Correlation between head circumference and mesio-distal width of the maxillary central incisor: a cross sectional study among three different population groups

The size and shape of a tooth vary between individuals different ethnic groups genders because the influence genetic factors. information regarding anatomical factors using maxillary anterior teeth is very scanty. Thus to give more clarity, study was planned assess correlation head circumference tooth-mesiodistal width among children origins.The carried out on 210 aged 7 12 years in schools at Abha, Saudi Arabia.The mesiodistal (MD) central incisor measured digital vernier caliper. A Meter tape ruler used measure Head/Cephalic dimensions. data obtained were subjected statistical analysis IBM SPSS 20.0, results analyzed.

Correlation dimensions statistically significant < 0.05) populations, whereas Arab/African populations. concluded there exist differences children. positive determined.
