were determined using X-ray diffraction technique. The experimental bone samples originated from osteoporotic jaw-bone of cadavers while control samples were taken from dentate jaw-bones of non-osteoporotic cadavers. Results. The results of this study showed that hydroxyapatite was the only phase determined in control non-osteoporotic bone samples. In experimental (osteoporotic) bone samples, the same phase was registered, as well as calcium monophosphate and hydrated calcium phosphate, registered as increments of values on α axis. Conclusion. Hydroxyapatite was the only compound detected in normal bone while osteoporotic bone contained others crystallographic forms of calcium phosphates.

Eksperimentalni uzorci kostiju su izdvojeni iz bezubih osteoporoznih vilica, a kontrolni uzorci iz ozubljenih vilica bez osteoporoze. Rezultati. Dobijeni rezultati su pokazali da je hidroksiapatit jedina kristalna faza u kontrolnim uzorcima vilica. U uzorcima vilica s osteoporozom, pored navedene faze, uočeni su i kalcijum-monofosfat i hidratisani kalcijum-fosfat kod povećanja vrednosti na alfa osi. Zaključak. Kod normalne kosti zastupljen je samo hidroksiapatit, dok se kod kosti zahvaćene osteoporozom javljaju i drugi kristalografski oblici kalcijum-fosfata.

AB  - Introduction. The surface area of edentulous jaw has been considered as an important functional and anthropometric parameter. The aim of this study was to assess the surface area of supporting tissue in edentulous jaws of patients with the skeletal class I. Material and Methods. Thin aluminum foils (0.5 mm of thickness) were adapted on plaster surfaces of 139 pairs of edentulous jaws casts. Foils were positioned on a millimeter-paper in order to measure their areas. Additionally, surface areas were measured using a mechanic plan-meter (G. Coradi, Zurich, Switzerland, serial no. 49823). The measurement error was 1%. Skeletal class of edentulous jaws was determined by analysis of lateral cephalometric radiographs, and assessing the ANB (SNA, SNB) angle. Results. The average surface area of edentulous upper jaws was 4654±407 mm2 in males, and 4212±368 mm2 in females. Edentulous lower jaws had average surface area of 2843±339 mm2 in males, and 2334±295 mm2 in females. Statistically significant difference (p lt 0.001) was found in comparison of surface areas and dimensions of upper and lower edentulous jaws in male and female. ANB values ranged from 2 to 4 degrees. Conclusion. The surface area is an important parameter in the analysis of edentulous jaws. Edentulous jaws in males had greater surface areas and dimensions as compared to females. Edentulous areas on the right side were not absolutely symmetric to areas on the left side.

Uz površine gipsa na 139 parova preliminarnih anatomskih modela bezubih gornjih i donjih vilica adaptirane su aluminijumske folije (debljine 0,5 mm), a zatim postavljene na milimetarsku hartiju radi merenja površina. Sekundarno, zbog provere, površine su izmerene i pomoću mehaničkog planimetra (G. Coradi, Zürich, Switzerland, serial no. 49823). Greška pri merenju je iznosila 1%. Skeletna klasa bezubih vilica je utvrđena na osnovu profilnih telerendgenskih radiograma glave i analize ugla ANB (SNA-SNB). Rezultati. Površine bezubih gornjih vilica su bile 4654±407 mm2 kod muškaraca i 4212±368 mm2 kod žena, a površine bezubih donjih vilica 2843±339 mm2 kod muškaraca i 2334±295 mm2 kod žena. Utvrđena je statistički značajna razlika (p lt 0,001) između površina i veličina donjih i gornjih bezubih vilica. Izmerene vrednosti uglova ANB bile su 2-4 stepena. Zaključak. Površina je važan parametar u analizi i proceni nosećih tkiva bezube vilice. Izmerene površine bezubih gornjih vilica su veće kod muškaraca nego kod žena. Bezube površine na desnoj strani nisu potpuno simetrične bezubim površinama na levoj strani.

