Mesiodistal Crown Dimensions of Permanent Teeth in Bangladeshi Population

Variation in tooth size is influenced by genetic and environmental factors 1 . Several studies have reported tooth size variation between and within different racial groups. Keene 2 reported racial differences in tooth sizes among the American Negroes and their Caucasian counterparts in caries-free naval recruits. Turner and Richardson also observed significant differences in mesiodistal tooth width in Kenyan and Irish populations. In another related study Bishara 3 compared the mesio-distal and bucco-lingual crown dimensions of the permanent teeth in three populations from Egypt, Mexico and the United States.
