Gender determination by radiographic analysis of mental foramen in the Maharashtra population of India

SummaryBackground/Aim: Gender determination is one of the most challenging tasks in medico-legal research and forensic dentistry. Several skeletal components are investigated for this purpose and the mandible is one of them. The mandible has several specific anatomical features. The purpose of this study was to analyze the effects of measurements related to the mental foramen, gonial angle and antegonial angle on gender determination using digital panoramic radiographs.Material and Methods: A retrospective study was planned with 150 digital panoramic radiographs (75 males and 75 females, aged between 20 to 49 years). The radiographs were analyzed by dividing them into two equal gender groups (male and female). Several parameters were compared to determine the gender. The distances from the superior and inferior border of the mental foramen to the basis of the mandible on the right side were measured. Gonial and antegonial angles were evaluated bilaterally. The difference between the males and females were analyzed with independent samples t-test (p<0.05).Results: There was statistically significant difference between the males and females in terms of all the evaluated parameters (p<0.05). The distances related to mental foramen is higher in the males however gonial and antegonial angles are larger in the females.Conclusions: The mental foramen position, gonial and antegonial angles can be used to predict the gender in Turkish population.

AIM: The present study aimed at evaluating the role of mental foramen and mandibular canal in gender determination using CBCT.METHODOLOGY: A total number of 73 volumes of CBCT of the mandible was evaluated. Four measurements were used to assess the bucco-lingual and supero-inferior location of mandibular canal and the supero-inferior location of mental foramen was determined using two measurements on both right and left sides of the mandible. Inter and intra-observer variability was analyzed with help of t-test.RESULTS: Good intra-observer and inter-observer agreement was noted with regard to all the six measurements. The mean of all the measurements of mental nerve foramen and mandibular canal was found to be higher in males than females, however, significant difference was noted with regard to Superior Mental foramen (SMeF) and Superior Inferior Alveolar Canal (SMC) (p=0.037, p<0.001 respectively) on the right side and SIAC and Inferior Inferior Alveolar Canal (IIAC), (p=0.015, p=0.046 respectively) on the left side.CONCLUSION: The results of the present study suggest that SMeF, SIAC and IIAC may be used for gender determination. Further, either side of mandible can be used for this purpose. CBCT was found to be a useful modality in this study for sexual dimorphism.
