[Canine tooth transposition study on a group of patients orthodontically treated]

The dental transposition is an eruption anomaly, which occurs in this process towards the final stage and that represents the switching of 2 teeth that are next to each other. The tooth that most often is involved in transposition is the canine tooth, most frequently the upper one, which switches places either with the first premolar either with the lateral incisor. Under a clinical aspect, the transposition can be total (complete) or partial (incomplete), the latter reported both for crowns and roots. The clinical manifestation of the anomaly imposes the characteristic signs and the individualized therapeutical attitude. The dental transposition must be differentiated within the eruption anomalies from the transmigration, which defines the displacement of a tooth inside the bone beyond the median line, this tooth usually being the lower canine. Our study, which was conducted on a small group of 34 patients, shows the results of the analysis of the anomaly versus the gender, the type of the transposition, the affected maxillary etc.
