Lip prints are very useful in forensic investigation and personal identification. Like finger prints, even lip prints can be instrumental in identifying a person positively.
Indians are closer to Mongoloids than to Caucasoids or Negroids as indicated by the phylogenetic tree. Most of the studies on lip prints are done in their own population. We have compared lip prints of Manipuris with other Indians (Aryans and Dravidians) who are both close to Mongoloid race and are genetically similar.
A total of 100 students 50 males and 50 females were selected of whom 30 males and 30 females were of Aryan and Dravidian features and 20 males and 20 females showed the Mongol features. Study materials used were Red colored lipstick, Lip brush, Cellophane tape, White chart paper and Magnifying lens. The lip prints were analyzed by dividing them into eight compartments.
Analysis of lip prints showed that the most common and the least common pattern in both males and females (Aryans-Dravidians and Mongols) were the same, but the compartment wise distribution of the lip patterns was different.
In the present study, it is established that there is no similarity of lip prints from one individual to another individual and between males and females. Regarding the comparison with Mongols, more studies with a larger sample size is necessary.
唇纹在法医调查和个人识别中非常有用。与指纹一样，唇纹也有助于准确识别一个人。
系统发育树表明，印度人比高加索人或黑人更接近蒙古人种。大多数关于唇纹的研究是在其本国人群中进行的。我们比较了曼尼普尔人与其他印度人（雅利安人和达罗毗荼人）的唇纹，这些印度人都接近蒙古人种且在基因上相似。
共选取100名学生，其中50名男性和50名女性，其中30名男性和30名女性具有雅利安和达罗毗荼人的特征，20名男性和20名女性具有蒙古人种的特征。使用的研究材料有红色口红、唇刷、玻璃纸胶带、白色绘图纸和放大镜。唇纹被划分为八个区域进行分析。
唇纹分析表明，男性和女性（雅利安 - 达罗毗荼人和蒙古人）中最常见和最不常见的模式相同，但唇纹模式在区域上的分布不同。
在本研究中，确定了从一个个体到另一个个体以及男性和女性之间的唇纹不存在相似性。关于与蒙古人种的比较，需要进行更多样本量更大的研究。
