Abstract
Background: The determination of sex and age is necessary in forensic practice and medico legal purposes. Mandible may play a vital role in sex estimation as it is the most dimorphic bone of skull that often recovered intact. In this respect, the availability of plentiful antemortem digital panoramic radiographs may be of great value in studying and developing population specific standards for accurate sex and age estimation. Aim of the work: The purpose of the current study was to assess the usefulness of six mandibular measurements in age estimation and sex identification in an Egyptian population sample using digital panoramic radiographs. Participants and Methods: By using digital panoramic radiographs,six mandibular dimensions were measuredin 200 Egyptian participants (103 females and 97 males) aged between 20-60 years. They were classified into 4 age groups; group 1 (20-29), group 2 (30-39), group 3 (40-49) and group 4 (50-60). The measured dimensions were the maximum ramus length, maximum ramus breadth, gonial angle, bigonial width, antegonial angle and antegonial depth. All these dimensions were measured on the right side except bigonial width. Data were analyzed using statistical software SPSS-24 and stepwise discriminant analysis and logistic regression analysis were performed to determine the most significant predictors for sex. Results: Comparison between the 4 age groups using ANOVA didn{u2019}t show statistically significant difference concerning the studied dimensions however, comparison between these groups in females and males separately showed statistically significant difference in some dimensions. Moreover, comparison between the right and left rami showed statistically significant difference in some dimensions. A statistically significant correlation existed between group 4 and age with no similar findings with other groups but some of them showed significant correlation within females and males separately. The measured dimensions showed statistically significant difference between males and females with higher male mean values in linear measurements and higher female mean values in angular measurementson equation into forensic field is recommended
