“…According to Samantha et al, 14 similar results were seen in corrsepondance to the present study where the condylar height was found to be significant and the mean values for males is 65.34mm and in females it was 61.69mm and the coronoid height plays no significant role which was in correlation with our study.…”

“…Similar findings were noticed in a study done by Sairam et al, 13 comparing the different mandibular measurements, the condylar height was found to be significant in gender determination with mean in males and females being 65.01mm and 59.48mm on right side and 65.71mm and 59.65mm on left side. According to Samantha et al, 14 similar results were seen in corrsepondance to the present study where the condylar height was found to be significant and the mean values for males is 65.34mm and in females it was 61.69mm. In a study done by Saraswathi G et al, 15 using CBCT images of 50 males and 50 females with a mean condylar height in males was 65.79mm and in females was 61.80mm thus concluded that the height of the condyle can be the best parameter.…”

Introduction:The determination of age and gender in remnants of skull is important for medico-legal cases, especially where the bodies have been injured beyond identification as seen usually in cases of mass disaster. Panoramic radiographs are frequently used in routine dental practice to visualize the complete maxillo-mandibular region, temporo-mandibular joint and bilateral vital structures which are recorded on a single film. Hence, using digital panoramic radiographs this study was conducted in Telangana population to evaluate the usefulness of different linear measurements of ramus in determination of age and gender. Materials and Methods: 150 panoramic images of dentate subjects with an age ranging from 20-70yrs old were selected for the present study. For every panoramic image measurements were performed bilaterally resulting in a total of 300 rami being assessed. The digital panoramic images were saved in JPEG. File format and exported to the Care stream dental imaging software where the linear measurements were performed. The measurements were made using condylar-ramus and coronoid-ramus height. These measurements were subjected to statistical analysis. Results: It was seen that the Condyle to Gonion (CG) and Coronoid to Gonion (CoG) values is greater in males than in females with high significance. On comparison of the mean values of CG and CoG amongst the 3 age groups there was a significant difference in the mean CG values but not in the mean CoG values. Conclusion:The ramus height measurements on digital panoramic radiogrpahs can be used in the determination of age and gender.

“…In a previous study, the greatest sexual dimorphism was at the maximum ramus height [27] in accordance with the results of Schultze et al, [12] and Kambylafkas et al, [28] which assured that mandibular ramus showed differences between the sexes more than mandibular body. Similar results were reported by Samatha et al, [29] as the projective height of ramus showed the highest sexual dimorphism and least was seen with minimum ramus breadth. Projective height of ramus, maximum ramus breadth and condylar height was statistically significant.…”

Background: Determination of the sex is an important step in the identification of skeletal remains especially in missing persons and mass disasters. Mandible, being a strong bone that is difficult to damage and disintegrate, is an important tool in sex determination. Aim of the Study: The present study aimed to evaluate accuracy of mandibular metric standards for estimating sexual dimorphism. Methods: The study was conducted on 90 males and 92 females of Egyptian sample. Orthopantomographs were taken for evaluating eleven mandibular metric parameters. Four models were adopted by the stepwise discriminant analysis test to define the best predictor of sex discrimination in the Egyptian population sample. Results: All parameters were found to be significantly different between both sexes; and the most dimorphic parameters were coronoid height, projective height, and mandibular canal length, followed by mandibular notch depth and condylar height. Meanwhile the least variables were gonial angle and bicondylar length. Conclusion: This study proves that mandibular measurements on digital radiograph are useful in sex determination.

“…1,2 Thus, the part of skull such as mandible can have high diagnostic value. 5 The mandible itself is a large and very strong bone from the skull, therefore it is used for analysis. Basically, men bones are bigger and strong than women, because the shape, strength and angulation of the masticatory muscles affect the expression of mandibular dimorphism, because the degree of use of these muscles varies in men and women.…”

Background : Identification of personal is one of important aspects in forensic odontology, because it is one of the core aspect of forensic science. The one methode of sex determination is measurement of mandibular. The mandibular is a largest and most powerful facial bone in the skull, which is generally resistant to postmortem damage and an important source for personal identification. Previous studies have studied gender and age prediction using CBCT reconstructive images in a different picture.The objective of this study is to determine the sex determination of os.mandibular using CBCT anthropometric measurements.Materials and Methods : This study involved twenty subjects (10 male and 10 female) with age group between 20 and 35 years. CBCT scans were performed on all subjects, and the data obtained is reconstructed for 3D viewing. After getting a 3D CBCT scan, measurements were taken on six parameters.Results : The differential mean of male and female is 1,7 mm (Ramus-L), 2,1 mm (Con-Cor), 6,9 mm (BG-Br), 7,3 mm (BIC-Br), 3,5 mm (BH 1st molar) dan 3,8 mm (BH canine). The collected data were analyzed using SPSS statistical with Independent T-Test and Logistic Regression test and also Discrimant Function. The results showed that of the six parameters, BG-Br and BIC-Br showed 0,0 (P<0,05) statistically significant differences, with the accuracy of the prediction of gender determination on BIC-Br 70% for male and 80% for female and the overall BG-Br yield of 80% to both group. Conclusion : Sex determination using mandibular with 3D imaging methods can be used and helps in sex determination with 80% accuracy.
