AB  - Introduction/Objective The pain that originates from musculoskeletal structures of the mastication system is one of the symptoms belonging to the category of temporomandibular disorders or temporomandibular dysfunction (TMD). The objective of the research was to evaluate the effect of therapy with stabilizing occlusal splint in the control of painful symptoms of TMD in comparison with the effect of drug therapy. Methods Using standard Research Diagnostic Criteria for Temporomandibular Disorders diagnostic protocol proposed by Dworkin and LeResche, a group of 44 patients with painful TMD was included. The patients were divided into three treatment groups by random selection. The first group was treated with stabilization occlusal splint for a period of one month. In the two control groups, therapy with non-steroidal anti-inflammatory drug ibuprofen (Brufen, Mylan, Canonsburg, PA, USA) or a combination therapy of ibuprofen and diazepam, a medication from the benzodiazepine family (Diazepam, Hemofarm, Vršac, Serbia) was carried out over a period of three weeks. In order to assess the effects of the therapy with stabilizing occlusal splint and the drug therapy, before and after the therapy, pain intensity measurements were performed with visual analogue scale and digital pressure algometer. Results A significant reduction in the intensity of painful symptoms was achieved in all three therapeutic groups. No significant differences in the effectiveness of pain reduction between the proposed therapeutic modalities were noted. Conclusion The obtained results confirm that the therapy with stabilization occlusal splint is a valid procedure in the reduction of pain in patients with TMD.
AB  - Uvod/Cilj Bol porekla mišićno-skeletnih struktura mastikatornog sistema predstavlja jedan od simptoma koji pripadaju kategoriji temporomandibularnih poremećaja ili temporomandibularnih disfunkcija (TMD). Cilj istraživanja je bio da se proceni efekat terapije stabilizacionim okluzalnim splintom u kontroli bolnih simptoma TMD u poređenju sa efektom terapije lekovima. Metode Korišćenjem standardnog dijagnostičkog protokola (RDC/TMD) predloženog od strane Dvorkina i Lerešea, izdvojena je grupa od 44 bolesnika sa bolnim temporomandibularnim disfunkcijama. Bolesnici su podeljeni u tri terapijske grupe slučajnim izborom. Prva grupa je podvrgnuta terapiji stabilizacionim okluzalnim splintom u periodu od mesec dana. U dve kontrolne grupe je sprovedena terapija nesteroidnim antiinflamatornim lekom ibuprofenom (brufen, Mylan) ili kombinacijom ibuprofena i leka iz grupe benzodiazepina - diazepama (diazepam, Hemofarm) u periodu od tri nedelje. U cilju procene efekata terapije stabilizacionim okluzalnim splintom i terapije lekovima, pre i posle sprovedene terapije izvedena su merenja intenziteta bola vizuelnom analognom skalom i digitalnim pritisnim algometrom. Rezultati U sve tri terapijske grupe postignuto je značajno smanjenje intenziteta bolnih simptoma. Nisu zabeležene značajne razlike u uspešnosti smanjenja bola između predloženih terapijskih modaliteta. Zaključak Dobijeni rezultati potvrđuju da je terapija stabilizacionim okluzalnim splintom validna procedura u smanjenju bola kod bolesnika sa TMD.

AB  - Introduction/Objective the objective of this paper is to describe the microstructure and mechanical properties of sintered Co-Cr alloy and to emphasize its advantages and disadvantages with respect to the microstructure and mechanical properties of cast Co-Cr alloy. Methods Base Co-Cr alloy, EOSint M EOS Co-Cr SP2 (EOS GmbH, Munch, Germany), was used for the purpose of this research as the base material for sintering metal structures of metal-ceramic restorations. Metal sintering was conducted by using EOSint M 280 device of German origin in a stream of neutral gas - argon. After that, the alloy was heated over a period of 20 minutes at the temperature of 800°C. The chemical composition of the alloy was determined by energy dispersive spectroscopy. Microstructure of the tested alloy samples was examined under an optical metallographic and scanning electron microscope. Physical and mechanical properties were measured in a universal testing machine. The samples were prepared according to the standard ISO 527-1:1993. Results Chemical composition of the sintered Co-Cr alloy, determined by applying energy dispersive spectroscopy, indicated the same qualitative but different quantitative composition compared to cast Co-Cr alloys. The microstructure of the sintered Co-Cr alloy is lamellar in nature, with two dominant phases: ξ-Co and/or ξ-Cr (fcc - face-centered cubic) and γ-Co (hcp - hexagonal close-packed). Mechanical properties of the Co-Cr alloy obtained by applying selective laser melting technology compared to the cast Co-Cr alloy are superior or approximately the same. Conclusion Selective laser melting of the Co-Cr alloy is a good example of new technologies based on digitization. Together with other digitized procedures, this technology is an introduction to a new era in dentistry popularly called Dentistry 4.0. The advantages of the selective laser melting technology with respect to the conventional technology of casting Co-Cr alloy metal structures are precise metal structure fitting and eco-friendly technology.
AB  - Uvod/Cilj Cilj rada je opisati mikrostrukturu i mehaničke karakteristike sinterovane legure Co-Cr i istaći njene prednosti i mane u odnosu na mikrostrukturu i mehaničke karakteristike livene legure Co-Cr. Metode U istraživanju je korišćena bazna legura Co-Cr, Eosint M EOS Co-Cr SP2 (EOS GmbH, Minhen, Nemačka) za sinterovanje metalnih konstrukcija metalokeramičkih nadoknada. Sinterovanje metala je obavljeno na aparatu EOSint M 280 u struji neutralnog gasa argona. Nakon toga legura je žarena 20 minuta na temperaturi od 800° C. Hemijski sastav legure određivan je energodisperzivnom spektroskopijom. Mikrostruktura ispitivanih uzoraka legure posmatrana je na optičkom metalografskom i elektronskom skenirajućem mikroskopu. Fizičko-mehaničke karakteristike merene su na univerzalnoj kidalici. Uzorci su pripremani prema standardu ISO 527-1:1993. Rezultati Hemijski sastav uzoraka sinterovane legure CoCr pokazao je isti kvalitativan ali različit kvantitativan sastav u odnosu na legure Co-Cr za livenje. Mikrostruktura sinterovane legure Co-Cr je lamelarne prirode, u kojoj dominiraju dve faze: e-Co i/ili e-Cr (fcc - face-centred cubic) i g-Co (hcp - hexagonal close-packed). U poređenju sa livenom legurom Co-Cr, mehaničke karakteristike sinterovane legure Co-Cr su bolje ili približno iste. Zaključak Selektivno lasersko topljenje legure Co-Cr je dobar primer novih tehnologija zasnovanih na digitalizaciji. Zajedno sa drugim digitalizovanim procedurama koje prethode, ova tehnologija je predvorje novoj eri u stomatologiji, popularno nazvanoj Dentistry 4.0. Prednosti tehnologije selektivnog laserskog topljenja u odnosu na tehnologiju konvencionalnog livenja metalnih konstrukcija od legure Co-Cr su preciznost naleganja metalne konstrukcije i čista tehnologija.

