Context: Gender determination is an important component of personal identification. Aims: Assessment of gender using mandible with Cone Beam Computed Tomography (CBCT). Settings and Design: This cross-sectional prospective study was conducted on dental outpatients in the department of Oral Medicine and Radiology. Methods and Material: 148 dental outpatients were selected and subjected to CBCT. Mandibular landmarks such as gonial angle, alveolar ridge to mental foramen distance, mental foramen to the inferior border of mandible distance, mandibular canal to the most anterior tangent point of buccal and lingual mandibular plate distance, mandibular canal border to the lowest tangent point on the inferior border of the mandible, coronoid height, bigonial breadth, minimal ramus breadth and ramus length were assessed on CBCT scan. Statistical Analysis Used: Data was represented as mean and Standard Deviation (SD). Parameters were compared between males and females using Kruskal-Wallis and Student’s independent T-test. A value below 0.05 represented significant results. Results: All parameters except gonial were significantly higher in males as compared to females angle (P< 0.05). The distance from the lowest point of the mandibular canal to the most posterior tangent point of the Mandibular Lingual Plate (MCLM) and bigonial breadth was higher in males than females but the difference was non-significant (P>0.05). The accuracy of CBCT was found to be 89.7% in males and 88.5% in females. Conclusions: Gender determination by morphometric analysis of the mandible using cone beam computed tomography is an effective method and provides higher accuracy as compared to two-dimensional conventional radiographs.

BACKGROUND: Identification and determination of gender of unknown human skeletal remains has been one of the most challenging tasks for forensic dentistry. AIM OF THE STUDY: The purpose of this study is to assess the role of cone beam computed tomography (CBCT) in gender determination through the measurements of the location of the mental foramen in in a sample of the Egyptian population. MATERIALS AND METHODS: Two measurements were performed in 200 CBCT images 2 measurements were performed; distance from the upper border of mental foramen to the lower border of the mandible and distance from the lower border of mental foramen to the lower border of the mandible in the right side of each CBCT image. Obtained data were statistically analyzed using t-test to compare between the two genders. RESULTS: The two measurements were significantly higher in males.

Introduction: this study aimed at determining gender and age by mandibular anatomy landmarks in computed tomography with Cone-Beam (CBCT). Methodology: this cross sectional study was performed on 147 CBCT images available in archive of radiology in the dentistry department of Ahvaz Jondi Shapoor medical science university. In this research, we assessed parameters including SMEF: Distance from mental foramen to the highest point of alveolar crest ridge, BIAC: distance from lowest point of IAC to the most anterior tangent point of buccal mandibular plate, LIAC: distance from the lowest IAC point to the most posterior tangent point o mandibular lingual plate, IMEF: distance from the lowest mental hole border to the lowest tangent point on inferior mandibular border, D2: distance from the lowest IAC canal border to the lowest tangent point on inferior mandibular border and gonial angle: junction of inferior mandibular border and posterior ramus border. Data were analysed by SPSS software 20th version and Spearman correlation coefficient tests, one-way variance analysis, Kruskal-Wallis, independent t, and Uman Withney. Results: SMEF level was significantly different in groups and in 25-34 group it was significantly higher than under 25 group. In right side it was significantly higher than female. IMEF had no significant difference in age groups and in both side it was higher in male than female. BIAC in both sides had no significant difference. LIAC in both sides an in different ages had no significant difference in male and female. D2 had no significant difference in both sides. But in a group with patients older than 55 it was significantly higher than 45-54 group. In addition, in left side it was higher in male than female there was no significant difference in gonial angle in different groups in left side with in right side there was significant difference in different age groups. But there was no significant difference in gender. Conclusion: evaluated indices in this research are not ry accurate to forecast age and gender and they cannot be used as accurate tools in estimating age and gender of people.
