Dental records, fingerprint, and DNA comparisons are probably the most common techniques used for a person's identification, allowing fast and secure identification processes. However, sometimes it is necessary to apply different and less known techniques such as lip prints. The potential of lip prints to determine sex has been well exhibited and documented. However, very few studies have been conducted using lip prints for population identification.
To determine the predominant lip print patterns in males and females in relation to Kerala and Manipuri population and also to compare the lip print patterns between these populations.
The sample comprised of 60 subjects, which included 30 each from Kerala and Manipuri. Lipstick was applied evenly, and the lip print was obtained by dabbing a strip of cellophane. The classification scheme proposed by Tsuchihashi was used to classify the lip print patterns and the data were statistically analyzed using the z-test for proportions.
Type 4 and Type 5 lip print patterns were predominant in males, whereas in females it was Type 1 and Type 1'. Type 1 pattern was most common in both the populations, with an incidence of 28.33%. Furthermore, Type 1 pattern was found to be more in Kerala females and Manipuri males when compared to their counterparts. Type 1 was most common in upper right, upper left, and lower left quadrants whereas in lower right quadrant, Type 1' and Type 4 were predominant in Kerala and Type 5 in Manipuri population.
Difference between the lip print patterns in two populations exists, although subtle. However, larger sample size is necessary to derive concrete conclusions.
牙科记录、指纹和DNA比对可能是用于个人身份识别的最常见技术，可实现快速且安全的身份识别过程。然而，有时有必要应用不同且鲜为人知的技术，如唇纹识别。唇纹识别在确定性别方面的潜力已得到充分展示和记录。然而，使用唇纹进行人群识别的研究却非常少。
确定喀拉拉邦和曼尼普尔邦人群中男性和女性的主要唇纹模式，并比较这两个人群之间的唇纹模式。
样本包括60名受试者，其中喀拉拉邦和曼尼普尔邦各30名。均匀涂抹口红，用一条玻璃纸轻拍获取唇纹。采用土桥提出的分类方案对唇纹模式进行分类，并使用比例z检验对数据进行统计分析。
4型和5型唇纹模式在男性中占主导地位，而在女性中则是1型和1'型。1型模式在两个人群中最为常见，发生率为28.33%。此外，与对方人群相比，喀拉拉邦女性和曼尼普尔邦男性中1型模式更多。1型在右上、左上和左下象限最为常见，而在右下象限，喀拉拉邦人群中1'型和4型占主导，曼尼普尔邦人群中5型占主导。
两个人群的唇纹模式存在差异，尽管很细微。然而，需要更大的样本量才能得出具体结论。