AB  - This paper shall discuss the importance of protocol application in modern dentistry. Literature data that include recommendations and consensuses in dental practice point out to their presence in available literature, printed papers, reviewed journals and supplements in the form of expert group conclusions. It should be noted that the protocols most commonly rely on valid postulates of different branches of medicine, supported by specific conditions of the environment in which they are implemented. Additionally, in our settings, applicable dentistry protocols are the result of requirements that institutions and practices should fulfill according to renewable accreditation, as well as following recommendations given in the good clinical practice guidelines with different binding obligations levels. Certain protocols offer therapeutic modalities categorized into classes intended to help users to select appropriate treatments. The second part of this paper shall address one such protocol which classifies partially edentulous patients. The emphasis is on the partial edentulism classification recommended by The American College of Prosthodontists (ACP), which relies on four diagnostic criteria essential for therapeutic decision. Edentulous areas location and extent, abutment teeth health, occlusion model, and residual ridge characteristics represent the parameters which have defined the four classes of partial edentulism of different complexity. In this way, comprehensive approach to the clinical status of the patients has, for the first time been offered to the dental practitioners assuring, among others, higher uniformity of professional attitudes in selection of therapeutic modalities.

AB  - The subject of this study is the quantitative adhesion of a UV-curing composite film based on Bis-GMA (Bisphenol A glycidylmethacrylate) / TEGDMA (triethylene glycol dimethacrylate) as a matrix and particles doped with ferrous oxide on a metal substrate. Two different metal substrates: silver and gold-spattered brass with nickel intermediate coating were used in adhesion evaluating. Adhesion was measured using micro-identation and it was compared with the measured wetting angle of composites to the substrate. It has been shown that the substrates, although with similar mechanical properties that are reflected in very close hardness values, differ by achieved adhesive bonding with the polymer UV-cured polymer film. The addition of ceramic particles in the polymer matrix increased the adhesion of the composite film to both substrates, but the adhesion trend was dependent on the substrate type.

AB  - Biocompatibility of dental materials (DM) can be evaluated by gingival crevicular fluid (GCF) oxidative stress (OS) status. The goal of the study was to ascertain influence of dental caries degree, teeth position, and type and amount of applied DM on GCF OS profile. For this purpose, we tested six DMs that were sealed in one session: amalgam (Amg), composites: Tetric EvoCeram and Beautifil (BF), phosphate cement-zinc phosphate and polycarboxylate cements zinc polycarboxylate cements, and glass ionomer cement (GIC). The study included 88 dental outpatients. Follow-up was scheduled at 7th and 30th day. Oxidative stress parameters (malondialdehyde (MDA) and glutathione (GSH) levels and total superoxide dismutase (tSOD) activity) were measured before (0th day) and after the treatment (7th and 30th day) in GCF. Control teeth were mirror-positioned healthy teeth. The DM accomplished the following effects (listed in descending order): increase of GSH in GCF was realized by ZPoC > BF > GIC > Amg; tSOD activity increase by ZPoC > BF > Amg; and MDA decrease by ZPoC > ZPhC > Amg > TEC. Dental caries provokes insignificant rise of OS in GCF. ZPoC and ZPhC showed the highest antioxidant effect, contrary to GIC. Restorations with antioxidant properties may reduce gum diseases initiated by caries lesion, what is of great clinical relevance in dentistry.

AB  - Contemporary dentistry is, first of all, characterized by diverse accelerated development, owing to improvements of information and other technologies, as well as the development of dental materials (shape-memory biomaterials, nanomaterials, biomaterials for application in tissue engineering, etc.). Expert doctrinaire attitudes move from the direction of operative interventions, whereby disease and acute symptoms are primarily treated, towards the strengthening of oral health by minimally invasive procedures. A particular place in patients’ total rehabilitation belongs to numerous esthetic procedures which, to a large extent, make up a wants-based service, led by the patients’ needs and affinities. This paper deals with differences between cosmetic and esthetic dentistry. The complexity of esthetic dentistry, which favors therapy with the change of function parameters in care for the patient, is emphasized. On the other hand, more attention is paid to the need to know and respect ethical and marketing principles that follow any activity of dentists, starting from the first contact with the patient, the selection of certified materials, to the implementation of the appropriate treatment plan. Well-directed communication and comprehensive awareness of the patient, the use of the visual analog scale, consideration of realistic resources in therapy, and the acceptance of de Bono model of adopted parallel thinking are determinants which help dentists define a problem adequately, find quality solutions, open alternative solutions, and reduce the potential risks in patients’ therapy.
AB  - Današnju stomatologiju karakteriše ubrzani razvoj zahvaljujući unapređenju informacionih i drugih tehnologija, kao i razvoju dentalnih materijala (biomaterijali sa memorisanim oblikom, nanomaterijali, biomaterijali za primenu u tkivnom inženjeringu i dr.). Stručni doktrinarni stavovi kreću se iz pravca operativnih intervencija, kojima se primarno saniraju bolest i akutni simptomi, ka jačanju oralnog zdravlja malo invazivnim postupcima. Posebno mesto u sveukupnoj rehabilitaciji bolesnika pripada brojnim estetskim procedurama, koje u velikoj meri čine praksu vođenu potrebama i afi- nitetima bolesnika. U radu se diskutuje o razlikama u poimanju kozmetske i estetske stomatologije. Naglašena je složenost estetske stomatologije, koja daje prednost terapiji sa promenom funkcijskih parametara u zbrinjavanju bolesnika. S druge strane, akcenat se stavlja na potrebu poznavanja i poštovanja etičkih i marketinških načela koja prate svaku aktivnost lekara, počev od prvog kontakta sa bolesnikom, odabira sertifikovanog materijala do realizacije odgovarajućeg terapijskog plana. Dobro usmerena komunikacija i sveobuhvatna informisanost bolesnika, upotreba VAS skale, kao i sagledavanje realnih resursa u terapiji odrednice su koje pomažu stomatologu da definiše problem na pravi način, iznađe kvalitetna rešenja, otvori alternativne solucije i smanji moguće rizike u terapiji bolesnika.

