The aim of this study was to identify and compare the different morphological rugae patterns in males and females of western Indian population, which may be an additional method of identification in cases of crimes or aircraft accidents. A total of 108 plaster casts, equally distributed between the sexes and belonging to similar age-group, were examined for different biometric characteristics of the palatal rugae including number, shape, length, direction and unification and their incidence recorded. Association between these rugae biometric characteristics and sex were tested using chi-square analysis and statistical descriptors were identified for each of these parameters using the SPSS 15.0. The study revealed a statistically significant difference in the total number of rugae between the two sexes (P = 0.000). The different types of rugae between the males and females were statistically compared. The female showed a highly significant difference in the sinuous (P = 0.002) and primary type (P = 0.000) while the male had a significant difference in the unification (P = 0.005). The predominant direction of the rugae was found to be forward relative to backward. It may be concluded that the rugae pattern can be an additional method of differentiation between the male and female 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西部人群中男性和女性不同的腭皱襞形态模式，这可能是犯罪案件或飞机事故中一种额外的身份识别方法。共检查了108个石膏模型，这些模型在性别上平均分布且属于相似年龄组，以研究腭皱襞的不同生物特征，包括数量、形状、长度、方向和融合情况，并记录其发生率。使用卡方分析测试这些皱襞生物特征与性别的关联性，并使用SPSS 15.0为每个参数确定统计描述符。研究显示，两性之间的皱襞总数存在统计学上的显著差异（P = 0.000）。对男性和女性之间不同类型的皱襞进行了统计学比较。女性在蜿蜒型（P = 0.002）和原始型（P = 0.000）上显示出高度显著差异，而男性在融合型上有显著差异（P = 0.005）。发现皱襞的主要方向是向前而非向后。可以得出结论，在法医学中，结合视觉、指纹和牙齿特征等其他方法，皱襞模式可以成为区分男性和女性的一种额外方法。
