AB  - Dysbiosis of the microbiome on the airway mucosa leads to the development of chronic inflammatory and allergic disorders. The aim of this study was to consider the potential diagnostic criteria for allergic fungal rhinosinusitis (AFRS) and nonallergic fungal rhinosinusitis (FRS), and the role of fungal presence in an environment for the development of AFRS. In this study, 136 patients were divided into two groups: patients with positive specific immunoglobulin E (sIgE) and fungal finding (AFRS group), and patients with negative sIgE and positive fungal finding (FRS group). The study design included: anamnesis data, sIgE, eosinophil count and skin-prick test, rhinology and computerized tomography (CT) observation and mycological finding. Our results showed: (i) the prevalence in Serbia is: AFRS 1.3%, FRS 2.8%; (ii) 30.4% patients with sIgE+ had more often severe and recurrent chronic rhinosinusitis (CRS) (P = .005) and the presence of polyps (P = .025); (iii) 46.4% patients with sIgE+ had positive fungi on the sinonasal mucosa and were considered as AFRS; (iv) patients with AFRS had more frequent asthma (P = .024) and chronicity of CRS > 10 years (P = .000). The persistent fungal presence and prolonged duration of CRS could be a silent threat for the progression of inflammation and development of FRS. Lavage with hypertonic-NaCl should be included in the everyday hygiene routine in an effort to decrease fungal load and antigenic exposure. The presence of allergological parameters and better response to corticosteroid therapy in AFRS patients should be considered as crucial diagnostic criteria for AFRS.

AB  - The salivary glands and pancreas have comparable anatomic and antigenic properties and can share common pathogenetic mechanisms involving toxic or autoimmune processes. The aim of this study is to assess the correlation in size between the normal submandibular glands and the pancreas. The study was based on human autopsy specimens of the pancreas, neck and oral base from 22 adults, both sexes (mean age, 57.9 years). The pancreatic and submandibular ducts were injected with a contrast medium, and the area of the salivary and pancreatic glandular ductograms was measured with the aid of software for quantification of visual information. Samples of tissue from the salivary glands and the pancreas were studied by means of light microscopy. A high correlation was found between the planimetric size of the pancreas and the submandibular glands (correlation coefficient 0.497 and 0.699 for the right and the left gland, respectively). This ratio was close to 5:1. There were no significant differences in size for the left vs. right submandibular gland (p = 0.39). The ductograms were significantly larger in size in males than in females (p  lt  0.001). This study has proven a positive correlation in planimetric size between the normal submandibular glands and pancreas, a result that is expected to have possible clinical implications in the long-term follow-up of patients with chronic pancreatitis.

AB  - Background: Secondary tumours of the hyoid bone and thyroid cartilage are extremely rare. In this paper, we present a case of the hyoid bone and thyroid cartilage metastases in a patient treated for sigmoid colon adenocarcinoma. Case Report: Four years after sigmoid colon adenocarcinoma was diagnosed and treated with surgery and chemotherapy, the patient developed bone metastases in the left sacroiliac joint and right proximal humerus. Although the patient did not complain of any related symptoms, in a bone scintigraphy the accumulation of Technetium-99m was incidentally detected in the two sites of the anterior neck. On ultrasound examination there were two hyperechoic and heterogeneous masses with calcifications placed in front of the hyoid bone and thyroid cartilage. Computerized tomography demonstrated massive hyoid bone and thyroid cartilage destruction. Conclusion: In patients with progressive sigmoid colon adenocarcinoma, destruction of the hyoid bone and thyroid cartilage could be suspected for metastases.

