[Tooth transposition: results of an enquiry among practitioners].
A questionnaire was sent to orthodontists in order to analyse transpositions of teeth and their treatment. The results of this study confirm that most transpositions are maxillary canine/premolar transpositions. These transpositions were found to be often associated with other dental abnormalities (such as agenesis and peg-shaped laterals). Considerable evidences supports they are genetic in origin, but, in accordance with the demands of evidence-based science, further study is needed to prove it. The results suggest that most practitioners try to correct transposition despite the many difficulties involved. Early diagnosis did not reduced treatment time nor diminish difficulties.
