Abstract

Background: Mandible is a unique single bone often recovered intact during mass disasters.
Aims: To assess whether the specific morphological characteristics of mandible in males and females can be used as an aid for sex determination based on radiographs.
Materials and Methods: A two-year retrospective study was conducted in 200 subjects [100 males and 100 females] using digital radiographs. Profile of chin and morphologic differences in the base of the mandible were assessed using digital lateral cephalogram. Mandibular ramus flexure was assessed from digital Orthopantomogram. The obtained data statistically analysed using SPSS software version 20. Descriptive statistics was analysed. Chi square test was done to determine the association between gender and different parameters. The level of significance set at p < 0.05.
Results: There is a significant association between chin profile, base of mandible and mandibular ramus flexure with gender. Females have prominent chin compared to males. Males have undulating base of mandible while females have straight base of mandible. Mandibular ramus flexure in males seen at the level of occlusal plane while it is seen above the occlusal plane in females.
Conclusion: There is a morphological difference in the mandible of the males and females.

Keywords: Morphology, Digital radiography, Chin profile, Ramus flexure.
