Transgenders are highly disadvantaged people, deprived of adequate opportunities of earning a respectable living. The forensic literature has emphasized on two genders, male and female, the existence of a third gender (Transgenders) is almost negligible in the literature, and this makes it compulsive to determine their identity through forensic approaches at the time of disasters. Previous studies have demonstrated that no two palatal rugae pattern are alike in their configuration and this unique feature has led us to undertake a study to establish individual identities using palatal rugae pattern.
The purpose of this study was to compare the palatal rugae pattern among male, female, and transgender population of the Bhopal city.
This study was cross sectional in nature and conducted on a convenience sample of 148 subjects selected from Bhopal city, Madhya Pradesh. The study involved 49 males, 51 females, and 48 eunuchs in the age range of 17 to 35 years.
Maxillary impression using alginate impression material was made and the cast was prepared using die stone on palatal area and dental stone as a base. The palatal rugae pattern was assessed on the basis of number, length, shape, direction, and unification.
One way ANOVA was used for comparing the mean values between different genders. The multiple pairwise comparisons were done with the Bonferroni post hoc correction. The statistical significance was fixed at 0.05.
The statistically significant difference with regard to some parameters like number of rugae, fragmentary rugae, wavy rugae, curve rugae, forwardly directed, and backwardly directed rugae between transgender and other gender groups were present.
The difference in the parameters of the palatal rugae pattern among the transgender population and the other gender group is attributed to be the genetic makeup and sexual dimorphism.
跨性别者是弱势群体，被剥夺了体面谋生的充足机会。法医学文献一直强调两种性别，即男性和女性，第三种性别（跨性别者）在文献中的存在几乎可以忽略不计，这使得在灾难发生时通过法医方法确定他们的身份成为必要。先前的研究表明，没有两个腭皱襞图案的形态是相同的，这一独特特征促使我们开展一项研究，利用腭皱襞图案来确定个体身份。
本研究的目的是比较博帕尔市男性、女性和跨性别者群体的腭皱襞图案。
本研究为横断面研究，对从中央邦博帕尔市选取的148名受试者的便利样本进行研究。研究涉及年龄在17至35岁之间的49名男性、51名女性和48名阉人。
使用藻酸盐印模材料制取上颌印模，并在腭部区域用石膏制作模型，以牙科石膏为基底。根据数量、长度、形状、方向和融合情况评估腭皱襞图案。
采用单因素方差分析比较不同性别之间的均值。使用Bonferroni事后检验进行多重两两比较。统计学显著性设定为0.05。
跨性别者与其他性别群体之间在一些参数上存在统计学显著差异，如皱襞数量、碎断皱襞、波浪状皱襞、曲线状皱襞、向前指向和向后指向的皱襞。
跨性别者群体与其他性别群体之间腭皱襞图案参数的差异归因于基因构成和性二态性。
