Many studies on various populations have found differences in the tooth sizes between male and female subjects [12, 19, 20].
This may be attributed to racial differences in tooth sizes [ 25].
The differences in correlation values may be due to the genetic influence on the tooth sizes [ 25, 30].
There were statistically significant differences between predicted tooth sizes using equations from the present study and those predicted from the Tanaka and Johnston regression equations.
Humans have taken the smile to an even friendlier format, through the reduction in tooth size between archaic and modern hominids, most notably of the canines.
Jaw size and tooth size, for example, are not independent, and flexion of the base of the skull and being flat-faced are generally correlated.
Mesiodistal tooth size was smaller in poor Goslon yardstick scores.
Crowding was evaluated as tooth size-arch length discrepancy.
Maxillary mesiodistal tooth size was inversely associated with GOSLON Yardstick scores.
But in species in which larger males evolved, tooth size increased relatively little.
