Tooth size symmetry--a comparative analysis of tooth sizes among secondary school children.

A study was carried out to determine the mesio-distal crown dimensions of permanent teeth, and to find out if there were any symmetry of the tooth sizes in a population of Nigerian children. The sample consisted of 250 secondary school children (125 males and 125 females) randomly selected from 3 secondary schools within Ibadan metropolis. Their age ranged from 12-15 years the mean age was 12 +/- 0.5 years. The results showed that there were no significant differences (p > 0.05) between the right and left sides of the dental arch with the exception of the maxillary second premolars and the female mandibular canines.