abstract = "Contemporary dentistry is, first of all, characterized by diverse accelerated development, owing to improvements of information and other technologies, as well as the development of dental materials (shape-memory biomaterials, nanomaterials, biomaterials for application in tissue engineering, etc.). Expert doctrinaire attitudes move from the direction of operative interventions, whereby disease and acute symptoms are primarily treated, towards the strengthening of oral health by minimally invasive procedures. A particular place in patients’ total rehabilitation belongs to numerous esthetic procedures which, to a large extent, make up a wants-based service, led by the patients’ needs and affinities. This paper deals with differences between cosmetic and esthetic dentistry. The complexity of esthetic dentistry, which favors therapy with the change of function parameters in care for the patient, is emphasized. On the other hand, more attention is paid to the need to know and respect ethical and marketing principles that follow any activity of dentists, starting from the first contact with the patient, the selection of certified materials, to the implementation of the appropriate treatment plan. Well-directed communication and comprehensive awareness of the patient, the use of the visual analog scale, consideration of realistic resources in therapy, and the acceptance of de Bono model of adopted parallel thinking are determinants which help dentists define a problem adequately, find quality solutions, open alternative solutions, and reduce the potential risks in patients’ therapy., Današnju stomatologiju karakteriše ubrzani razvoj zahvaljujući unapređenju informacionih i drugih tehnologija, kao i razvoju dentalnih materijala (biomaterijali sa memorisanim oblikom, nanomaterijali, biomaterijali za primenu u tkivnom inženjeringu i dr.). Stručni doktrinarni stavovi kreću se iz pravca operativnih intervencija, kojima se primarno saniraju bolest i akutni simptomi, ka jačanju oralnog zdravlja malo invazivnim postupcima. Posebno mesto u sveukupnoj rehabilitaciji bolesnika pripada brojnim estetskim procedurama, koje u velikoj meri čine praksu vođenu potrebama i afi- nitetima bolesnika. U radu se diskutuje o razlikama u poimanju kozmetske i estetske stomatologije. Naglašena je složenost estetske stomatologije, koja daje prednost terapiji sa promenom funkcijskih parametara u zbrinjavanju bolesnika. S druge strane, akcenat se stavlja na potrebu poznavanja i poštovanja etičkih i marketinških načela koja prate svaku aktivnost lekara, počev od prvog kontakta sa bolesnikom, odabira sertifikovanog materijala do realizacije odgovarajućeg terapijskog plana. Dobro usmerena komunikacija i sveobuhvatna informisanost bolesnika, upotreba VAS skale, kao i sagledavanje realnih resursa u terapiji odrednice su koje pomažu stomatologu da definiše problem na pravi način, iznađe kvalitetna rešenja, otvori alternativne solucije i smanji moguće rizike u terapiji bolesnika.",

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 Good and well balanced diet provided by adequate mastication is part of therapy in patients with type 2 diabetes mellitus (DM). The critical period presents the time immediately after teeth extractions; hence, immediate denture is a rational therapeutical choice for diabetic patients. The presence of immediate denture and its compression might compromise wound healing process, affect chewing ability, food intake and consequently blood glucose level in type 2 DM patients. Objective The objective of this study was to compare socket opening diameters (SOD), chewing ability, changes in blood glucose level and food intake in type 2 DM patients with and without maxillary immediate complete denture (MICD) during a three-week wound healing period. Methods The study comprised 78 type 2 DM partially removable denture wearers (42 candidates for teeth extractions and 36 candidates for teeth extractions and insertion of MICDs). During the three-week period participants were followed for SOD, chewing ability and changes in blood glucose level and food intake. Results Patients with MICD showed significantly lower reduction of SOD (seventh, 14th, 21st day) and higher chewing ability (seventh, 14th, 21st day) in comparison to patients without an MICD. Significantly lower number of patients with an MICD had changes in blood glucose level and food intake. Conclusion Maxillary immediate complete denture presents a good therapeutic choice for type 2 DM patients, as it provides possibility of adequate mastication after teeth extractions and maintenance of nutritional status and blood glucose level.
AB  - Uvod Redovna i balansirana ishrana obezbeđena adekvatnom mastikacijom je značajan deo terapije pacijenata sa dijabetesom melitusom tipa 2 (DM tip 2). Kritičan period za ove bolesnike jeste vreme neposredno nakon ekstrakcije zuba, pa za njih imedijatna proteza predstavlja terapijski izbor. Prisustvo imedijatne proteze i kompresija koju izaziva mogu kompromitovati proces zarastanja, uticati na sposobnost žvakanja, količinu unete hrane, a time i nivo glikemije kod pacijenata obolelih od ovog tipa dijabetesa. Cilj rada Cilj istraživanja je poređenje dijametra ekstrakcionih alveola (DEA), sposobnosti žvakanja, promene količine unete hrane i glikemije kod DM tipa 2 pacijenata sa gornjom totalnom imedijatnom protezom (GTIP) i bez nje. Metode rada Istraživanje je obuhvatilo 78 DM tipa 2 pacijenata, nosilaca parcijalnih pločastih proteza (42 pacijenta indikovana za ekstrakcije zuba i 36 pacijenata indikovanih za ekstrakcije zuba i dobijanje GTIP). Tokom postekstrakcionog perioda od tri nedelje kod pacijenata su praćeni DEA, sposobnost žvakanja, promena količine unete hrane i glikemije. Rezultati Pacijenti sa GTIP pokazali su značajno manju redukciju DEA (7, 14, 21. dana), veću sposobnost žvakanja (7, 14, 21. dana) u odnosu na pacijente bez GTIP. Značajno manji broj pacijenata sa GTIP imao je promene u glikemiji i unošenju hrane u odnosu na grupu bez GTIP. Zaključak Imedijatna proteza predstavlja terapijski izbor kod pacijenata sa DM tipa 2, budući da omogućava dobru mastikaciju nakon ekstrakcija, uz održanje nutricionog statusa i glikemije.

