Bottom Line: According to classification by Tsuchihashi, the lip prints were analysed.It was found that Type I was the most prevalent cheiloscopic pattern.Although cheiloscopy holds promise as a supplementary tool along with other modes to recognize the sex of an individual, there is need for further studies using standardized methods to evaluate the same in larger population sizes.

ABSTRACT

Background: Cheiloscopy or the study of lip prints is an important tool in forensic dentistry which is gaining popularity in current times. Not only has it proven effective in identification of individuals, but its role in sex determination has also been investigated. There are six different types of cheiloscopic/lip print patterns according to Tsuchihashi.

Aims: The present study was conducted to find the prevalence of cheiloscopic/lip print pattern in 755 individuals and also to assess their efficacy in sex determination.

Materials and methods: According to classification by Tsuchihashi, the lip prints were analysed. Sex determination using lip print was done by method given by Vahanwala et al.

Results: It was found that Type I was the most prevalent cheiloscopic pattern. Based on the method of sex determination using lip prints by Vahanwala et al., the percentage of individuals correctly identified was less.

Conclusion: Although cheiloscopy holds promise as a supplementary tool along with other modes to recognize the sex of an individual, there is need for further studies using standardized methods to evaluate the same in larger population sizes.

Figure 11: Comparison of actual and predicted sex based on cheiloscopic/lip print patterns

Mentions: One hundred and thirty-one males out of 375 were correctly identified and 267 females out of 380 females were correctly identified. The accuracy of lip print patterns in sex determination was 17.4% in males and 35.4% in females. A low kappa value of 0.05 was obtained signifying that lip prints were not effective in sex determination [Table 4, Figure 11]. The Chi-square test applied to test significant difference between males and females for different types of lip patterns did not show a significant difference [Table 5].
