Abstract
Objective: The aim of this study was to compare postoperative pain following coronal
pulpotomy (CP) and root canal treatment (RCT) in mature molar teeth with irreversible
pulpitis.
Methods: Sixty permanent mature molars with irreversible pulpitis from 60 patients were
included. The teeth were randomly assigned to two groups (RCT or CP). RCT was performed
following standardized protocols. CP was performed to the level of the canal orifices, and
hemostasis was achieved with 2.5% sodium hypochlorite. Biodentine was placed as the
pulpotomy material. The teeth were restored with glass ionomer cement followed by
composite resin. Numeric Rating Scale (NRS) were recorded preoperatively and, at 3 and 7
days after the interventions. Fifty patients (25 each group) remained for the final analysis.
The data were statistically analyzed using the Independent t-test; Chi-square; Fisher’s exact
test, and Mann-Whitney U test. The significance level was set at 0.05.
Results: There was no significant difference between CP and RCT in the mean NRS scores
at 3- and 7-days post-operative (p > 0.05). The level of NRS was the highest at preoperative, decreased at 3- day and further decreased at 7-days post-operative. The
analgesic use was not different between the CP and RCT group.
Conclusions: There was no difference in the level and analgesic use for postoperative pain
at 3- and 7-days following CP and RCT in mature molar teeth with irreversible pulpitis.
