PURPOSE: While the objective of partial pulpotomy is to preserve the vitality and function of the pulp tissue, the preopera-tive pulp status is the main prognostic factor for its success. To date, however, there is little data on long-term success rates. Therefore, the aim of this prospective pilot study was to assess the long-term outcome of partial pulpotomy in per-manent teeth after carious pulp exposure without signs or symptoms of irreversible pulpitis, verified clinically, radio-graphically, and via MMP-9 levels.
MATERIALS AND METHODS: Patients in whom permanent teeth with extremely deep carious lesions were diagnosed as com-pletely asymptomatic (n = 8) or with signs of reversible pulpitis (n = 10) underwent non-selective caries removal followed by a blood test to assess the level of MMP-9. The teeth were thereafter partially pulpotomised, MTA-capped, and immedi-ately restored with composite resin. Follow-up examinations were performed by endodontically experienced examiners focusing on clinical and radiographic assessment.
RESULTS: One patient could not be contacted and was lost to follow-up. Overall, the follow-up period ranged from 2-8 years (mean = 4.4 years). The majority of teeth remained functional and without pathology; one tooth was classified as having failed because of a vertical root fracture. There was no statistically significant difference in the groups' success rate (p = 0.3). The estimated overall survival rate was 94.1% (95% CI: 0.84-1.00) after 4 years according to the Kaplan-Meier method.
CONCLUSION: Pulp vitality in permanent teeth can be preserved with high success rates by means of partial pulpotomy after carious pulp exposure in asymptomatic teeth or in teeth with reversible pulpitis.
