ABSTRACT
Objective:
To study the relationship between Angle Class II division 2 malocclusion and congenital anomalies of dentition,Methods:
100 untreated patients (aged 12~42 years old) with Class II division 2 malocclusion were investigated by history,general examination,radiograph and tooth model. The data of congenital tooth anomalies were analysed.Results:
Congenital tooth anomaly was found in 50 of the patients. Upper lateral incisor enamel hypoplasia was found in 7 patients, small size of maxillary lateral incisor in 28, canine impaction in 4, missing of lower incisor in 9, transposition in 2 and anterior tooth Bolton ratio discrepancies in 30 of the patients.Conclusion:
Angle Class II division 2 malocclusion is closely related to congenital tooth anomalies. The main factors of anterior tooth Bolton discrepancies may be the small size of maxillary lateral incisor and absence of lower incisor.