AB  - Background/Aim. Quality of life related to health should be seen as a multidimensional concept that, in addition to the physical symptoms associated with a disease and treatment, should include physical, psychological and social functioning of a person. The primary objective of this study was to use the Serbian preliminary version of the Geriatric Oral Health Assessment Index (GOHAI) questionnaire in order to examine the consistency, reliability and stability, as well as an introduction to the verification tool. Methods. The GOHAI questionnaire with 6-level Likert scale, translated into Serbian, including the relevant oral health characteristics (oral hygiene, required dentures, number of teeth extracted), was filled by five specialists in prosthodontics for 30 randomly selected respondents, before and after the dental prosthetic treatment. Subsequently, in order to measure the reliability of the questionnaire, 27 patients were reinterviewed. Results. The value of Cronbach's Alpha Coefficient (Crα) before the treatment was 0.878, and after the treatment it was 0.788 confirming the internal consistency and stability of the questionnaire. The validity of discriminatory properties of the GOHAI was confirmed by the Spearman's correlation coefficient (r), which was highly significantly associated with oral health characteristics, confirming the high reliability of the measurement. The results of test-retest analysis measured by the individual Pearson's correlation coefficient (r) were in the range of 0.34-0.97, and for the total score r was 0.927, while the Kappa coefficient was 0.63. The correlation analysis of the GOHAI score before the treatment showed that for 10 questions there was a statistically significant correlation of the score with the answers to the questions, and for 6 questions Spearman's r was ≥ 0.7. After the treatment a highly significant correlation of the GOHAI was shown with the answers to 10 questions, while for 5 questions the Spearman's r was > 0.6. The GOHAI average score before the treatment was 19.44 ± 11.12, and after the treatment 2.77 ± 3.83, where the lower value indicates better quality of life. Conclusion. The results of this pilot study confirm internal consistency and stability of the Serbian preliminary version of the GOHAI questionnaire and the causal relation between the quality of life and the characteristics of oral health of the patients with dentures. Accordingly, instrument verification is recommended.

AB  - Bacground/Aim. The radiopacity of an endodontic material can considerably vary as measured on film and a digital sensor. Digital radiography offers numerous advantages over convential film-based radiography in dental clinical practice regarding both diagnostic capabilities and postintervention procedures. The aim of this study was to investigate the capacity of conventional and charge-conpled device (CCD) based digital radiography to detect material on radiograph depending on the radio-pacifying agent present in the material. Methods. Experimental cements were formulated by mixing Portland cement with the following radiopacifying agents: zinc oxide (ZnO), zirconium oxide (ZrO2), titanium dioxide (TiO2), barium sulphate (BaSO4), iodoform (CHI3), bismuth oxide (Bi2O3) and ytterbium trifluoride (YbF3). In addition, 5 endodontic materials comprising Endomethasone®, Diaket®, N2®, Roth 801® and Acroseal® were investigated to serve as control. Per three specimens of each material were radiographed alongside an aluminum step wedge on film (Eastman Kodak Company®, Rochester, NY) and a CCD-based digital sensor (Trophy Radiologie®, Cedex, France). Radiopacity values were calculated by converting the radiographic densities of the specimens expressed as a mean optical densities or mean grey scale values into equivalent thickness of aluminum. Results. Twoway ANOVA detected no significant differences with respect to the imaging system (p > 0.05), but the differences were significant with respect to radiopacifier (p  lt  0.001) and the interaction of the two factors (p  lt  0.05). Paired ttest revealed significant differences between the methods used for pure Portland cement, all concentrations of BaSO4 and CHI3, 10% and 20% additions of ZrO2 and Bi2O3 and 10% and 30% addition of YbF3 (p  lt  0.05). Conclusion. The materials which incorporate CHI3 or BaSO4 as radiopacifying agents are expected to be significantly more radiopaque on a digital sensor than on film. During clinical practice one should concern to the quality of contrast assessement obtained by digital according to conventional radiography.

AB  - Introduction Antioxidants protect against reactive oxygen species and expose beneficial anti-inflammatory activity when in contact with biological tissues. Dental materials that are used as temporary luting on fixed dental restorations are often in contact with injured gingival tissue, hence they should contain anti-inflammatory characteristics that are essential after prosthetic procedures preceding cementation of final restauration. Objective The aim of this study was to investigate the antioxidant effect through the oxidation inhibition (OI) of mixed dental cement for temporary luting or their liquid component. Methods Eight study groups were prepared each by ten samples: 1) ex tempore preparation of zinc-oxide eugenol paste (Kariofil Z Galenika, Serbia), 2) Viko Temp paste (Galenika, Serbia), 3) Temp Bond NE paste (Kerr, Germany), 4) ScutaBond (ESPE, Germany), 5) Cp-CAP paste (Germany, Lege Artis) and oil component of 6) Kariofil Z, 7) Viko Temp and 8) Cp-CAP. The samples were subjected to spectrophotometer to measure OI 2,2'-azino-di-(3-ethyl-benzthiazoline-6-sulphonic acid) (ABTS) using Randox kit, United Kingdom. The control samples were pure ascorbic acid (1% w/v). Results High values of OI exposed materials (groups 1, 5, 6, 7, 8) with content of eugenol (or its derivates) in the range of 100-88.8% were statistically more significant than the values of non-eugenol substances (groups 2, 3, 4) with the range of 8.2-43.5%. Conclusion Eugenol containing temporary fixation materials show significant antioxidative properties and therefore they may be used in those clinical situations where surrounding gingival tissue is injured during restorative procedure.

Cilj rada Cilj ispitivanja je bio da se pomoću zabeleženih vrednosti inhibicije oksidacije (IO) utvrdi antioksidativni efekat nekoliko pripremljenih preparata za privremeno cementiranje i njihovih tečnih komponenata.

Uzorci su podvrgnuti spektrofotometru radi merenja vrednosti IO na ABTS primenom seta reagensa (Randox kit, Velika Britanija). Kontrolnu grupu su činili uzorci čiste askorbinske kiseline (1% w/v). Rezultati Visoke vrednosti IO ispoljili su uzorci u grupama eugenolnih materijala 1, 5, 6, 7 i 8 u rasponu od 88,8% do 100%, što je bilo statistički značajno u odnosu na niže vrednosti kod neeugenolnih materijala (raspon 8,2-43,5%) u grupama 2, 3 i 4. Zaključak Nije zabeležena statistička značajna razlika u vrednostima IO međusobnim poređenjem eugenolnih grupa (p>0,05). Poređenjem vrednosti IO između neeugenolnih grupa, samo je kod grupe 4 utvrđena statistički značajna razlika prema grupama 2 i 3 (p lt 0,01). Poređenjem uzoraka 2 i 3 zabeležena je statistički beznačajna razlika za vrednosti IO (p>0,05).