AB  - From the very beginning of life, living organisms were exposed to the influence of geoelectric and geomagnetic fields, with established balance with this respect. Development of civilization has been distorted balance and harmony, imposing the extreme need for magnetism. Respecting positive effects of magnetic field to tissues, especially 'bactericide' effect, this investigation was conducted on the aim to assess the influence of magnetic field to oral microbes. Materials and method. This investigation was carried to in vitro. To obtain adequate samples of deposits or specimens of dental plaque, were from certain microbes which were isolated from human mouth. Microbes isolated from samples were Streptococcus parasanguis, Staphylococcus epidermidis, Rodococcus equi and Candida albicans. Turbidimetry array was applied for investigation of this kind. The method of spectrophotometry was applied, to obtain optical den­sity (OD) value and to establish indirectly a growth of intensity of sowed microbe's stains on the basis of modified OD of agar. Investigation was carried on two level of density of microbes of 1 CFU/ml as well as of 10 CFU/ml after 24h period and 48h period of incubation of microbes. Results. Positive effect of magnetic field upon dental plaque of bacteria reduction in vitro was recognized. At the baseline-initial 24 hours period of measurement of exposition to magnetic field, the count of all isolated mi­crobes has been significantly reduced, in the both of agar of increased density as well as of agar with reduced OD. Over the time, the decrement of influence of magnets versus microbes in vitro has been detected. Conclusion. Count of this influence of the magnet to microbes is of extreme importance in parodontology. This way, the positive influence of magnet to supporting tissues and quality and durability of overdenture was confirmed. .
AB  - Sva živa bića su izložena dejstvu geoelektričnog i geomagnetskog polja i u tom smislu je ostvarena ravnoteža. Sa razvojem civilizacije ta ravnoteža se narušava u smislu da slabi uticaj geomagnetnog polja i postoji t.z.v. 'glad' za magnetizmom. Imajući u vidu pozitivan uticaj magneta na sva biološka tkiva, posebno 'baktericidni' efekat israživanje je sprovedeno sa ciljem da se ispita uticaj magnetnog polja na oralnu mikrofloru. Materijal i metod: Istraživanja su sprovedena in vitro. Uzorci, tj. brisevi zubnih naslaga poticali su sa zuba pacijenata Stomatološkog fakulteta u Beogradu. Iz uzoraka su izolovani: Streptococcus parasanguis, Staphylococcus epidermidis, Rodococcus equi i Candida albicans. Korišćena je metoda turbidimetrija gde se spektrofotometrom na osnovu optičke gustine bujona indirektno utvrđuje intenzitet rasta zasejanih mikro-organizama. Ispitivanje je vršeno sa 2 gustine mikroorganizama 1 i 10 CFU/ml i to nakon 24 i 48 h inkubacije mikroorganizama. Rezultati pokazuju da je došlo do redukcije broja bakterija u in vitro uslovima. U prvih 24 h izloženosti uticaju magnetnog polja ta redukcija je bila značajna kako u bujonima veće tako i manje gustine. Tokom vremena uticaj magneta na brojnost mikroflore u in vitro uslovima opada. Zaključak Ovakav uticaj magneta na brojnost mikroorganizama je značajan u parodontologiji pa samim tim ima pozitivan uticaj na potporna tkiva ispod supraden-talnih proteza, na njihov kvalitet i trajnost. .

Positive effect of magnetic field upon dental plaque of bacteria reduction in vitro was recognized. At the baseline-initial 24 hours period of measurement of exposition to magnetic field, the count of all isolated mi­crobes has been significantly reduced, in the both of agar of increased density as well as of agar with reduced OD. Over the time, the decrement of influence of magnets versus microbes in vitro has been detected. Conclusion. Count of this influence of the magnet to microbes is of extreme importance in parodontology. This way, the positive influence of magnet to supporting tissues and quality and durability of overdenture was confirmed. ., Sva živa bića su izložena dejstvu geoelektričnog i geomagnetskog polja i u tom smislu je ostvarena ravnoteža. Sa razvojem civilizacije ta ravnoteža se narušava u smislu da slabi uticaj geomagnetnog polja i postoji t.z.v. 'glad' za magnetizmom. Imajući u vidu pozitivan uticaj magneta na sva biološka tkiva, posebno 'baktericidni' efekat israživanje je sprovedeno sa ciljem da se ispita uticaj magnetnog polja na oralnu mikrofloru. Materijal i metod: Istraživanja su sprovedena in vitro. Uzorci, tj. brisevi zubnih naslaga poticali su sa zuba pacijenata Stomatološkog fakulteta u Beogradu. Iz uzoraka su izolovani: Streptococcus parasanguis, Staphylococcus epidermidis, Rodococcus equi i Candida albicans. Korišćena je metoda turbidimetrija gde se spektrofotometrom na osnovu optičke gustine bujona indirektno utvrđuje intenzitet rasta zasejanih mikro-organizama. Ispitivanje je vršeno sa 2 gustine mikroorganizama 1 i 10 CFU/ml i to nakon 24 i 48 h inkubacije mikroorganizama. Rezultati pokazuju da je došlo do redukcije broja bakterija u in vitro uslovima. U prvih 24 h izloženosti uticaju magnetnog polja ta redukcija je bila značajna kako u bujonima veće tako i manje gustine. Tokom vremena uticaj magneta na brojnost mikroflore u in vitro uslovima opada. Zaključak Ovakav uticaj magneta na brojnost mikroorganizama je značajan u parodontologiji pa samim tim ima pozitivan uticaj na potporna tkiva ispod supraden-talnih proteza, na njihov kvalitet i trajnost. .",

