Abstract
Background: Gender determination is an important part of forensic dentistry and legal investigations. Mandible is the largest, sexually dimorphic, and strongest bone of the facial skeleton. Morphometric measurements of the mandible by using orthopantomogram are widely used in gender determination.
Aim: The aim of this study was to determine the efficacy of minimum ramus breath and coronoid height of the mandible for gender determination using orthopantomogram.
Materials and methods: Sixty orthopantomograms of 30 males and 30 females between the age group of 30 to 40 years were collected. The minimum ramus breath and the coronoid height were measured using a computerized software. The data obtained was statistically analysed using IBM SPSS Statistics for Windows, Version 23.0 (IBM Corp., Armonk, New York, United States) software.
Results: The mean minimal ramus breath and mean coronoid height were greater in males than in females. The mean minimal ramus breath for males was found to be 37.83 ± 2.24 and for females, it was 33.08 ± 4.87 (P = 0.00). The mean coronoid height of males was 80.67 ± 0.83 and that of females was 73.51 ± 1.26 (P = 0.00).
Conclusion: Our results suggest that the mandible is a sexually dimorphic bone, and the minimum ramus breath and coronoid height can be used in gender determination. However, population specific studies with larger sample sizes are recommended.
背景:性别鉴定是法医牙科和法律调查的重要组成部分。下颌骨是面部骨骼中最大、两性二态、最强壮的骨骼。下颌骨的形态测量是一种广泛应用于性别鉴定的方法。目的:本研究的目的是确定下颌最小分支呼吸和冠状高度在骨断层成像中用于性别确定的有效性。材料与方法:收集30 ~ 40岁男性30例,女性30例,共60例。用计算机软件测量最小分支呼吸和冠状高度。使用IBM SPSS Statistics for Windows, Version 23.0 (IBM Corp., Armonk, New York, United States)软件对所得数据进行统计分析。结果:男性的平均最小支呼吸量和平均冠状高度均大于女性。男性平均最小支息为37.83±2.24,女性平均最小支息为33.08±4.87 (P = 0.00)。男性平均冠高为80.67±0.83,女性平均冠高为73.51±1.26 (P = 0.00)。结论:下颌骨是一种性别二形骨,最小支息和冠高度可作为性别鉴定的依据。然而,建议进行更大样本量的特定人群研究。
期刊介绍:
The journal of Oral and Maxillofacial Pathology [ISSN:print-(0973-029X, online-1998-393X)] is a tri-annual journal published on behalf of “The Indian Association of Oral and Maxillofacial Pathologists” (IAOMP). The publication of JOMFP was started in the year 1993. The journal publishes papers on a wide spectrum of topics associated with the scope of Oral and Maxillofacial Pathology, also, ensuring scientific merit and quality. It is a comprehensive reading material for the professionals who want to upgrade their diagnostic skills in Oral Diseases; allows exposure to newer topics and methods of research in the Oral-facial Tissues and Pathology. New features allow an open minded thinking and approach to various pathologies. It also encourages authors to showcase quality work done by them and to compile relevant cases which are diagnostically challenging. The Journal takes pride in maintaining the quality of articles and photomicrographs.
