Abstract:

In this 17-year-old case, considering the patient was young and the principle of preserving teeth and pulp was followed, the vital pulpotomy was first used to preserve part of the vital pulp. However, the internal root resorption image was found in the first follow-up three months after the operation, so the treatment plan was changed to root canal therapy. Through this case study, the reasons for the failure of pulp preservation and internal root resorption after permanent pulpotomy were discussed, in order to provide a new idea for the treatment of mature permanent teeth with carious pulp exposure in the future.

Key words: vital pulpotomy, internal root resorption, reversible pulpitis
