Objective:To determine the sex and stature of an individual using tooth crown dimensions (Mesiodistal & Buccolingual) and intercanine distance in ethnics of South Indian Population, by using Pearson correlation and linear regression. Methods:Dental casts of 70 male and 70 female individuals between 17-30years of age made with strict standardization were subjected to analysis of intercanine distance, mesiodistal & buccolingual dimensions of upper and lower teeth. Individualsupto 2 generations included were those whose ethnic origin was from South India with their history recorded and height were measured in centimetres using standard anthropometer. Teeth dimensions were measured upto two decimal places with a digital calliper. Intra- and inter-observer reliability was done. Results:The statistical analysis of the data obtained was done using SPSS for Windows [Version 17]. The descriptive statistics such as mean and standard deviation were calculated. Correlation between tooth measurements and height and gender was done using Pearson’s correlation and linear regression method was applied to arrive at a formula to predict stature and gender using inter-canine distance. Conclusion: There is definite usefulness of dentition in gender and stature prediction and this data could be used in forensic investigations.
