This article presents a case of a two-rooted maxillary central incisor with previous endodontic therapy. One root canal was well filled and the other partially filled. A post was present in each root and the tooth had a crown. Surgery was performed and an amalgam retrograde filling was placed. A 6-month postoperative radiograph shows repair.
An injectable thermoplasticized gutta-percha system (Ultrafil) was used to fill 50 teeth which were monitored radiographically over a period of 24 months. An equal number of teeth were filled with the lateral condensation technique and used as controls. Radiographic evidence of success was determined at a 24-month recall. The results were subjected to a 2 x 2 analysis of variance (control versus experimental/before and after treatment. There was a significant amount of repair irrespective of obturation procedure (p greater than 0.0001). Thirteen teeth in the experimental group randomly filled with sealer showed that the sealer did not influence repair.
