          ABSTRACT

          Objective:

          The present article aims at reporting the clinical case of a patient who suffered trauma at two years of age, causing almost complete apical displacement of the deciduous maxillary left central incisor and of the permanent incisor.

          Methods:

          Ectopia secondary to intrusion was minimized by surgical removal of the ectopic tooth, and the left permanent canine was submitted to orthodontic traction to replace the extracted tooth.

          Results:

          The treatment period lasted 36 months, resulting in correct occlusion and a good aesthetic outcome.

          Conclusions:

          Dental transposition carried out by means of orthopedic traction is a good alternative in cases of a very unfavorable ectopic tooth position.

          RESUMO

          Objetivo:

          o presente relato de caso descreve uma paciente que sofreu trauma aos dois anos de idade, causando deslocamento apical quase completo do incisivo central esquerdo decíduo e do incisivo permanente.

          Métodos:

          a ectopia resultante da intrusão foi minimizada pela remoção cirúrgica do dente ectópico, e o canino permanente esquerdo foi tracionado ortodonticamente para substituir o dente extraído.

          Resultados:

          o período de tratamento durou 36 meses, obtendo-se uma oclusão correta e um bom resultado estético.

          Conclusões:

          a transposição dentária realizada através da tração ortopédica é uma boa alternativa em casos de dentes ectópicos em posições muito desfavoráveis.

            A long-term study of 370 autotransplanted premolars. Part II. Tooth survival and pulp healing subsequent to transplantation.

            The purpose of the present investigation was to determine the long-term prognosis of autotransplanted premolars with respect to tooth survival and pulpal healing. The material consisted of 195 patients aged 7 to 35 years, with a total of 370 autotransplanted premolars with observation period ranged from 1 to 13 years. Teeth transplanted with incomplete and complete root formation showed 95 per cent and 98 per cent long-term survival respectively: Pulp healing as evaluated by sensibility testing and radiographic signs of partial pulp canal obliteration was usually verified 6 months after transplantation. The frequency of pulpal healing (versus pulp necrosis), appeared to be closely related to stage of root development at time of transplantation. Teeth transplanted with incomplete and complete root formation showed 96 per cent and 15 per cent pulp healing respectively. Another and associated factor which could equally well predict pulpal healing was the diameter of the apical foramen of the graft. Finally, in teeth with completed root formation, the use of bursa with internal cooling and no extra-alveolar storage prior to transplantation seemed to increase the chance for pulpal healing. The present study indicates, that the size of the apical foramen and possibly the avoidance of bacterial contamination during the surgical procedure are explanatory factors for pulpal healing.