AB  - Background/AimLe Fort lines have traditionally been considered as zones of weakness in the mid-facial skeleton although the structural basis of increased bone fragility at these sites has not yet been investigated. Considering recent findings of occlusal loading-related regional heterogeneity in the mid-facial bone micro-architecture, the aim of this study was to explore whether such heterogeneity in cortical and cancellous bone micro-architecture may contribute to increased fragility at Le Fort fracture sites. Materials and MethodsTwenty-five cortical and thirteen cancellous bone specimens were harvested from a dry skull and analyzed by micro-CT. Specimens were classified into Le Fort or Non-Le Fort groups based on their location in the mid-facial skeleton. ResultsCortical bone along Le Fort lines showed tendencies toward lower thickness (1.50.63 vs 1.75 +/- 0.79; P=.39) and greater porosity (11.48 +/- 5.67 vs 10.28 +/- 5.28; P=.59). A significant difference was detected in the trabecular degree of anisotropy which was higher in cancellous bone from Le Fort fracture sites (2.14 +/- 0.69 vs 1.58 +/- 0.34; P=.02). ConclusionsRegional heterogeneity in cortical bone micro-architecture could not fully explain increased fragility of the mid-facial skeleton at the Le Fort lines. However, regional differences in trabecular bone anisotropy may contribute to increased bone fragility.

AB  - To improve our understanding of hyperostosis frontalis interna (HFI), we investigated whether HFI was accompanied by changes in the postcranial skeleton. Based on head CT scan analyses, 103 postmenopausal women were divided into controls without HFI and those with HFI, in whom we measured the thickness of frontal, occipital, and parietal bones. Women in the study underwent dual energy x-ray absorptiometry to analyze the bone density of the hip and vertebral region and external geometry of the proximal femora. Additionally, all of the women completed a questionnaire about symptoms and conditions that could be related to HFI. Women with HFI had a significantly higher prevalence of headaches, neurological and psychiatric disorders, and a significantly lower prevalence of having given birth. Increased bone thickness and altered bone structure in women with HFI was localized only on the skull, particularly on the frontal bone, probably due to specific properties of its underlying dura. Bone loss in the postcranial skeleton showed the same pattern in postmenopausal women with HFI as in those without HFI. Recording of HFI in medical records can be helpful in distinguishing whether reported disorders occur as a consequence of HFI or are related to other diseases, but does not appear helpful in identifying women at risk of bone loss.

AB  - Although seen frequently during dissections and autopsies, Hyperostosis frontalis interna (HFI) - a morphological pattern of the frontal bone thickening - is often ignored and its nature and development are not yet understood sufficiently. Current macroscopic classification defines four grades/stages of HFI based on the morphological appearance and size of the affected area; however, it is unclear if these stages also depict the successive phases in the HFI development. Here we assessed 3D-microarchitecture of the frontal bone in women with various degrees of HFI expression and in an age- and sex-matched control group, hypothesizing that the bone microarchitecture bears imprints of the pathogenesis of HFI and may clarify the phases of its development. Frontal bone samples were collected during routine autopsies from 20 women with HFI (age: 69.9 +/- 11.1years) and 14 women without HFI (age: 74.1 +/- 9.7years). We classified the HFI samples into four groups, each group demonstrating different macroscopic type or stage of HFI. All samples were scanned by micro-computed tomography to evaluate 3D bone microarchitecture in the following regions of interest: total sample, outer table, diploe and inner table. Our results revealed that, compared to the control group, the women with HFI showed a significantly increased bone volume fraction in the region of diploe, along with significantly thicker and more plate-like shaped trabeculae and reduced trabecular separation and connectivity density. Moreover, the inner table of the frontal bone in women with HFI displayed significantly increased total porosity and mean pore diameter compared to controls. Microstructural reorganization of the frontal bone in women with HFI was also reflected in significantly higher porosity and lower bone volume fraction in the inner vs. outer table due to an increased number of pores larger than 100m. The individual comparisons between the control group and different macroscopic stages of HFI revealed significant differences only between the control group and the morphologically most pronounced type of HFI. Our microarchitectural findings demonstrated clear differences between the HFI and the control group in the region of diploe and the inner table. Macroscopic grades of HFI could not be distinguished at the level of bone microarchitecture and their consecutive nature cannot be supported. Rather, our study suggests that only two different types of HFI (moderate and severe HFI) have microstructural justification and should be considered further. It is essential to record HFI systematically in human postmortem subjects to provide more data on the mechanisms of its development.

