Aim and objectives
The aim of this study is to find out the correlation between the cranial capacity and the sexual dimorphism.
Materials and Methods
38 dry human skulls originated from South India (20 males and 18 females) were obtained from the Department of Anatomy, Saveetha Dental College and Hospital, Chennai, Tamil Nadu, India, during the year of 2015. All the skulls used for this study are from the adult skulls which are approximately above 20 years.
The mean capacity for male skulls is calculated to be 1030.05 ± 35.65 CC (range 963 CC-1099 CC) and the mean capacity for female skulls is 850.24 ± 40.95 CC (range 757 CC-890 CC). The South India Sexual Dimorphism Index based on the cranial capacity of skull is 17.46%.
The mean cranial capacity among the South India adult dry skulls reveal that male have higher values of cranial capacity compared to female.