AB  - This paper discusses the preparation of tooth design for porcelain veneers. It follows the literature more than three past decades. From the very beginning, the porcelain veneers were placed to no/minimally prepared tooth substance, showing different problems in clinical use. Later, the technique of etching the porcelain and controlling the reduction of tooth structure presented the great steps forward in porcelain veneers accepting. The special accent concerning the preparative design was placed on variations of incisal edge preparation - the problem, which is still present in current practice. Additionally, the paper emphasizes the extremely demanding protocols in making the porcelain veneers, as well as their expanded clinical indications.
AB  - Rad diskutuje preparativni dizajn zuba u izradi porcelanskih faseta kroz literaturni revijalni osvrt duži od tri decenije. Upoznajući se sa porcelanskim fasetama, dentalna profesija nije prepoznavala na pravi način značaj preparacije zuba koji će nositi fasete, pa su fasete aplikovane na nepreparine površine zuba. Veliki korak napred u kliničkoj prihvatljivosti porcelanskih faseta donela je tehnika nagrizanja površine gleđi i kontrolisana redukcija ovog tkiva. Poseban akcenat u uspešnoj ekspolataciji faseta predstavlja iznalaženje odgovarajućeg dizajna incizalne ivice, kao i rešavanje problema fraktura tankih porcelanskih faseta. U vezi sa tim, rad diskutuje jedan od modaliteta u preparaciji incizalne ivice koji uključuje samo njeno skraćivanje do 2mm, but joint dizajn. Istraživanja pokazuju niz prednosti ovog dizajna u odnosu na palatinalni žleb: optimalan odnos keramike i cementa na palatinalnoj strani, smanjen rizik od postcemetirajućeg loma nastalog polimerizacionom kontrakcijom i prirodnim temperaturnim varijacijama u ustima i dr. Uz to, ovaj dizajn omogućava prezervaciju perifernog sloja gleđi, koji je kritičan u eliminaciji mikropukotine na palatinalnom spoju fasete i zuba, jasno se suprostavljajući silama smicanja. Skraćivanje incizalne ivice je jednostavnije, brže, a laboratorijski model je jasniji. Ravna površina ostavlja bolji oslonac keramičkoj faseti, pa su i rizici loma tankih palatinalnih ivica keramike kontrolisani ovim dizajnom. U novije vreme, prošireno indikativno polje u izradi faseta, koje je donelo brojne specifičnosti u preparativnoj tehnici i dizajnu zuba, biva kritikovano od 'back to future' promotera u struci, koji se zalažu za upotrebu tankih non-prep porcelanskih faseta. Uz to, revijalni pregled apostrofira značaj poštovanja veoma zahtevnih, različitih kliničkih faza u preparaciji zuba za prihvatanje soficticiranog konzervativnog modaliteta u struci, kakve su porcelanske fasete.

abstract = "This paper discusses the preparation of tooth design for porcelain veneers. It follows the literature more than three past decades. From the very beginning, the porcelain veneers were placed to no/minimally prepared tooth substance, showing different problems in clinical use. Later, the technique of etching the porcelain and controlling the reduction of tooth structure presented the great steps forward in porcelain veneers accepting. The special accent concerning the preparative design was placed on variations of incisal edge preparation - the problem, which is still present in current practice. Additionally, the paper emphasizes the extremely demanding protocols in making the porcelain veneers, as well as their expanded clinical indications., Rad diskutuje preparativni dizajn zuba u izradi porcelanskih faseta kroz literaturni revijalni osvrt duži od tri decenije. Upoznajući se sa porcelanskim fasetama, dentalna profesija nije prepoznavala na pravi način značaj preparacije zuba koji će nositi fasete, pa su fasete aplikovane na nepreparine površine zuba. Veliki korak napred u kliničkoj prihvatljivosti porcelanskih faseta donela je tehnika nagrizanja površine gleđi i kontrolisana redukcija ovog tkiva. Poseban akcenat u uspešnoj ekspolataciji faseta predstavlja iznalaženje odgovarajućeg dizajna incizalne ivice, kao i rešavanje problema fraktura tankih porcelanskih faseta. U vezi sa tim, rad diskutuje jedan od modaliteta u preparaciji incizalne ivice koji uključuje samo njeno skraćivanje do 2mm, but joint dizajn. Istraživanja pokazuju niz prednosti ovog dizajna u odnosu na palatinalni žleb: optimalan odnos keramike i cementa na palatinalnoj strani, smanjen rizik od postcemetirajućeg loma nastalog polimerizacionom kontrakcijom i prirodnim temperaturnim varijacijama u ustima i dr. Uz to, ovaj dizajn omogućava prezervaciju perifernog sloja gleđi, koji je kritičan u eliminaciji mikropukotine na palatinalnom spoju fasete i zuba, jasno se suprostavljajući silama smicanja. Skraćivanje incizalne ivice je jednostavnije, brže, a laboratorijski model je jasniji. Ravna površina ostavlja bolji oslonac keramičkoj faseti, pa su i rizici loma tankih palatinalnih ivica keramike kontrolisani ovim dizajnom. U novije vreme, prošireno indikativno polje u izradi faseta, koje je donelo brojne specifičnosti u preparativnoj tehnici i dizajnu zuba, biva kritikovano od 'back to future' promotera u struci, koji se zalažu za upotrebu tankih non-prep porcelanskih faseta. Uz to, revijalni pregled apostrofira značaj poštovanja veoma zahtevnih, različitih kliničkih faza u preparaciji zuba za prihvatanje soficticiranog konzervativnog modaliteta u struci, kakve su porcelanske fasete.",

AB  - Composites with the addition of alumina nanofillers show improvement in mechanical properties.Poly(methyl methacrylate), PMMA, was used as a matrix and two different types of nanofillers having extremely different shapes were added into the matrix to form the composites. The reinforcements were based on alumina nanoparticles having either a spherical shape or whiskers with a length to diameter ratio of 100. The influence of the size and shape of the alumina fillers and the loading on the mechanical properties of the prepared composite were studied using nanoindentation measurements and dynamic mechanical analysis. It was observed that both alumina whiskers and spherical alumina nanoparticles added in the PMMA matrix improved the mechanical properties of the composites, but the improvement was significantly higher with reinforcement by alumina whiskers. The concentration of the reinforcing spherical alumina nanoparticles and alumina whiskers in the PMMA matrix varied up to 5 wt. %. The best performance was obtained by the addition of 3 wt. % of alumina whiskers in the PMMA matrix in terms of the mechanical properties of the obtained composite.

