Comparative Study of Incidence of Parietal Foramina in North and South Indian Human Crania

1189, non-pathological dried crania from north and south Indian were studied. The incidence of parietal foramen was highest in south Indian male(113.9%) and female(112.2%) crania. While incidence of parietal foramen in North India (104%) and female(90.46%) crania. Moreover measurement was taken from parietal foramen to bregma by measuring tape. The mean value of south Indian male crania was 91.42cms ±0.23(SD = 2.02) and female mean value was 86.50cm ±0.27 (SD = 1.68) with highly significant P value (P<0.050 similarly mean value of north Indaian male crania was 89.85cms ±0.6 (SD=1.88) and mean value of female crania was 87.12 cms ±0.23 (SD=1.90) with highly significant P value (P < 0.01). the logistic regress ion equation for classification of sexual dimorphism of north Indian crania was 70.8% and south Indian crania was 66.5%. while, in the regional classification of male crania of North and South India was 69.9% and female crania of north and south India was 66.4%

As there is no parameter for calvaria to find out sexual dimorphism and regional classification, hence this study will certainly help the medico legal experts, anatomists and anthropologists.
