Background:The “gender determination” which is an important human identification procedure not only helps in establishing the biological profile from skeletal and dental remains but also in facial reconstruction of unidentified victims.Aim:The aim of this study is to analyze predominant types of lip prints (cheiloscopy), accuracy of mandibular canine index (MCI) (odontometric), and facial index in the study population and to identify whether any correlation among the above parameters could help forensic dentistry in solving crimes.Materials and Methods:A pilot study was conducted in 100 individuals, 50 males and 50 females aged between 20 and 25 years. For each individual, the lip prints, MCI, and facial index measurements were recorded on the same day analyzed by two observers. All the analysis was done using SPSS version 14 assessed using t-test and Chi-square test.Results:Type II pattern of lip prints is observed as common pattern among male and female. There is no significant difference in Odontometric analysis. The mean value of facial index analysis in both genders shows highly significant.Conclusion:A large-scale study is required in order to validate our results to arrive at definitive results and value.

Aim:To assess the estimation of chronological age based on the stages of third molar development following the eight stages (A–H) method of Demirjian et al. in Chennai population of South India.Materials and Methods:A sample consisting of 848 individuals (471 males and 377 females) aged between 14 and 30 years was randomly selected for the clinical evaluation and 323 orthopantomograms with clinically missing third molars were taken for radiological evaluation using Demirjian's method from a Chennai population of known chronological age and sex. Statistical analysis was performed using Pearson's Chi-square test and mean values were compared between the study groups using t-test or analysis of variance (ANOVA) followed by Tukey's highly significant difference (HSD). In the present study, P < 0.05 was considered as the level of significance.Results:The results showed that the mean age of having clinically completely erupted maxillary third molars was 22.41 years in male subjects and 23.81 years in female subjects and that of mandibular third molars was 21.49 years in male subjects and 23.34 years in female subjects. Mandibular third molars were clinically missing more often in females than in males. Eruption of mandibular third molars was generally ahead of the emergence of maxillary third molars into the oral cavity. Third molar development between male and female subjects showed statistically significant differences at calcification stage F and stage G in maxillary third molars and stage F in mandibular third molars (P < 0.05).Conclusion:There are differences indicating that maxillary and mandibular third molar eruption reached Demirjian's formation stages earlier in males than in females. It is suggested that in future studies, to increase the accuracy of age determination, indications of sexual maturity and ossification should also be evaluated in addition to third molar mineralization.