AB  - It has been suggested that unerupted lower third molars (M3) increase the fragility of the mandibular angle and simultaneously decrease the risk of condylar fracture. However, it is unknown whether this applies regardless of the direction and point of impact of the traumatic force. The aim of this study was to investigate the impact of an unerupted M3 on the fragility of the angle and condyle in terms of a force acting from different directions and affecting different regions of the mandible. Computed tomography scans of a human mandible and finite element methodology were used to obtain two three-dimensional models: a model with, and the other without an unerupted M3. A force of 2000 N was applied to three different regions of the models: the symphysis, ipsilateral body, and contralateral body, respectively. When the force was applied to the mandibular body, the results revealed increased angle fragility in cases with unerupted M3. When the force was applied to the symphysis, the condyle region showed higher fragility, irrespective of the presence of an unerupted M3. In summary, fragility of the angle and condyle regions depends on the presence of an unerupted M3 and on the direction and point of impact of the force.

AB  - Endocranial bone lesions have attracted intensive scientific debate on their aetiology. In recent literature, the lesions were almost exclusively interpreted as of infectious origin. In this paper, we give new insight into the aetiology of endocranial lesions, distinguishing the lesions of vascular origin from those caused by tuberculosis or other conditions. The analysis is based on a rare case of a young female individual who displayed multiple endocranial lesions with ‘serpens endocrania symmetrica’ morphology. The lesions were associated with an uncommon branching pattern of the middle meningeal artery and marked side differences in teeth pathology. Postcranial skeleton showed signs of the left upper limb weakness. The macroscopic finding of the endocranial lesions along with the skeletal evidence of neurological damage, together with characteristic radiological and histological features, can lead to diagnosis of arteriovenous malformations. This study aims to improve understanding of the aetiology of endocranial bone lesions.

AB  - Understanding of the occlusal load distribution through the mid-facial skeleton in natural dentition is essential because alterations in magnitude and/or direction of occlusal forces may cause remarkable changes in cortical and trabecular bone structure. Previous analyses by strain gauge technique, photoelastic and, more recently, finite element (FE) methods provided no direct evidence for occlusal load distribution through the cortical and trabecular bone compartments individually. Therefore, we developed an improved three-dimensional FE model of the human skull in order to clarify the distribution of occlusal forces through the cortical and trabecular bone during habitual masticatory activities. Particular focus was placed on the load transfer through the anterior and posterior maxilla. The results were presented in von Mises stress (VMS) and the maximum principal stress, and compared to the reported FE and strain gauge data. Our qualitative stress analysis indicates that occlusal forces distribute through the mid-facial skeleton along five vertical and two horizontal buttresses. We demonstrated that cortical bone has a priority in the transfer of occlusal load in the anterior maxilla, whereas both cortical and trabecular bone in the posterior maxilla are equally involved in performing this task Observed site dependence of the occlusal load distribution may help clinicians in creating strategies for implantology and orthodontic treatments. Additionally, the magnitude of VMS in our model was significantly lower in comparison to previous FE models composed only of cortical bone. This finding suggests that both cortical and trabecular bone should be modeled whenever stress will be quantitatively analyzed.

AB  - The aim of the present study was to investigate the influences of the presence and position of a lower third molar (M3) on the fragility of mandibular angle and condyle, using finite element analysis. From computed tomographic scans of a human mandible with normally erupted M3, two additional virtual models were generated: a mandibular model with partially impacted M3 and a model without M3. Two cases of impact were considered: a frontal and a lateral blow. The results are based on the chromatic analysis of the distributed von Mises and principal stresses, and calculation of their failure indices. In the frontal blow, the angle region showed the highest stress in the case with partially impacted M3, and the condylar region in the case without M3. Compressive stresses were dominant but caused no failure. Tensile stresses were recorded in the retromolar areas, but caused failure only in the case with partially impacted M3. In the lateral blow, the stress concentrated at the point of impact, in the ipsilateral and contralateral angle and condylar regions. The highest stresses were recorded in the case with partially impacted M3. Tensile stresses caused the failure on the ipsilateral side, whereas compressive stresses on the contralateral side.

