Background: Tooth is the hardest and chemically (except mineral contents) the most stable structure in the body, which makes teeth as the first-rate material for genetic and forensic investigations. Sex determination of skeletal remains forms an important part of archaeological and medicolegal examinations. Hence, the aim of the present study was to analyse the morphometric and dimensional variation between male and female in north Indian population using maxillary arch parameters. Materials and Methods: Fifty male and fifty female patients of age group 18–35 years were randomly selected after taking detail history. All maxillary impressions were made with alginate and poured in type III dental stone. These casts were measured for maxillary inter-canine width, maxillary first inter-premolar width, anteroposterior palatal width and palatal depth using a digital vernier caliper and findings were correlated with sexual dimorphism. Results: The maxillary inter-canine width, maxillary first inter-premolar width, and palatal depth showed a significant difference with P < 0.05 between the means of two populations. Anteroposterior palatal width showed the comparatively less significant difference between two populations. Conclusion: Among north Indian population, maxillary inter-canine width, maxillary first inter-premolar width, and palatal depth can be used for sex assessment. The anteroposterior palatal width parameter is comparatively less significant in sex determination.
