Application of Partial Pulpotomy in the Treatment of Chronic Pulpitis Caused by Carious in Mature Permanent Teeth: 3 Year-Follow-Up

Purpose: To observe the clinical effect of partial pulpotomy with I Root Bp Plus in cariously exposed mature permanent teeth. Methods: twenty-three cariously exposed mature permanent teeth were choosen by preoperative clinical signs, pulp dynamic examination and imaging examination. After informed consent, rubber barrier was placed. The tooth decay and the inflamed pulp were removed by round bur. After 5% sodium hypochlorite covered the section until sufficient hemostasis was achieved, I Root Bp Plus was used to tightly cover the pulp with a thickness of about 2mm, resin was filled to repaired the shape of the tooth. The capping pulp was examined by X-ray immediately after operation. Clinical and imaging examinations were performed 12 months and 36 months after treatment. Results: After 3 year, the success rate of partial pulpotomy was 86.96%, which is similar as root cannal therapy. Conclusions: The partial pulptomy for caries exposed mature permanent teeth may be an alternative to root canal therapy, and is more consistent with the current concept of minimally invasive and preservation of vital pulp.
