The aim of this study was to identify and compare the rugae pattern between males and females of two different communities in the city of Davangere, Karnataka, India, which may be an additional method of identification in cases of crimes or communal riots. Elastomeric impressions of the maxillary arch of 100 selected children were made; casts were poured in Type IV stone. The method of identification of rugae pattern followed was that of Lysell and Thomas and Kotze, which includes the number, shape, direction, and unification of rugae. The study revealed no significant difference in the total number or length of rugae between the two communities and sexes. However, with regard to shape and unification, females showed a significantly higher diverging rugae type while males had a significant number of circular and converging type of rugae. Also, discrimination function analysis allowed a moderate differentiation of the population. Hence, the rugae pattern can be an additional method of differentiation in conjunction with the other methods such as visual, fingerprints, and dental characteristics in forensic sciences.
本研究的目的是识别和比较印度卡纳塔克邦达万盖尔市两个不同社区男性和女性的腭皱襞模式，这可能是犯罪或群体骚乱案件中一种额外的身份识别方法。对100名选定儿童的上颌牙弓制作了弹性印模；用IV型石膏灌制模型。所采用的腭皱襞模式识别方法是Lysell、Thomas和Kotze的方法，包括皱襞的数量、形状、方向和融合情况。研究表明，两个社区以及不同性别之间，腭皱襞的总数或长度没有显著差异。然而，在形状和融合方面，女性的发散型皱襞类型显著更多，而男性则有大量圆形和汇聚型皱襞。此外，判别函数分析能够对人群进行适度区分。因此，腭皱襞模式可以作为法医学中与视觉、指纹和牙齿特征等其他方法相结合的一种额外的区分方法。
