skulls: MT= 7.13 mm in superior middle cell; MT= 7.14 mm in superior posterior cell; MT= 5.02 to 5.50 mm in middle anterior, middle and posterior cells with no statistically significant difference between MT values; and MT= 5.51 mm in inferior posterior cell (Table II).
The 69.44% of patients were mesocephalic
, 22.22% and 11.11% brachycephalic dolichocephalic.
The angles to be analyzed were: the nasolabial angle, formed by the nose columnela and the nasolabial projection; the interincisal angle conformed by the upper and lower incisors; the mentolabial groove depth, that gave the length of depth between the lower lip and the chin; and the mandibular plane angle, which divide the sample, due to its degree of divergence with Frankfort's plane, into brachycephalic ([greater than or equal to] 25[degrees]), mesocephalic
([greater than or equal to] 30[degrees]) and dolichocephalic ([greater than or equal to] 35[degrees]) (Fig.
females) in western Kentucky were reported for combined age and sex classes in Lindeman (2000b), but further breakdown by class is given in other sources (Lindeman, 1997, 2013), allowing a UPGMA diagram to be constructed for comparison to Figure 1.
Also, in tropical zones head form is longer (dolichocephalic), but in temperate zones the head form is more round (mesocephalic
or brachycephalic) (Bharati et al., 2001).
Conclusion: In Vindhya region of Madhya Pradesh, there is predominance of mesocephalic
In the present study when taken irrespective of race, the dominant head form is mesocephalic
, but the endogamous group differentiation is evident and this shows that the shape of head depends on hereditary factors.
The hemi-mandibles studied were from dolichocephalic (n= 35), brachycephalic (n= 35) and mesocephalic
(n= 35) heads, all free from macroscopic abnormalities and having, at least, a steady, well-formed, not-decayed and orthodontically well-positioned second molar.
This finding is similar to another study was done on Fars males in North of Iran, reported that 52% of individuals were hyperbrachycephalic, 25% brachycephalic (Golalipour, 2006a), and another study in Tehran-Iran, reported that 36.6% of the individuals were brachycephalic, 29.9 % hyperbrachycephalic that it differ from the study in India (Bhatia et al., 1955), which reported the dominant type dolicocephalic (58.5%), del Sol study in Chile and other study with mesocephalic
(Marquer & Chamela, 1961).
People with cephalic index between 76 and 80.9 belong to mesocephalic
type of the head.
On the basis of this index, skulls were classified as hyperdolichocephalic, dolichocephalic, mesocephalic
, brachycephalic, and hyperbrachycephalic.
The dolicocephalic type of head shape was dominant in the Kanuri males (66.7%) and females (43.3%), while the mesocephalic
type was dominant in the Babur/Bura males (50%) and females (63.3%).The rare types of head shape observed in this study were the brachycephalic and hyperbracycephalic type being completely absent in the males of both ethnic groups (Table II).
