Postoperative pain was significantly lower in patients undergoing root canal instrumentation with the Wave-One file compared with the ProTaper Universal and hand files.

Eighteen canine mandibular premolars were divided into 3 groups. In group 1, implants were inserted in periapical lesions. In group 2, implants were inserted when lesions were radiographically healed. In group 3 (control), implants were inserted immediately after extraction. There was no significant difference in average bone implant contact between the 3 groups. Considering the limitations of this study, immediate placement of dental implants in tooth sockets with periapical lesions should be proposed only under special circumstances.