AB  - Background/Aim. Dimensional stability and accuracy of an impression after chemical disinfection by immersion in disinfectants are crucial for the accuracy of final prosthetic restorations. The aim of this study was to assess the deformation of addition and condensation silicone impressions after disinfection in antimicrobial solutions. Methods. A total of 120 impressions were made on the model of the upper arch representing three full metal-ceramic crown preparations. Four impression materials were used: two condensation silicones (Oranwash L - Zhermack and Xantopren L Blue - Heraeus Kulzer) and two addition silicones (Elite H-D + regular body - Zhermack and Flexitime correct flow - Heraeus Kulzer). After removal from the model the impressions were immediately immersed in appropriate disinfectant (glutaraldehyde, benzalkonium chloride - Sterigum and 5.25% NaOCl) for a period of 10 min. The control group consisted of samples that were not treated with disinfectant solution. Consecutive measurements of identical impressions were realized with a Canon G9 (12 megapixels, 2 fps, 6x/24x), and automated with a computer Asus Lamborghini VX-2R Intel C2D 2.4 GHz, by using Remote Capture software package, so that time-depending series of images of the same impression were obtained. Results. The dimensional changes of all the samples were significant both as a function of time and the applied disinfectant. The results show significant differences of the obtained dimensional changes between the group of condensation silicones and the group of addition silicones for the same time, and the same applied disinfectant (p = 0.026, F = 3.95). Conclusion. The greatest dimensional changes of addition and condensation silicone impressions appear in the first hour after their separation from the model.

AB  - Purpose: The aim of this in vitro study was to investigate the potential of digital and conventional radiography to detect small amounts of residual dental luting cements around implant abutments. Materials and Methods: Artificial cement and aluminum overhangs in varying thicknesses, heights, and depths were radiographed adjacent to implant restorations with a radiovisiography sensor. Five trained evaluators were asked to identify the smallest depth of overhang that could be detected on radiographs. Results: For detection of cement overhangs adjacent to implant abutments, a luting agent must have greater radiopacity than what is recommended by relevant International Organization for Standardization directives. To detect a 0.1-mm-thick portion of excess cement adjacent to an implant abutment, the cement should have a radiopacity of at least 1.7 mm of aluminum for high-resolution digital radiographs and 2.2 mm of aluminum for film-based radiographs. Two-way analysis of variance revealed that the thickness of the specimens, type of imaging detector, and type of cement all affected the radiopacity threshold for artificial cement excess (P  lt  .05). The height of the specimens and the surrounding structures were not statistically significant factors in cement detection. Conclusions: Digital radiography offers better possibilities for visualization of cement excess than conventional radiography.

AB  - This article presents a literature review on the resin bond to zirconia ceramic. Modern esthetic dentistry has highly recognized zirconia, among other ceramic materials. Biocompatibility of zirconia, chemical and dimensional stability, excellent mechanical properties, all together could guarantee optimal therapeutical results in complex prosthodontic reconstruction. On the other hand, low thermal degradation, aging of zirconia as well as problematic bonding of zirconia framework to dental luting cements and tooth structures, opened the room for discussion concerning their clinical durability. The well known methods of mechanical and chemical bonding used on glass-ceramics are not applicable for use with zirconia. Therefore, under critical clinical situations, selection of the bonding mechanism should be focused on two important points: high initial bond strength value and long term bond strength between zirconia-resin interface. Also, this paper emphases the use of phosphate monomer luting cements on freshly air-abraded zirconia as the simplest and most effective way for zirconia cementation procedure today.

AB  - Objective: According to the ISO, the radiopacity of luting cements should be equal to or greater than that of aluminum. The aim of this in vitro study was to determine the radiopacity of 13 commercially available dental luting cements and compare them with human enamel and dentin. Method and Materials: Five classes of luting cements were evaluated: zine phosphate (Cegal N and Harvard Zine Phosphate), zine polycarboxylate (Harvard Polycarboxylate and Hoffmann's Carboxylate), glass ionomers (Ketac Cem Fasymix, Ketac Cem Radiopaque, and Fuji I), resin-modified glass ionomer (Rely X Luting), and resin cements (Multilink Automix, Variolink II, Speed CEM, Rely X Unicem Automix, and three shades of Variolink Veneer). Tooth slices served as controls. Five specimens of each material measuring 8 mm in diameter and 1 mm thick were prepared and radiographed alongside tooth slices and an aluminum stepwedge using a Trophy RVG sensor. The radiopacity values were expressed in mm Al and analyzd by the ANOVA and Tukey tests (P  lt  .05). Results: All the cements examined except Variolink Veneer had significantly higher radiopacities than that of dentin. Rely X Unicem Automix, glass ionomer, and resin-modified glass-ionomer cements demonstrated radiopacities that were not significantly different with respect to enamel. Zinc phosphate, zinc polycarboxylate, and three of the resin cements presented radiopacity values that were significantly greater than that of enamel. Conclusion: Almost all the investigated materials presented an acceptable radiopacity. Radiopacity of dental cements seems to depend more on the presence of elements with high atomic numbers than on the type of the material. (Quintessence Int 2012; 43: 421-428)

AB  - In this study, spherical particles of hydroxyapatite (HA) and alpha-tricalcium phosphate (alpha-Ca-3(PO4)(2): alpha-TCP) doped with different amounts of silicon were used for the preparation of scaffolds. The scaffolds were obtained by a replica foam method using particles of narrow size distribution pre-annealed at 1150 degrees C with different alpha-TCP and HA contents in order to investigate the effect of composition on their morphological and mechanical properties. Morphology, size, and distribution of the particles were characterized using scanning electron microscopy and particle size analyzer. The obtained alpha-TCP-HA scaffolds had compressive strengths up to 5.7 MPa with a uniform and interconnected porous structure. X-ray diffraction analysis used to determine the crystal structure of the scaffolds confirmed that the alpha-TCP-HA content could be controlled by the amount of silicon ions.

