The data were analyzed using the chi-square test and P? 0.05 was considered significant. The results showed that Type II and Type I lip Print patterns were the predominant patterns for both Males and Females. There was a significant difference in lip prints of both males and females. There was a higher frequency in the number of non-tongue rollers than that of those who could roll their tongue, with no significance to sex.
