The Class II division 2 craniofacial type is associated with numerous congenital tooth anomalies

The aim of the present study was to examine whether a putative relationship exists between the Class II division 2 craniofacial type and congenital an omalies of the dentition, such as missing teeth, peg-shaped laterals, trans positions, supernumerary teeth and canine impactions. Two hundred and sixty -seven untreated patients with class II division 2 malocclusion were examin ed. The results show that 56.6 per cent of the patients exhibited some form of congenital tooth anomaly 13.9 per cent agenesis of the upper lateral in cisors, 7.5 per cent peg-shaped upper laterals, while impacted canines were present in 33.5 per cent of the subjects. Transpositions were present in 1 .1 per cent of the patients and in all cases the canine was involved. Na pa tient exhibited a supernumerary tooth. Comparing the results of the present study with existing data on the percen tage of congenital tooth anomalies in the general population, it can be con cluded that Class II division 2 malocclusions are closely associated with c ongenital tooth anomalies.
