Sexual dimorphism refers to the differences in size, stature, and appearance between male and female. In many species, teeth exhibit sexual dimorphism. Varying degree of sexual dimorphism in human dentition has been shown in many studies. Hence, tooth size standards based on odontometric investigations can be used in sex determination. In many studies on contemporary human population, it has been shown that tooth crowns are larger in males than in females in possibly due to a longer period of amelogenesis for both deciduous as well as permanent teeth in males. 200 subjects, 100 males and 100 females in the age group of 18 – 30 years were selected for this study. The present study was carried out at Ratna dental hospital, Bikaner, India. The mean age for males was 26.14 (±3.08) years and 22.35 (±3.55) years for females. Mean age of males was found to be significantly higher as compared to that of females (p=0.000001). Inter canine distance was found to be significantly higher as compared to that of females (p=0.000001). In present study sexual dimorphism was observed 13.74%.
