Forty-eight dental casts (37 males, 11 females) of Uva Bintenna Veddas were the population. Mesiodistal (MD) and buccolingual (BL) diameters were measured and analyzed for sexual dimorphism and size variation. In males, MD of maxillary canines and mandibular first molars were significantly greater at p p p p p 1, P1, and M1 showed least variability in both arches and in both sexes. In males, both MD and BL showed high variability in maxillary lateral incisors and mandibular second premolars.
