Palatal rugae are irregular, asymmetric ridges of the mucous membrane extending laterally from the incisive papilla and the anterior part of the palatal raphe. The uniqueness and the overall stability of palatal rugae suggest their use for forensic identification.
The purpose of this study was to compare the palatal rugae patterns in 2 different populations in India (Madhya Pradesh and Kerala), and furthermore, to assess the predominant pattern if any in the selected groups.
60 maxillary study models (30 from each group) were examined in the age group ranging from 17 to 23 years. Palatal rugae pattern were examined in both the sexes on right and left sides of the palate for the total number (quantitative), length, shape, and predominant direction (qualitative).
After analyzing the rugae patterns in both the groups and between the 2 sides of the palate, the wavy pattern was found to be predominant followed by curved, straight, unification, circular, and nonspecific in decreasing order in the overall population.
Straight rugae pattern on the right side of the palate in the male subjects was found to be significantly predominant in the MP population, whereas wavy shape was predominant in Keralites; however, rugae patterns on the right side of the palate in female subjects exhibited no significant difference.
腭皱襞是从切牙乳头和腭中缝前部向外侧延伸的不规则、不对称的黏膜嵴。腭皱襞的独特性和整体稳定性表明其可用于法医鉴定。
本研究的目的是比较印度两个不同人群（中央邦和喀拉拉邦）的腭皱襞模式，此外，评估所选组中是否存在主要模式。
对60个上颌研究模型（每组30个）进行检查，年龄范围为17至23岁。对腭两侧的男女腭皱襞模式进行检查，包括总数（定量）、长度、形状和主要方向（定性）。
在分析两组以及腭两侧的皱襞模式后，发现波浪形模式在总体人群中占主导地位，其次是弯曲形、直线形、联合形、圆形和非特异性形，顺序递减。
在中央邦人群中，男性受试者腭右侧的直线形皱襞模式显著占主导地位，而喀拉拉邦人群中波浪形占主导地位；然而，女性受试者腭右侧的皱襞模式没有显著差异。