abstract = "The aim of the present study was to investigate the influences of the presence and position of a lower third molar (M3) on the fragility of mandibular angle and condyle, using finite element analysis. From computed tomographic scans of a human mandible with normally erupted M3, two additional virtual models were generated: a mandibular model with partially impacted M3 and a model without M3. Two cases of impact were considered: a frontal and a lateral blow. The results are based on the chromatic analysis of the distributed von Mises and principal stresses, and calculation of their failure indices. In the frontal blow, the angle region showed the highest stress in the case with partially impacted M3, and the condylar region in the case without M3. Compressive stresses were dominant but caused no failure. Tensile stresses were recorded in the retromolar areas, but caused failure only in the case with partially impacted M3. In the lateral blow, the stress concentrated at the point of impact, in the ipsilateral and contralateral angle and condylar regions. The highest stresses were recorded in the case with partially impacted M3. Tensile stresses caused the failure on the ipsilateral side, whereas compressive stresses on the contralateral side.",

AB  - Although the concept of the occlusal load transfer through the facial skeleton along the buttresses has been extensively studied, there has been no study to link microarchitecture of the mid-facial bones to the occlusal load distribution. The aim of this study was to analyze micro-structural properties of the mid-facial bones in relation to occlusal stress. The study was performed by combining the three-dimensional finite element analysis (3D FEA) and micro-computed tomography analysis (micro-CT). Clenching was simulated on the computer model of the adult male human skull which was also used as a source of bone specimens. After the PEA was run, stress was measured at the specific sites in cortical shell and trabecular bone of the model along and between the buttresses. From the corresponding sites on the skull, twenty-five cortical and thirteen cancellous bone specimens were harvested. The specimens were classified into high stress or low stress group based on the stress levels measured via the FEA. Micro-architecture of each specimen was assessed by micro-CT. In the high stress group, cortical bone showed a tendency toward greater thickness and density, lower porosity, and greater pore separation. Stress-related differences in microstructure between the groups were more pronounced in trabecular bone, which showed significantly greater bone volume fraction (BV/TV) and trabecular thickness (Tb.Th) in the high stress group. Our results suggest that the mid-facial bones in the adult dentate male skull exhibit regional variations in cortical and trabecular bone micro-architecture that could be a consequence of different occlusal

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.

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.

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.

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  - Uvod/Cilj. Radiokontrastnost jednog endodontskog materijala može znatno varirati u zavisnosti od toga da li je određivano na filmu ili digitalnim senzorom. Digitalna radiografija pruža mnogobrojne prednosti u odnosu na konvencionalnu radiografiju u svakodnevnoj stomatološkoj kliničkoj praksi, kako u pogledu dijagnostičkih mogućnosti, tako i u praćenju rezultata lečenja. Cilj ove studije bio je da se ispitaju mogućnost i konvencionalne i charge-conpled device (CCD) digitalne radiografije za vizualizaciju materijala na radiogramu u zavisnosti od kontrastnog sredstva prisutnog u materijalu. Metode. Eksperimentalni cementi su pripremljeni dodavanjem sledećih kontrastnih sredstava u Portland cement: cink-oksid (ZnO), cirkonijum-oksid (ZrO2), titanijum-dioksid (TiO2), barijum-sulfat (BaSO4), jodoform (CHI3), bizmut-oksid (Bi2O3) i iterbijum-trifluorid (YbF3). Takođe, ispitivano je pet kontrolnih endodontskih cementa: Endomethasone®, Diaket®, N2®, Roth 801® i Acroseal®. Po tri uzorka svakog materijala su radiografisana pored aluminijumskog stepeničastog etalona na filmu (Eastman Kodak Company, Rochester, NY) i CCD digitalnom senzoru (Trophy Radiologie, Cedex, France). Vrednosti rendgenkontrastnosti izračunavane su konverzijom radiografskih gustina uzoraka izraženih optičkim gustinama ili stepenom tona sivo-bele skale u odgovarajuću debljinu aluminijuma. Rezultati. Dvostrukom analizom varijanse nije ustanovljena statistički značajna razlika između primenjenih metoda radiografisanja (p > 0.05), ali su vrsta kontrastnog sredstva (p  lt  0.001) i interakcija ova dva faktora (p  lt  0.05) bili značajno različiti. Upareni t-test pokazao je statistički značajnu razliku između korišćenih metoda za čisti Portland cement, sve koncentracije BaSO4 i CHI3, 10% i 20% dodatka ZrO2 i Bi2O3 i 10% i 30% dodatka YbF3 (p  lt  0.05). Zaključak. Očekuje se da materijali koji sadrže CHI3 ili BaSO4 kao kontrastna sredstva budu lakše uočljivi na digitalnom senzoru nego na konvencionalnom dentalnom filmu. U kliničkom radu mora se imati u vidu kvalitet procene kontrasta koju pokazuje digitalna slika u odnosu na sliku dobijenu konvencionalnom radiografijom.

