Abstract

Identification of sex is very important in forensic science. The hardest structure in the body will be teeth, and considering very important for sex identification. Sexual dimorphism of teeth is considered unique and research is going on to establish the parameters for sexual dimorphism in teeth in a forensic point of view. There are numerous studies are going on non-metric analysis for determination of sex. This study attempts to establish sexual dimorphism using teeth in Guntur district population using univariate and multivariateanalysis.

The sample consisted of 100 individuals (50 males and 50 females) within age group of 20–30 years. The majority of the individuals were in the 23–27 years age group. Both maxillary and mandibular impression was taken cast was poured using dental stone. Buccolingual and mesiodistal dimensions were measured using digital vernier caliper. Univariate sexual dimorphism using descriptive stastical analysis was done using Student t-test.

Age range from 20–30 years and mean age group of 22.2 ± 1.2 years. The buccolingual (BL) and Mesiodistal (MD) measurements in both maxillary and Mandibular teeth, larger teeth were observed in males when compared with females.

The MDand BL crown measurements were significantly greater in males when compared with that of females. Interestingly the MDdimension of maxillary left lateral incisor was greater in females when compared with males in case of Guntur population.