AB  - Introduction. Microleakage is defined as the clinically undetectable seepage of oral fluids containing bacteria and debris between cement layer and tooth restoration. Objective. This in vitro study investigated the effect of different dental cements (zinc-phosphate, polycarboxylate, glass-ionomer and resin cement) on microleakage in different ceramic crown systems (metal ceramic crown, metal ceramic crown with a porcelain margin, Empress 2 and In Ceram all-ceramic crowns) fixed on extracted human teeth. Methods. One hundred and sixty intact human premolars were randomized to four groups of forty teeth each, according to the different ceramic crown systems. They were prepared in a standardized manner for metal-ceramic and all-ceramic crowns. Crowns were made following a standard laboratory technique, and each group of crowns were divided into four groups according to the different cement agents and cemented on their respective abutments. The specimens were subjected to thermocycling, placed in methylene blue solutions, embedded in resin blocks and vertically cut in the bucco-oral and meso-distal direction. The microleakage in the area of tooth-cement interface was defined as linear penetration of methylene blue and was determined with a microscope to assign microleakage scores using a five-point scale. Results. A significant association was found between a cement type and degree of microleakage (p=0.001). No statistically significant differences were found among the different ceramic crown systems luted with the same dental cement. The smallest degree of microleakage was observed in specimens luted with resin cement (X=1.73), followed by glass-ionomer cement (X=2.45) and polycarboxylate cement (X=3.20). The greatest degree of microleakage was detected in the crowns fixed with zincphosphate cement (X=3.33). Conclusion. The investigated dental cements revealed different sealing abilities. The use of resin cement resulted in the percentage of 0 microleakage scores. Due to this feature, the resin cement is to be recommended in everyday clinical practice.
AB  - Uvod. Mikropropustljivost je klinički neuočljivo prodiranje tečnosti, bakterija, molekula i jona između cementnog sloja i dentina ili cementnog sloja i nadoknade. Ovaj problem je od velikog praktičnog značaja za trajnost fiksnih nadoknada. Cilj rada. Cilj ovog istraživanja in vitro bio je da se ispita uticaj različitih dentalnih cementa (cink-fosfatni, polikarboksilatni, glasjonomer i kompozitni cement) na mikropropustljivost krunica izrađenih od različitih materijala (metalokeramičke, metalokeramičke s rubom u keramici i keramičke krunice Empress2 i In Ceram Alumina), cementiranih na eksperimentalnim modelima ekstrahovanih zuba. Metode rada. Korišćeno je 160 ekstrahovanih intaktnih premolara koji su prema vrsti krunice svrstani u četiri grupe sa po 40 uzoraka u svakoj. Zubi su uobičajenim postupkom pripremljeni za prihvatanje metalokeramičkih i keramičkih krunica. Odgovarajućim laboratorijskim postupkom izrađene su krunice. Unutar svake grupe izvršena je dodatna podela uzoraka na četiri podgrupe od po 10 eksperimentalnih parova, u zavisnosti od tipa cementa kojim je krunica cementirana. Cementirani parovi su podvrgnuti termocikliranju, potopljeni u rastvor metilen-plavog, postavljeni u blokove epoksi smole, a zatim sečeni paralelno s aksijalnom osom zuba u meziodistalnom i bukooralnom pravcu. Mikropropustljivost je definisana kao dubina linearnog prodora boje duž spoja dentina i cementa, procenjena je primenom mikroskopa i iskazana skalom sa gradacijom u prodoru boje od 0 do 5 bodova. Rezultati. Analizom dobijenih rezultata uočena je statistički značajna povezanost između vrste cementa i stepena mikropropustljivosti (p=0,001). Analizom dubine prodora boje između različitih krunica cementiranih istom vrstom cementa nije uočena statistički značajna razlika. Statistički značajno najmanje vrednosti mikropropustljivosti zabeležene su kod kompozitnog cementa (srednja vrednost bodova 1,73), nešto veće vrednosti pokazao je glasjonomer (srednja vrednost bodova 2,45) i polikarboksilatni cement (srednja vrednost bodova 3,20). Najveći stepen mikropropustljivosti uočen je kod krunica cementiranih cink-fosfatnim cementom (srednja vrednost bodova 3,33). Zaključak. Ispitivani dentalni cementi imaju različitu sposobnost rubnog zatvaranja. Najmanja mikropropustljivost, iskazana sa 0 bodova, zabeležena je kod kompozitnog cementa, zbog čega se on preporučuje za primenu u svakodnevnoj kliničkoj praksi.

This in vitro study investigated the effect of different dental cements (zinc-phosphate, polycarboxylate, glass-ionomer and resin cement) on microleakage in different ceramic crown systems (metal ceramic crown, metal ceramic crown with a porcelain margin, Empress 2 and In Ceram all-ceramic crowns) fixed on extracted human teeth. Methods. One hundred and sixty intact human premolars were randomized to four groups of forty teeth each, according to the different ceramic crown systems. They were prepared in a standardized manner for metal-ceramic and all-ceramic crowns. Crowns were made following a standard laboratory technique, and each group of crowns were divided into four groups according to the different cement agents and cemented on their respective abutments. The specimens were subjected to thermocycling, placed in methylene blue solutions, embedded in resin blocks and vertically cut in the bucco-oral and meso-distal direction. The microleakage in the area of tooth-cement interface was defined as linear penetration of methylene blue and was determined with a microscope to assign microleakage scores using a five-point scale. Results. A significant association was found between a cement type and degree of microleakage (p=0.001). No statistically significant differences were found among the different ceramic crown systems luted with the same dental cement. The smallest degree of microleakage was observed in specimens luted with resin cement (X=1.73), followed by glass-ionomer cement (X=2.45) and polycarboxylate cement (X=3.20). The greatest degree of microleakage was detected in the crowns fixed with zincphosphate cement (X=3.33). Conclusion. The investigated dental cements revealed different sealing abilities. The use of resin cement resulted in the percentage of 0 microleakage scores. Due to this feature, the resin cement is to be recommended in everyday clinical practice., Uvod. Mikropropustljivost je klinički neuočljivo prodiranje tečnosti, bakterija, molekula i jona između cementnog sloja i dentina ili cementnog sloja i nadoknade. Ovaj problem je od velikog praktičnog značaja za trajnost fiksnih nadoknada. Cilj rada. Cilj ovog istraživanja in vitro bio je da se ispita uticaj različitih dentalnih cementa (cink-fosfatni, polikarboksilatni, glasjonomer i kompozitni cement) na mikropropustljivost krunica izrađenih od različitih materijala (metalokeramičke, metalokeramičke s rubom u keramici i keramičke krunice Empress2 i In Ceram Alumina), cementiranih na eksperimentalnim modelima ekstrahovanih zuba. Metode rada. Korišćeno je 160 ekstrahovanih intaktnih premolara koji su prema vrsti krunice svrstani u četiri grupe sa po 40 uzoraka u svakoj. Zubi su uobičajenim postupkom pripremljeni za prihvatanje metalokeramičkih i keramičkih krunica. Odgovarajućim laboratorijskim postupkom izrađene su krunice. Unutar svake grupe izvršena je dodatna podela uzoraka na četiri podgrupe od po 10 eksperimentalnih parova, u zavisnosti od tipa cementa kojim je krunica cementirana. Cementirani parovi su podvrgnuti termocikliranju, potopljeni u rastvor metilen-plavog, postavljeni u blokove epoksi smole, a zatim sečeni paralelno s aksijalnom osom zuba u meziodistalnom i bukooralnom pravcu. Mikropropustljivost je definisana kao dubina linearnog prodora boje duž spoja dentina i cementa, procenjena je primenom mikroskopa i iskazana skalom sa gradacijom u prodoru boje od 0 do 5 bodova. Rezultati. Analizom dobijenih rezultata uočena je statistički značajna povezanost između vrste cementa i stepena mikropropustljivosti (p=0,001). Analizom dubine prodora boje između različitih krunica cementiranih istom vrstom cementa nije uočena statistički značajna razlika. Statistički značajno najmanje vrednosti mikropropustljivosti zabeležene su kod kompozitnog cementa (srednja vrednost bodova 1,73), nešto veće vrednosti pokazao je glasjonomer (srednja vrednost bodova 2,45) i polikarboksilatni cement (srednja vrednost bodova 3,20). Najveći stepen mikropropustljivosti uočen je kod krunica cementiranih cink-fosfatnim cementom (srednja vrednost bodova 3,33). Zaključak. Ispitivani dentalni cementi imaju različitu sposobnost rubnog zatvaranja. Najmanja mikropropustljivost, iskazana sa 0 bodova, zabeležena je kod kompozitnog cementa, zbog čega se on preporučuje za primenu u svakodnevnoj kliničkoj praksi.",

