Themorphological dimensions of head and face were measured with a scaled cephalometer and a sliding caliper Using the classical cephalometry .ephalic and prosopic indices were determined. The Chi-square and t-test were used to compare data.<br> <strong>Results</strong>: Means and standard deviation of cephalic indices were 78.4&plusmn;4.15 and 81.94&plusmn;4.99 and prosopic indices were 83.22&plusmn;4.02 and 84.86&plusmn;5.15 in Sistani and Baluchi subjects respectively. Based on the cephalic index, the dominant and rare head types in Sistani group was mesocephalic (4 1.3%) and hyperbrachycephalic (6%), and in BIachui group was brachicephalic (42%) and dolichochephalic(5.5%) respectively. Furthermore, according to the prosopic index, the dominant and rare face type among sistanis were euryprosopic type (50.8%) and hyperleptoprosopic (0.5%) and in Baluchi group were euryprosopic (37%) and hyperleptoprosopic (2.5%) respectively.<br> <strong>Conclusion</strong>: This research showed that differences in terms of head and face type indices between these two groups were statistically significant. Based on this cross-sectional study, it seems that there is differences between the aforementioned groups.
