The size and shape of a tooth vary between individuals of different ethnic groups and genders because of the influence of different genetic factors. The information regarding the different anatomical factors using maxillary anterior teeth is very scanty. Thus to give more clarity, a study was planned to assess the correlation between head circumference and tooth-mesiodistal width among children of different ethnic origins.The study was carried out on 210 children aged 7 to 12 years in schools at Abha, Saudi Arabia.The mesiodistal (MD) width of the central incisor was measured using a digital vernier caliper. A Meter tape ruler was used to measure the Head/Cephalic dimensions. The data obtained were subjected to statistical analysis using IBM SPSS 20.0, and the results were analyzed. It was found that mean MD tooth width and head circumference were maximum in Saudi children, followed by South Asian and Arab/African, with an insignificant statistical difference (p-value > 0.05). Correlation between MD dimensions of maxillary central incisor with head circumference was statistically significant (p-value < 0.05) among Saudi and South Asian populations, whereas statistically insignificant (p-value > 0.05) difference between Saudi and Arab/African populations. It was concluded that there exist the ethnic differences between tooth-mesiodistal width and head circumference dimensions of children. A positive correlation between head circumference and mesiodistal width of the central incisor was determined.
