Aim:The aim of this study was to analyze the morphological study of palatal rugae pattern in a central Indian population and to determine sex differentiation.Objectives:To investigate the distinctive rugae patterns of the study population and determine the contribution of rugae patterns in gender identification.Material and Methods:The present cross-sectional study was conducted among a Central Indian population with a sample size of 500 participants. The study involved 250 males and 250 females who were randomly selected from the outpatient department of Oral Medicine Diagnosis and Radiology, Hitkarini Dental College and Hospital, Jabalpur, Madhya Pradesh. After collection of impression, casts were made and analyzed to evaluate the palatal rugae pattern in a central Indian population by using Thomas and Kotze classification (1983) for number, shape, direction, and unification of palatal rugae pattern. The statistical analysis was carried out using Mann–Whitney test and Chi-square (χ2) tests for categorical variables.Result:Males showed more number of rugae than females [P = 0.00 (≤0.001)]. Males had more number of wavy rugae pattern whereas females showed more number of straight rugae patterns [P = 0.00 (≤0.001)]. Males showed more backwardly directed rugae whereas females showed more forwardly directed rugae [P = 0.00 (≤0.001)]. The unification did not show any significant difference.Conclusion:This study showed that there was a significant relationship between palatoscopy, human identification, and sex determination. Thus, palatoscopy can be considered as a cost effective, easy, unique, and stable method for human identification.

A sample of 50 subjects (25 males and 25 females) aged between 20 and 40 years were included in the study. Two sequential techniques were followed. Dental casts and pictures were analyzed by 3 blind observers by comparison of dental traits and then confirmed by superimposition using Adobe Photoshop CC. Positive identification was achieved by application of two techniques. ICC Multiple Raters and ICC Two Raters were applied to analyze the stratum of agreement between the observers.

“…The forensic aspect of this analysis comes into play when it is applied to identify teeth marks left on food or in criminal cases when the victim bites the assailant in self defense or when such marks are seen on the victim as left by the assailant in cases like sexual assault. [ 7 ]…”

Objectives:This study attempts to highlight the usefulness of applying Berry's Index as an adjuvant to support and aid in bite analysis.Materials and Methods:This study was conducted among 100 students between the ages of 18–30 from Mar Baselios Dental Collage, Kothamangalam. Out of the 100 subjects, there were 50 males and 50 females. The data obtained was tabulated and analyzed using Statistical Package for Social Sciences, Version 16 (SPSS).Results:The mean value of the width of the upper central incisor for male and female was 0.7602 cm and 0.7765 cm respectively. The mean value of the bizygomatic width for male and female was 12.54 cm and 12.42 cm respectively. The correlation between the upper central incisor width and the bizygomatic width was inferred to have a good positive correlation with a value 0f 0.613. Pearson correlation coefficient with greater correlation between the upper central incisor width and the bizygomatic width in female patient (r = 0.678) compared with male patient (r = 0. 525).Conclusion:Berry's Index can be a useful adjuvant to bite analysis by providing a means of determining the facial proportions of an individual from the width of the central incisors.