The aim of this study was to determine changes and shape and form of temporo-mandibutar joint surtace of partially edentulous and completely edentulous osteoporotic patients. On the basis of decreased bone density and pan­oramic radiographs of patients, 73 (23 men, aged 61-75 yrs., and 50 women, aged 59-76 yrs.) were selected for this experiment. Panoramic radiographs were provided for each of the patient of the experimental group (Orthopantomograph 10-serial number 01492, Siemens, Germany). In relation to contour of bony surfaces of TMJ, as well as lines assigned, deviations of intercondylar axis and mandibula-basal lines to reference hortzontal and saggital planes, and change of surfaces of temporo-mandibutar joint were assessed. Low values of bone density, reductions of dimension of condylar surface of an one or the both of temporo-mandibul ar joint condyles as well as temporo-mandibular joint surfaces, deviation of position of intercondylar axis and negative remodeling were established. Orofacial dysfunction's can be provoked in osteoporotic subjects as a consequence of reduction of bone layer's density in jaw-bone and negative remodeling.

AB  - Aim of the study was to assess up-to dated approach to magnetic flux and energy product, and application of magnets to osteoporotic jaw-bone repairing process. Material and methods. Data on small bio-magnets and magnet influence to reparation of bone layers in osteoporotic jaw-bone were analyzed. Structural and attractive force of bio-magnets with 2.8 mm radius (mini magnets with radius range of 2.8 to 4.0 mm) and magnets of 5.4 mm radius, if positioned to denturing base, were considered. Magnetism and magnetic energy forces were counted in miliTesla (or Gauss) units, as well as KJ/3 respectively. Structures of magnets were different, and there were NdFeB, PtFe and Sm integrated metal structures. Results. Resistance to corrosion was attributed to PtFe magnets, and capsulated Sm magnets. Available attractive energy of 159 KJ/3 for PtFe magnets and 80 militesla (800 gauss) for samarium magnets were established. Favorable attractive force of magnetic influx was considered to be 10 mm, stimulating osteoblastic activities and positive bone remodeling. Conclusion. PtFe and samarium (ACMA) magnets should be recommended for usage in reparation of osteoporotic jaw-bones.

Magneti na bazi platine i gvožđa PtFe su bili potpuno otporni na koroziju. Najveća ostvarena energija prodora magnetog fluksa u vitalna tkiva je 159 KJ/3 kod magneta od legiranog gvožđa i platine. Gustina magnetnog fluksa do 80 militesla, odnosno 600-800 gausa i dubina prodora do 10 mm, je izuzetno povoljna u smislu delovanja osteoblasta, inicijacije osteoblastne aktivnosti i mogućnosti reparacije sloja osteoporozom oštećenog koštanog tkiva vilice. Bio-magnete na bazi Pt-Fe i magnete sa dodatkom Sm treba koristiti u cilju reparacije koštanih slojeva vilica oštećenih osteoporozom.

AB  - Introduction Osteopenia and osteoporosis reduce the density and mass of jaw bones. Aim The aim of this study was to present the methods of radiographic analysis in patients with osteoporosis prior to restorative treatment. Method 127 panoramic radiographs (Kodak, USA) and 39 retroalveolar radiographs (KD 58-R 30×40 mm, USA) were used for the analysis of density (DT II 05 densitometer, England) and dimensions of jaw bones with respect to segments corresponding to bone layers. Results The results of this study indicated statistically significant differences in bone density (p lt 0.05 and p lt 0.01) in patients with osteopenia. Bone density was significantly reduced (p lt 0.01 and p lt 0.001) in osteoporotic patients, when compared to controls. Significant reductions of edentulous ridges in osteoporotic patients women X=23.05 mm (kV=30.72%) and X=22.85 mm (kV=28.81%), and men X=28.83 (kV=8.55%) as well as X=25.36 (kV=11.43%), were observed. Conclusion Bone density of the upper and lower jaw is reduced in osteoporotic patients. At the very beginning of restorative prosthodontic therapy of osteoporotic patients, retroalveolar radiographs and panoramic radiographs should be obtained. Reference lines should be assigned, contours of the alveolar and edentulous ridges on radiographs should be analyzed and bone density assessed.
