Abstract

BACKGROUND

Palatal rugae are asymmetric and irregular ridges on the anterior palatal region, which have proven to be useful in the field of forensic dentistry. This study aims to use morphological analysis of palatal rugae patterns to assess sex in a South Indian adult population.

MATERIALS AND METHODS

This cross-sectional study was undertaken to evaluate a total of 300 maxillary dental casts (150 males and 150 females). The rugae patterns were marked by one observer and classified as per Thomas and Kotze criteria by another observer. The rugae patterns were classified based on the total number of rugae, shape, predominant direction of rugae, and unification of rugae.

RESULTS

The palatal rugae in female participants showed a higher incidence of circular rugae and backward directed rugae, while male participants showed more forward-directed rugae. The logistic regression analysis showed a significant association of with circular (OR=1.48; 95% CI= 1.02-2.13), forward (OR=0.87; 95% CI= 0.78-0.97) and backward (OR=1.23; 95% CI= 1.08-1.41) palatal rugae with sex.

CONCLUSION

Certain palatal rugae patterns can be used for the assessment of sex with limited accuracy.

摘要

背景

腭皱襞是腭前部区域不对称且不规则的嵴，已证实在法医牙科学领域有用。本研究旨在利用腭皱襞形态分析评估南印度成年人群的性别。

材料与方法

本横断面研究共评估300副上颌牙模型（150名男性和150名女性）。一名观察者标记皱襞形态，另一名观察者根据托马斯和科策标准进行分类。根据皱襞总数、形状、皱襞主要方向和皱襞融合情况对皱襞形态进行分类。

结果

女性参与者的腭皱襞中圆形皱襞和向后的皱襞发生率较高，而男性参与者的向前的皱襞较多。逻辑回归分析显示圆形（比值比=1.48；95%置信区间=1.02 - 2.13）、向前（比值比=0.87；95%置信区间=0.78 - 0.97）和向后（比值比=1.23；95%置信区间=1.08 - 1.41）腭皱襞与性别存在显著关联。
