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 < 0.01 and maxillary first molars and mandibular second molars
at p < 0.05. Crown area was
significantly greater at p < 0.01
for maxillary and mandibular first molars. Crown module was significantly
greater at p < 0.01 for mandibular
first molars and at p < 0.05 for
maxillary first premolars, first molars and mandibular second molars. Maxillary
canines, maxillary first molars and mandibular canines were the most sex ually
dimorphic. First tooth of each tooth class I1, 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.
