Objective: To evaluate the curative effect of intented replantation on refractory and chronic periapical periodontitis, and to analyse the relative factors. Methods: We reviewed 5 patients, who had 7 implicated teeth to be removed because of refractory and chronic periapical periodontitis. They underwent conversed filling of root canal and instantaneous replanted . All patients were more than 45 years old. 3 females had 5 implicated teeth, including 3 molars and 2 premolars, while 2 males had 1 molar and 1 premolar respectively. All teeth were removed under local anesthesia, wet curaged degenerative periapical tissue, conversed filling of root canal, instantaneous anatomy repaired tooth damnification, and replantated within 30 minutes. Results: 5 years later, each tooth represented normal gingival attachment, the average movement was Ⅰ°. The X-ray examination showed the periodontal membrance healed up. Conclusion: Replantation is widely used to treat traumatic dislocated teeth. The rate of the success is generally shown to be closely related with the hour between dislocation and replacement and the conserving manner of the teeth.
