Forensic odontology plays a pivotal role in identifying individuals in legal contexts. This study analyses the efficacy of lip prints, tongue prints and mandibular canine width in determining gender, aiming to contribute to the evolving field of forensic dentistry.
A cross-sectional study was conducted involving 100 participants, analysing lip prints based on Tsuchihashi's classification, recording tongue shapes and features through the use of alginate impressions and measuring mandibular canine width using a vernier calliper. The findings were reported in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology checklist.
In lip prints, Tsuchihashi's Type I lip print was predominantly found in females, whereas Tsuchihashi's Type III prevailed in males. Tongue shapes revealed a predominance of pentagonal shapes in males and ovoid shapes in females. The lingual apex was blunt in males and sharp in females. Mandibular canine width was higher in males than females on both the left and right sides.
The findings of this study support the use of lip prints, tongue prints and canine width in determining gender as ancillary and supporting methods.
法医牙科学在法律背景下识别个体方面发挥着关键作用。本研究分析了唇纹、舌纹和下颌尖牙宽度在确定性别方面的功效，旨在为不断发展的法医牙科学领域做出贡献。
进行了一项横断面研究，涉及100名参与者，根据土桥分类法分析唇纹，通过使用藻酸盐印模记录舌的形状和特征，并使用游标卡尺测量下颌尖牙宽度。研究结果按照《加强流行病学观察性研究报告规范》清单进行报告。
在唇纹方面，土桥I型唇纹主要见于女性，而土桥III型在男性中占主导。舌的形状显示男性中五角形居多，女性中卵形居多。男性的舌尖钝，女性的舌尖尖。左右两侧男性的下颌尖牙宽度均高于女性。
本研究结果支持将唇纹、舌纹和尖牙宽度作为确定性别的辅助和支持方法。
