Abstract

When inflammatory products are found in both periodontal and pulpal tissues simultaneously, a periodontal-endodontic combined lesion is established. The treatment of periodontal-endodontic combined lesions includes root canal therapy and periodontal regenerative procedure for resolution of both the apical and marginal inflammatory lesions. The present study reports the treatment of periodontal-endodontic combined lesions in the mandibular anterior area with root canal therapy, followed by guided tissue regeneration therapy. Teeth with severe bone destruction in each case could be preserved, without extraction, over a 3-year period. Therefore, it appears that treatment of periodontal-endodontic combined lesions in the mandibular anterior area using guided tissue regeneration technique after root canal therapy may provide clinical advantages.
