Aim To identify periapical changes in nonsurgically retreated root filled teeth 20–27 years after root canal treatment. Methodology From an original material of 429 roots, retreated by undergraduate students in a teaching clinic, 112 roots in 70 individuals could be evaluated radiographically 20–27 years after treatment. The same roots had been studied 10–17 years earlier. The periapical Preoperative radiograph (a) shows canine with periapical lesion; postoperative radiograph (b) shows same tooth after root canal treatment. Persistent radiolucency noted at 5-year follow-up (c) was removed surgically (d).

Study design: Fifty-four root-filled teeth with persisting periapical lesions were selected for re-treatment. After removal of the root filling, canals were sampled by means of advanced microbiologic techniques. The teeth were then re-treated and followed for up to 5 years.
