Abstract

The term 'triple tooth' is used to describe a rare dental abnormality in which three teeth appear to be joined. The literature contains many reports of joined primary teeth; most cases have involved, however, the joining of two teeth, and only rarely three teeth. Triple tooth has clinical problems such as dental caries, esthetic problems, malocclusions, and periodontal problems. Therefore, it may require multi-disciplinary approach. The present study describes rare case of triple tooth between maxillary primary central and lateral incisors and a supernumerary tooth. An one-year, eleven-month old girl was seen for evaluation of swelling in the labial gingiva above a right maxillary triple tooth. She experienced traumatic dental injury in that area three weeks ago. Intraoral examination revealed an abscess and fistula in the region of the triple tooth. A radiographic examination showed that right lateral incisor was missing. Endodontic treatment and composite resin restoration was performed on the triple tooth. After follow-ups of 7 months period, there were no marked complications.
