Delayed partial pulpotomy in a midroot and complicated crown-root-fractured permanent incisor with hyperplastic pulpitis: a case report.

INTRODUCTION: The occurrence of multiple injuries of the same tooth is extremely rare. This case report describes the treatment in a midroot and complicated crown-root-fractured permanent incisor that remained untreated for 4 years after the accident.

METHODS: The tooth was treated by delayed partial pulpotomy using calcium hydroxide.

RESULTS: At the 3-year follow-up after treatment, the tooth was still vital and functional without any clinical and radiographic signs and symptoms.

CONCLUSIONS: A young permanent tooth with hyperplastic pulpitis caused by trauma has a great inherent defensive capacity to heal after delayed partial pulpotomy despite adverse conditions.
