Abstract

IntroductionThe aim of this study was to compare the outcome and prognostic factors for partial and full pulpotomy in the management of mature teeth with spontaneous symptomatic pulpitis. MethodsThe study was a parallel double-blind randomized clinical trial; 200 carious mature permanent teeth with spontaneous symptomatic pulpitis were randomized using a block randomization technique to either partial pulpotomy (n = 99) or full pulpotomy (n = 101). Intraoperative assessment of the pulp under magnification was performed, hemostasis was achieved with a 2.5% sodium hypochlorite moist pellet, and NeoPUTTY (Avalon Biomed, Bradenton, FL) was the pulpotomy material. Preoperative pain levels were recorded and re-evaluated after 1 week. Clinical and radiographic evaluation was performed after 6 and 12 months. Data were analyzed using the chi-square test, the Wilcoxon rank test, and regression analysis. ResultsAt 1 week, immediate failure occurred in 4 cases in partial pulpotomy, and 196 of 200 subjects reported pain relief and were satisfied with the treatment with no significant difference. At 6 months, 6 teeth failed in the partial pulpotomy group and 1 tooth in the full pulpotomy group, with a higher success rate for full pulpotomy (98.96 vs 89.69, P = .003). At 12 months, the recall rate was 98% (96/200). Full pulpotomy was more successful than partial pulpotomy (98.98% [98/99] vs 84.53% [82/97], P < .001). Multivariate analysis revealed that the odds of success for full pulpotomy were 13.6 times higher than partial pulpotomy. Increased age and higher time to hemostasis were significantly associated with decreased odds of success. ConclusionsFull pulpotomy has a higher success rate than partial pulpotomy in the management of spontaneous symptomatic pulpitis. Hemostasis within 4 minutes in partial pulpotomy can be set as the cutoff point beyond which further tissue removal is indicated.
