Transposition of teeth: A review of literature

Introduction: Tooth transposition is a rare developmental anomaly characterized by positional interchange of two teeth within the same quadrant. Its incidence compromises the esthetics and function to a significant degree. The current literature review is offered to highlight certain aspects of this anomaly to develop an understanding that might be helpful in management for restoration of esthetics and function of affected patients. Material and Methods: Several electronic databases were searched and hand searching was also done to recognize the consequent articles. A total of 46 studies were initially retrieved out of which 35 relevant studies were selected for the review. Results: Tooth transposition is a rare anomaly of permanent dentition and is not reported in primary dentition. Maxillary transpositions are more frequent and transpositions rarely occur in mandible. Maxillary canine is the most frequent tooth found to be transposed. Treatment depends on the location of affected teeth and age of the patient. Conclusions: Tooth transposition is a rare developmental dental anomaly that affects esthetics and function. A high-quality perceptive of this entity might be helpful to develop meaningful clinical management of the affected patient.