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., Uvod/Cilj. Radiokontrastnost jednog endodontskog materijala može znatno varirati u zavisnosti od toga da li je određivano na filmu ili digitalnim senzorom. Digitalna radiografija pruža mnogobrojne prednosti u odnosu na konvencionalnu radiografiju u svakodnevnoj stomatološkoj kliničkoj praksi, kako u pogledu dijagnostičkih mogućnosti, tako i u praćenju rezultata lečenja. Cilj ove studije bio je da se ispitaju mogućnost i konvencionalne i charge-conpled device (CCD) digitalne radiografije za vizualizaciju materijala na radiogramu u zavisnosti od kontrastnog sredstva prisutnog u materijalu. Metode. Eksperimentalni cementi su pripremljeni dodavanjem sledećih kontrastnih sredstava u Portland cement: cink-oksid (ZnO), cirkonijum-oksid (ZrO2), titanijum-dioksid (TiO2), barijum-sulfat (BaSO4), jodoform (CHI3), bizmut-oksid (Bi2O3) i iterbijum-trifluorid (YbF3). Takođe, ispitivano je pet kontrolnih endodontskih cementa: Endomethasone®, Diaket®, N2®, Roth 801® i Acroseal®. Po tri uzorka svakog materijala su radiografisana pored aluminijumskog stepeničastog etalona na filmu (Eastman Kodak Company, Rochester, NY) i CCD digitalnom senzoru (Trophy Radiologie, Cedex, France). Vrednosti rendgenkontrastnosti izračunavane su konverzijom radiografskih gustina uzoraka izraženih optičkim gustinama ili stepenom tona sivo-bele skale u odgovarajuću debljinu aluminijuma. Rezultati. Dvostrukom analizom varijanse nije ustanovljena statistički značajna razlika između primenjenih metoda radiografisanja (p > 0.05), ali su vrsta kontrastnog sredstva (p  lt  0.001) i interakcija ova dva faktora (p  lt  0.05) bili značajno različiti. Upareni t-test pokazao je statistički značajnu razliku između korišćenih metoda za čisti Portland cement, sve koncentracije BaSO4 i CHI3, 10% i 20% dodatka ZrO2 i Bi2O3 i 10% i 30% dodatka YbF3 (p  lt  0.05). Zaključak. Očekuje se da materijali koji sadrže CHI3 ili BaSO4 kao kontrastna sredstva budu lakše uočljivi na digitalnom senzoru nego na konvencionalnom dentalnom filmu. U kliničkom radu mora se imati u vidu kvalitet procene kontrasta koju pokazuje digitalna slika u odnosu na sliku dobijenu konvencionalnom radiografijom.",

AB  - Background: Developmental disturbances of the paranasal sinuses are proposed as the cause of osteoma. We examined whether such disturbances may result in the frequent presence of anatomical variations of the paranasal sinuses in patients with osteoma. Methodology/Principal: The study was performed retrospectively on 2,820 patients subjected to CT examination during 2005 - 2011. Demographic and CT characteristics of osteoma, and associated pathological findings were evaluated for 104 patients with diagnosed osteoma. The presence of anatomical variations was assessed for 51 osteoma patients with a complete medical history, and for 1,233 patients from a control group. Results: The prevalence of osteomas was found to be 3.69%, with male to female ratio 1.08:1. The frontal sinus was most commonly affected, The presence of anatomical variations was more frequent in patients with osteoma than in controls, with significant differences confirmed for the sphenomaxillary plate, infraorbital cell, and crista galli pneumatization. Conclusions: The paranasal sinus osteoma is associated with higher prevalence of anatomical variations, This can be explained either by the stronger influence of genetic and/or environmental factors on the development of the paranasal sinuses in patients with osteoma, or by their higher susceptibility to abovementioned factors.

