Abstract:
OBJECTIVETo evaluate the pulp vitality, the periodontal condition and the success rate of autotransplanted teeth after orthodontic treatment.
METHODSA total of 20 permanent teeth (one of them had been treated by root canal therapy), 17 with completely developed roots and 3 with developing roots, were autotransplanted to the region of missing teeth in 16 admitted patients. Orthodontic treatment was carried out in all cases. Clinical and radiographic evaluation of the transplanted teeth was done.
RESULTSThe average time of postoperative orthodontic treatment was 1.9 months. In all, one autotransplanted tooth was lost because of periodontal disease during follow-up. Eight autotransplanted ones had positive electric pulp testing (EPT) response. Fifteen out of 20 autotransplanted teeth were surrounded by newly-formed periodontal space with normal size and lamina dura. The numbers of surviving and successful autotransplanted teeth were 19 and 15, respectively, after an average observation period of 24.5 months.
CONCLUSIONSOrthodontic treatment of autotransplanted teeth was acceptable and the pulp vitality of the teeth might be preserved.
