The International Agency for Research on Cancer (IARC) has classified the electromagnetic fields emitted from mobile phone devices as group 2b, i.e. “maybe being carcinogenic to humans”. Objectives: The aim of present study was to investigate the potential effects of microwave radiation on the proliferation activity of parotid gland by measuring Ki-67 protein levels. Material and methods: Sixteen male adult New Zealand white rabbits were divided fifty-fifty into control and experimental groups. The experimental group was exposed to the radiation one hour daily, six days every week for 6 months. The rabbits were sacrificed according to ethical methods and parotid glands were removed after the exposure period has ended; so, sixteen biopsies stained with monoclonal antibody Ki-67 were obtained. The method of calculating the percentage of immunopositive cells from the total c...

The teeth were restored with resin modified glass ionomer cement and stainless-steel crowns. All teeth were assessed clinically and radiographically for success and followed at 3, 6 and 12 months. Results: At 12 months follow-up, the Clinical success rates of MTA and PC were 100% and 93.3% respectively. The radiographic success rate of MTA after 12 months was 96.7% while PC was 93.3% respectively. However, the results showed no significant difference between the two groups. Conclusion: This study finding showed that PC can be used a as pulpotomy agent with high clinical and radiographic success rates similar to MTA. PC may serve as a good alternative to MTA for pulpotomies of primary teeth.

The sample consisted of 160 CT scans collected from a Brazilian population (74 males, 86 females) aged 18-60 years. The CBCT images were analyzed by five reviewers. Six measurements (ramus length, gonion-gnathion length, minimum ramus breadth, gonial angle, bicondylar breadth, and bigonial breadth) were collected for the sexual prediction analysis. For the statistical analysis, intraclass correlation was used to evaluate intra-and inter-reviewers, analysis of variance was used to compare the mean values of these measurements, binary logistic regression equations were created to predicts sex. Using these four variables, the rate of correct sex classification was 95.1%. After, the discriminant function was used to validate the formula built. Accuracy of 93.33% and 94.74% was found for estimating male and females, respectively. Thus, the formula developed in this study can be used for sex estimation in forensic settings.

Case presentation A case of unknown skeletonized remains is reported in this investigation, which was found in a mass grave in Damascus Countryside governorate, Syria, in 2017. The post-mortem (PM) examination of bones and teeth was completed in al-Muwasat University Hospital in Damascus. Skull and pelvic bones showed Caucasoid male traits: the fourth rib and teeth examination estimated the age to be between 30 and 40 years, and the long bone estimated the stature in centimeters to be between 172 and 179. Intact dentition with tiny fracture in the incisal edge of the upper right central incisor—along with pathological fracture of right patella—was noted. Matching with ante-mortem (AM) smile photograph and radiograph of the right knee led to positive identification. Conclusions The present study highlights the importance...

Material and Methods: The sample consisted of 99 CBCT scans of the Syrian population (43 males, 56 females) aged between 18-25 years. The collected CBCT images were analyzed on two occasions and by two examiners to test the reliability of measurements. Four measurements were analyzed to be used for sexual prediction analysis as following: Coronoid-Gonion length (the distance between Gonion and the highest lateral point on the Coronoid process (, minimum ramus breadth, Gonial angle, and Bigonial width. Results: All the aforementioned measurements showed significant statistical sex-related differences. The Bigonial width showed the highest difference with (P < 0.01 _ mean: 95.17 ± 6.45 mm for males, 86.84 ± 4.81 mm for females), followed by the gonial angle (P<0.01_ mean: 127.11o ± 7.87o for males, 131.52o ± 6.08o for females). Coronoid-gonion length (P < 0.01 _ mean: 58.61 ± 6.78 mm for males, 53.97 ± 5.26 mm for females) and minimum ramus breadth (P < 0.01 _ mean: 29.63 ± 2.90 mm for males, 27.89 ± 2.73 mm for females). specificity and sensitivity for the four indices derived function were 79 % and 80 % respectively and the diagnostic accuracy was 79.6 %. Conclusions: The present study suggested that the sex of mandible in Syrian population could be assessed using metrical and angular measurements which considered as an additional tool for sex identification.
