Papillary reconstruction and guided tissue regeneration for combined periodontal–endodontic lesions caused by palatogingival groove and additional root: a case report

Abstract

We described a combined periodontal–endodontic lesion, which was caused by a palatogingival groove and an additional root. An interdisciplinary approach involving endodontic therapy, mineral trioxide aggregate ( MTA ) filling, root resection, guided tissue regeneration, and papillary reconstruction was used for the case. The tooth presents morphologically and functionally normal except tooth discoloration caused by MTA .
