Objectives: This systematic review aimed to evaluate the clinical and radiographic outcomes of coronal and partial pulpotomies in mature permanent molars with cariously exposed vital pulp. Method and materials: The protocol of the current review was registered in the PROSPERO database (CRD 42020190785). Articles published between January 1980 and June 2020 were searched in eight different online databases and six textbooks according to PRISMA guidelines. Eleven studies were included in the analysis of 1-year success rates, whereas five studies were included in the analyses of 2-year and > 2-year success rates for coronal pulpotomy. Two studies were included in the analyses of the 1-year and 2-year success rates for partial pulpotomy. The clinical and radiographic success rates were estimated using the DerSimonian-Laird random effect method. The risks of bias were evaluated using Cochrane RoB 2, ROBINS-I, and Newcastle-Ottawa scale assessment tools. Evidence levels were determined using the Oxford Centre for Evidence-Based Medicine (OCEBM) recommendation tool. The success rates using different pulp capping medicaments and restorative materials were analyzed using meta-regression analysis.

Results: The clinical and radiographic success rates of coronal pulpotomy ranged between 92.2% and 99.4%, whilst for partial pulpotomy, the success rates ranged between 78.2% and 80.6%. Different pulp capping medicaments and restorative materials showed no significant effect on the success rates of coronal pulpotomy, but the former significantly (P < .05) affected the success rates of partial pulpotomy.
Conclusion: Coronal and partial pulpotomies demonstrated a high success rate in treating cariously exposed vital pulp of mature permanent molars. Further well-designed studies with longer follow-up periods are required to validate these findings. (Quintessence Int 2021;52:196–208; doi: 10.3290/j.qi.b912685)
