Is Intentional Replantation Appropriate for Treatment of Extensive Endodontic-periodontal Lesions Related to Palatogingival Groove?

This report describes the cases of two patients with a maxillary lateral incisor with palatogingival groove and extensive endodontic-periodontal lesions. Although it is reported that acceptable periodontal status is of great importance in case selection in intentional replantation, it is suggested in this report that intentional replantation could be chosen instead of immediate extraction if extensive endodontic-periodontal lesions exist in a tooth with palatogingival groove. The gingival margin position and gingival papilla were well preserved and the bone defect was almost completely repaired. This was beneficial to the aesthetic prosthodontic treatment and implantation, although external root resorption was observed.
