Assessment of Diagnostic Quality and Acceptance of Bitewing Radiography Using Film Holder and Loop in 6-8 Year Old Children
Introduction: Bite wing radiographs are indicated in children with closed posterior contacts. Given the fact that nowadays bitewing radiographs are taken using both paper loop and film holder, the aim of this study is the evaluation of acceptance and diagnostic quality of two methods.
Materials and Methods: This study is a sort of diagnostic accuracy test that was performed on 20 6-8 year old children referring to Babol Dental School. Forty posterior bitewing radiographs were taken including 20 radiographs using film holder and 20 radiographs using paper loop. Di-agnostic quality of radiographs was assessed ac-cording to the film coverage, proximal overlap and observation of alveolar bone crest. Accep-tance was evaluated according to the feeling expressed by children about the radiographic experience. Data was processed by SPSS statistical software and McNemar test.
Results: Film coverage, proximal overlap and observation of alveolar bone crest were acceptable in all radiographs taken by film holder. Film coverage and observation of alveolar bone crest in upper second primary molar were acceptable in 70% and 65% of the radiographs taken by paper loop respectively that were significantly different with film holder group (P<0.05). There was no significant difference in the acceptance of the methods.
Conclusion: Bitewing radiograph with film holder produced adequate radiographs for almost all parameters and was well tolerated by children.

Mandibular Dimensional Changes with aging in Three Dimensional Computed Tomographic Study in 21 to 50 Year old Men and Women
Introduction: Raising the knowledge of skeletal and soft tissue changes with aging has been highly essential due to an increasing demand for aesthetic facial surgery following aging. The aim of this study is to evaluate the three dimensional computed tomographic images and process of changes in mandible with aging.
Materials and Methods: In this descriptive study, the facial CT scans were obtained from 124 subjects (70 men and 54 women). The population of the study was categorized in three ages (21 to 30, 31 to 40, 41 to 50). Each CT image was reinforced under volume rendering three-dimensional reconstruction by using the three dimensional analysis software volume viewer. The specific parts of mandible consisting of bigonial width, mandibular body height, ramus breadth, ramus height, mandibular body length and mandibular angle were measured and the data were analyzed employing two-ways analysis of variance.
Results: In both genders, there was no significant changes in bigonial width with aging (P=0.88). Mandibular body height for both genders decreased with aging but the result was not statistically significant (P=0.19). Ramus breadth decreased with aging in both genders (P=0.02).Considering the obtained means, ramus height and mandibular body length did not show significant changes in different age categories (P=0.09) (P=0.54). In both genders mandibular angle increased with aging (P=0.17).
Conclusion: Mandibular angle in women is greater than men and also for ramus breadth. There is no significant difference between men and women.

Oral and Systemic Conditions in Elderly Population Groups in Talash, North of Iran
Introduction: This survey was undertaken to assess self-reported oral health behaviour, oral and systemic conditions among functionally independent population in Talash, North of Iran. The question is whether there are any relationships between these variables. Materials and Methods: A total of 203 elderly subjects enrolled in this study 125 (61.5%) were males and 78 (38.4%) were females. All subjects were interviewed, dentally and orally examined. Demographics data,medical back-ground, oral hygiene practices and oral condi-tions were noted. Results: from total, 78.8% were edentulous and 86.7% had different oral conditions. The mean number of retained teeth was 7.34± 4. The most common oral conditions were dry mouth (41.9%), fissure tongue (30.5%), burning mouth (28.6%) and denture induced stomatitis (28.1%) respectively. Oral conditions were more prevalent in females than in males (Odds Ratio: 2.42, 95%CI0.93-6.28). Diabetes (OR: 6.22, 95%CI 0.816- 47.49) and hypertension (OR: 2.59, 95%CI 0.834-8.07) impact and deteriorate oral lesions. Life without systemic diseases giving rise to maintain more teeth (OR: 3.43, 95%CI 1.71-6.89). Oral diseases were more prevalent in uneducated people (OR: 2.67, 95%CI 0.948-7.5). Reported oral hygiene behaviour showed a significant relationship with oral lesions (OR: 5.25, CI95%: 1.82 -15.0, p<0.004). Conclusion: according to highly prevalence of oral diseases routine oral examinations should be advised

The Effect of Standard and Extended Curing Time in Different Distances on Composite’s Degree of Conversion
Introduction: The aim of this study was to in-vestigate the effect of irradiation duration and distance of light tip to prepared samples in two different light curing unites on the degree of conversion of resin composite. Materials and Methods: Conventional halogen and blue Light emitting diode (LED) units were used for polymerization of an Opalis resin com-posite. The conversion measurements were carried out at 0 and 8 mm distance from the directly irradiated surface in manufactured recommended curing time as well as in doubled curing time. The curing efficiency was observed with FTIR (Fourier transform infrared spectroscopy). Data was analyzed using ANOVA and Tukey post hoc test. Results: The LED curing unit exhibited the most homogenous in-depth curing efficiency at the same time (20 sec). The most amount of con-version degree in LED group was related to dis-tance 0 and irradiation time of 20 sec. However, in halogen groups the highest grade was observed in distance 0 and exposure time of 40sec. With increasing the distance between light guide tip and resin composite to 8 mm, being inevitable especially in class 2 box filling Conclusion: The result of our study confirmed that the best result for each group obtained in maximum contact with light source meanwhile reduplicating the manufacture recommended exposure time. Besides, in our research, LED showed a better outcome in proposed time of 20 sec in both distances.

Multiple Central Giant Cell Granuloma of the Mandible: A Case Report
Introduction: Central giant cell granuloma is a benign lesion but sometimes has aggressive proliferation composed of multinucleated giant cells in a background of spindle and ovoid mesenchymal cells. Multifocal central giant cell granuloma of jaws is very rare and usually associated with hyperparathyroidism and some syndromes. We described an un-usual case of a 22-year-old man with idi-opathic multiple central giant cell granuloma of mandible without significant clinical find-ings. The parathyroid hormone level, calcium and phosphorus inorganic were in normal limit. Patient had no familial history and clinical characteristic of Cherubism, Noonan-like syndrome and neurofibromatosis. This article refers to the fact that multiple central giant cell granuloma may be associated with no signs of systemic or specific syndromes and it can be an independent and idiopathic disease.

Maxillary Non-ossifying Fibroma: A Case Report and Review of the Literature
Introduction: Non-ossifying Fibroma (NOF) is a relatively common benign and non-neoplastic lesion in long bones of children and adolescents. As far as very few cases of NOF have been reported in jaws and what was managed to be found regarding all reported cases having occurred only in the mandible, in this article we are going to report a case of maxillary NOF in a 38-year-old female.