AB  - Introduction. The influence of occlusal condition at the onset of temporomandibular disorders (TMD) has been strongly debated for many years and still is the source of controversy. Up to the eighties in the last century, the occlusal factors such as the presence of uncured malocclusions, discrepancies between intercuspal position and retruded contact position greater than two millimeters, retrusive and nonworking side interferences and loss of posterior teeth were considered to be the primary causes of TMD. Objective. The aim of this study was to estimate the role of occlusal factor in the etiology of craniomandibular dysfunction and therapeutic effects of irreversible occlusal therapy (occlusal equilibration) in patients with TMD. Methods. In the investigation we studied a group of 200 men and women. The average age of the selected patients was between18 and 25 years. The purpose of TMD signs and symptoms was confirmed in every patient using a special functional analysis and evaluating the craniomandibular index (CMI) according to Fricton and Schiffman. The value of craniomandibular index was determined in the group of 15 patients with signs and symptoms of temporomandibular dysfunction. In the study groups occlusal equilibration (selective grinding) was performed according to Okeson using the central position of the mandible as the referent position in the occlusal therapy. The value of CMI was determined before and 30 days after occlusal equilibration. Results. The results of this study confirmed the significant reduction in the signs and symptoms of TMD after occlusal equilibration. The statistical elaboration of the differences between the values of CMI I (before treatment) and CMI II (30 days after treatment) revealed highly significant differences. The CMI I values in the group ranged between 0.076 and 0.346 with the mean value of 0.188±0.082.The values of CMI II ranged between 0.038 and 0.19 with the mean value of 0.038±0.053. Conclusion. The study conformed the validity of irreversible occlusal therapy (selective grinding) in patients with TMD.

Cilj rada. Cilj rada je bio da se utvrdi uloga okluzivnih faktora u razvoju TMD i oceni uspeh primene ireverzibilne okluzivne terapije (selektivno brušenje) kod osoba sa TMD. Metode rada. U svrhu istraživanja pregledano je 200 osoba oba pola uzrasta 18-25 godina. Znaci i simptomi TMD su vrednovani na osnovu posebne funkcionalne analize i izraženi kraniomandibularnim indeksom (CMI) po Friktonu (Fricton) i Šifmanu (Schiffman). Na osnovu ovoga indeksa formirana je studijska grupa koju je činilo 15 ispitanika sa znacima i simptomima TMD. Kod njih je urađeno selektivno uklanjanje okluzivnih smetnji brušenjem prema metodi Oksona (Okeson) korišćenjem centralnog položaja kao referentnog položaja tokom okluzivne terapije.

AB  - INTRODUCTION Crown displacement often occurs because the features of tooth preparations do not counteract the forces directed against restorations. OBJECTIVE The purpose of this study was to evaluate the effect of preparation designs on retention and resistance of fixed restorations. METHOD The study was performed on 64 differently sized stainless steel dies. Also, caps which were used for evaluated retention were made of stainless steel for each die. After cementing the caps on experimental dies, measuring of necessary tensile forces to separate cemented caps from dies was done. Caps, which were made of a silver-palladium alloy with a slope of 60° to the longitudinal axis formed on the occlusal surface, were used for evaluating resistance. A sudden drop in load pressure recorded by the test machine indicated failure for that cap. RESULTS A significant difference was found between the tensile force required to remove the caps from the dies with different length (p lt 0.05) and different taper (p lt 0.01). The greatest retentive strengths (2579.2 N and 2989.8 N) were noticed in experimental dies with the greatest length and smallest taper. No statistically significant (p>0.05) differences were found between tensile loads for caps cemented on dies with different diameter. Although there was an apparent slight increase in resistance values for caps on dies with smaller tapers, the increase in resistance for those preparation designs was not statistically significant. There was a significant difference among the resistance values for caps on dies with different length (p lt 0.01) and diameter (p lt 0.05). CONCLUSION In the light of the results obtained, it could be reasonably concluded that retention and resistance of the restoration is in inverse proportion to convergence angle of the prepared teeth. But, at a constant convergence angle, retention and resistance increase with rising length and diameter.

Najveće vrednosti sila retencije zabeležene su kod eksperimentalnih patrljaka najveće dužine i najmanjeg nagiba aksijalnih površina. Statistički značajna razlika između vrednosti sila zatezanja potrebnih za razdvajanje kapica cementiranih na eksperimentalnim patrljcima različitog prečnika nije uočena (p>0,05). Iako smanjenjem nagiba aksijalnih površina eksperimentalnih patrljaka dolazi do povećanja vrednosti sila pritiska, uočena razlika nije statistički značajna.
