Cephalometry is used for classification of sex and race of a person whose identity is not known. Skull is most important reliable bone for sex differentiation Cranial index also referred to as cephalic index is measured to categorize head shapes. The cephalic index is ratio of the maximum width divided by its maximum length multiplied by 100.
To verify if cephalic index can be used for sexual dimorphism.
MATERIALS AND METHOD
A group of 60 individuals were selected: 30 males and 30 females. After getting informed consent measurements were taken with the help of spreading calipers. All measurements were taken by a single observer to avoid error, three values were recorded and the average value were taken as the main value. SPSS software was used to analyze the data and related samples Wilcoxon signed rank test was done
Wilcoxon signed rank test was done, the p value was 0.192 (p>0.05). So, it is statistically not significant, hence sexual dimorphism cannot be determined using head circumference
Cephalic index is a very useful parameter for various anthropometric studies, from the present study we conclude that the Cephalic index is not reliable parameter for sexual dimorphism.
