Palatorugoscopy is the term used to study the rugae patterns. The word rugae came from the Greek word seam. Moreover, it relates the crisscrossing or joining or stitching of the parts of two biological structures during fetal differentiation. The aim of this study is to determine the gender difference in rugae pattern with regard to length, number, shape, unification and direction in the population of Sri Ganganagar, Rajasthan.
The objective is to determine the gender difference in rugae pattern with regard to length, number, shape, unification and direction; to investigate the difference in division of rugae in males and females and to compare rugae pattern in males and females of different age group.
This study included 100 subjects, in which 50 were males (Group A) and other 50 were females (Group B). After the formation of primary cast, all quantitative as well as qualitative characteristics of palatal rugae patterns were recorded. Mainly, two classifications were used in this study, Thomas and Kapali
Student -test was used, and "" value of <0.05 was considered statistically significant.
A statistically significant value was found in left-sided palatal rugae patterns depending upon the size, where we found that primary rugae were more in males. On comparing the angulation of palatal rugae patterns of left-sided rugae, a statistically significant value was found among the negative angulation which was higher in male subjects. Next, while comparing the angulation of palatal rugae of right side, we found a statistically significant value among zero (perpendicular rugae), which was more in male population. On comparing the unification of right-sided rugae patterns, we found that divergent rugae were more in male subjects.
Palatal rugae patterns act as individualistic, and are unique patterns, and are helpful in determining the human gender. Further, more studies are required on palatal rugae patterns used in forensics on large population scale.
腭皱襞检查是用于研究皱襞形态的术语。“皱襞”一词源于希腊语“seam”。此外，它与胎儿分化过程中两个生物结构部分的交叉、连接或缝合有关。本研究的目的是确定拉贾斯坦邦斯利甘加纳格尔人群中腭皱襞形态在长度、数量、形状、融合及方向上的性别差异。
目的是确定腭皱襞形态在长度、数量、形状、融合及方向上的性别差异；研究男性和女性腭皱襞划分的差异，并比较不同年龄组男性和女性的腭皱襞形态。
本研究纳入100名受试者，其中50名男性（A组），另外50名女性（B组）。制作初级模型后，记录腭皱襞形态的所有定量及定性特征。本研究主要采用两种分类方法，即托马斯分类法和卡帕利分类法。
采用学生t检验，P值<0.05被认为具有统计学意义。
根据大小，左侧腭皱襞形态存在统计学显著差异，我们发现男性的初级皱襞更多。比较左侧皱襞的腭皱襞形态角度时，在负角度中发现统计学显著差异，男性受试者的负角度更高。接下来，比较右侧腭皱襞的角度时，我们在零角度（垂直皱襞）中发现统计学显著差异，男性人群中更多。比较右侧皱襞形态的融合情况时，我们发现男性受试者中发散皱襞更多。
腭皱襞形态具有个体特异性，是独特的形态，有助于确定人类性别。此外，需要在大规模人群中对用于法医学的腭皱襞形态进行更多研究。
