Intentional Partial Pulpotomy for Treatment of Immature Permanent Maxillary Incisor with Talon Cusp

We report the successful morphological correction of a maxillary lateral incisor with a talon cusp and the preservation of vital pulp by employing an intentional partial pulpotomy. A talon cusp is a comparatively rare morphological tooth anomaly that may cause multiple clinical problems. An 11-year-old girl was referred to our department for morphological correction of a maxillary lateral incisor with a talon cusp prior to orthodontic treatment. Following a detailed CT examination of the interior morphology, the abnormal cusp was resected and an intentional partial pulpotomy performed. Five years postoperatively, the tooth showed no abnormalities. These results indicate that an intentional partial pulpotomy following a detailed CT examination is effective in correcting complicated morphological anomalies such as a talon cusp containing extended dental pulp.
