ABSTRACT:
Cranial capacity, which is in close correlation with brain volume, reflects racial characteristics and thus has been thought to be one of the commonest items in physical anthropological studies[1]. A few studies have been made on living subjects. This information is useful in correlating cranial capacity with other parameters like age, sex and BMI and in studies of primate phylogeny. Medically, an analysis of cranial capacity exposes another aspect of growth and development and permits critical evaluation of unusually large, small or misshapen [2,3]. An attempt has been made in the present study to estimate the cranial capacity of living subjects using the linear dimensions of the heads in 16-20 years old healthy Tamilnadu population. The purpose of the study was to investigate the relation between the cranial capacity and age, body weight, body height, body mass index (BMI) in living subject.The research was planned to assess the correlation of cranial capacity with age, gender, weight, height and body mass index of Tamilnadu population which includes Saveetha Dental College students.Brain volume grows rapidly from birth to childhood before fifth year. Between the ages 16-20, brain volume reaches its maximum amount and will not grow after that through life [4,5].
