The aim of the present study was to examine whether a putative relationship exists between the Class II division 2 craniofacial type and congenital anomalies of the dentition, such as missing teeth, peg-shaped laterals, transpositions, supernumerary teeth and canine impactions. Two hundred and sixty-seven untreated patients with Class II division 2 malocclusion were examined. 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 incisors, 7.5 per cent peg-shaped upper laterals, while impacted canines were present in 33.5 per cent of the subjects. Tranpositions were present in 1.1 per cent of the patients and in all cases the canine was involved. No patient exhibited a supernumerary tooth.

Comparing the results of the present study with existing data on the percentage of congenital tooth anomalies in the general population, it can be concluded that Class II division 2 malocclusions are closely associated with congenital tooth anomalies.
