OR40 - Treatment Outcome of Partial and Full Pulpotomy in Cariously Exposed Mature Molars with Signs of Symptomatic Irreversible Pulpitis: 2-year Follow-up

Objectives: To assess the outcome of partial pulpotomy (PP) and full pulpotomy (FP) in cariously exposed mature molar teeth with signs of symptomatic irreversible pulpitis (SIP). Materials and methods: The study was designed as a double-arm, unicentric, superiority randomized controlled trial comprising 50 cariously exposed mature molar teeth. Teeth were randomly allocated in two experimental groups i.e. partial and full pulpotomy performed using Biodentine as the pulp capping material. Pain levels were recorded using VAS scale preoperatively, 24 hours, 48 hours and 7 days post-treatment. Teeth were clinically and radiologically evaluated at 3,6,12 and 24 months. Pulp sensibility testing was done at each visit. Results and statistics: Data was statistically analysed using chi-squared test, Mann-Whitney U test, Friedman’s test and Wilcoxon signed-rank test. Significance level was set at p< 0.05. Statistically significant reduction was noted in both the groups between the preoperative and post-operative pain scores. No significant difference was observed between two groups in terms of postoperative pain (p > 0.05). At 12-months follow-up, success rate of PP and FP was 88% (22/25) and 91.6% (22/24), respectively with one patient lost to follow-up. At 24 months, 38/44 attended follow-up. The success rate PP and FP at 24 months was 82.6% (19/23) and 90% (18/20), respectively (p>0.05).

Conclusions: PP and FP were comparable in terms of treatment outcome at two-year follow-up. PP can emerge as an alternative treatment modality for teeth presenting with signs of SIP, once validated with large sample size studies.