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  - Osteoporoza jeste značajno i zastupljeno oboljenje kada dominiraju procesi razgrađivanja kostnih supstanci u humanim organizmima. Za razliku od činjenica da u literaturi postoje brojni prikazi – makroskopski patološki preparati, mikroskopski patološki preparati, šematizovane ilustracije itd. skoro da nema podataka ni o promenama fizičkih parametara, niti o uticajima kompleksnih hemijskih jedinjenja u kostnim supstancama izmenjenim usled osteoporoza na fizičko-hemijske osobenosti izmenjene kosti, tako da dosta toga još uvek nije ispitano u vezi karakteristika, izmena sastava i fizičko-hemijske osobenosti osteoporoznih kosti. (Kanis 1994; 1996, WHO 1994 Kršljak 1995, Novaković i Giordani 1996, Poštić, Marković, Veselinović Tijanić i Zec 2001). Svakako bi trebalo da bude interesantno i značajno proceniti šta je izmenjeno u makrostrukturama i šta je sve izmenjeno u mikrostrukturama kosti oštećenih usled osteoporoza. Čini se da je važno utvrditi kako bi trebalo delovati na nivou jedinjenja i potencijalno na nivou molekula. Stoga je potrebno ispitati kako bi, na osnovu izmena u mikrostrukturama kosti, trebalo inicirati pozitivno remodelovanje kostne supstance, da li su formirana jedinjenja kakva je potrebno razgraditi zato što su apsolutno nepovoljna ili je moguće delovati, bez obzira na formirana odnosno preformirana jedinjenja, apozicijama potrebnih i u smislu osteogenih potencijala kvalitetnih jedinjenja na nivoima mikrostruktura. Ispitivanjima fizičko-hemijskih promena mikrostruktura kosti trebalo bi da budu utvrđeni karakteristični podaci, tako da bi na osnovu karakterističnih podataka trebalo proceniti da li bi aplikovanjima posebno sintetisanih jedinjenja odnosno specifičnih supstanci i aplikovanjima posebno kombinovanih supstanci bilo moguće poboljšati strukture kosti, ojačati segmente kosti - poboljšati fizičko-hemijska svojstva i sprečiti frakture segmenata kosti.

Za razliku od činjenica da u literaturi postoje brojni prikazi – makroskopski patološki preparati, mikroskopski patološki preparati, šematizovane ilustracije itd. skoro da nema podataka ni o promenama fizičkih parametara, niti o uticajima kompleksnih hemijskih jedinjenja u kostnim supstancama izmenjenim usled osteoporoza na fizičko-hemijske osobenosti izmenjene kosti, tako da dosta toga još uvek nije ispitano u vezi karakteristika, izmena sastava i fizičko-hemijske osobenosti osteoporoznih kosti. (Kanis 1994; 1996, WHO 1994 Kršljak 1995, Novaković i Giordani 1996, Poštić, Marković, Veselinović Tijanić i Zec 2001). Svakako bi trebalo da bude interesantno i značajno proceniti šta je izmenjeno u makrostrukturama i šta je sve izmenjeno u mikrostrukturama kosti oštećenih usled osteoporoza. Čini se da je važno utvrditi kako bi trebalo delovati na nivou jedinjenja i potencijalno na nivou molekula. Stoga je potrebno ispitati kako bi, na osnovu izmena u mikrostrukturama kosti, trebalo inicirati pozitivno remodelovanje kostne supstance, da li su formirana jedinjenja kakva je potrebno razgraditi zato što su apsolutno nepovoljna ili je moguće delovati, bez obzira na formirana odnosno preformirana jedinjenja, apozicijama potrebnih i u smislu osteogenih potencijala kvalitetnih jedinjenja na nivoima mikrostruktura. Ispitivanjima fizičko-hemijskih promena mikrostruktura kosti trebalo bi da budu utvrđeni karakteristični podaci, tako da bi na osnovu karakterističnih podataka trebalo proceniti da li bi aplikovanjima posebno sintetisanih jedinjenja odnosno specifičnih supstanci i aplikovanjima posebno kombinovanih supstanci bilo moguće poboljšati strukture kosti, ojačati segmente kosti - poboljšati fizičko-hemijska svojstva i sprečiti frakture segmenata kosti.",
