Abstract
Forensic identification of sex determination using lip print analysis in North Bihar, India is of interest. The analysis of lip prints consisted of data collection points during baseline, 6 months and 12 months. However, no significant time-related alterations (p > 0.05) were found indicating their enduring nature. Lip print collection through lipstick and digital photography was successful similar to latent method that proved successful except in male participants who used latent documentation at baseline.
