Assessment of alternative emergency treatments for symptomatic irreversible pulpitis: a randomized clinical trial

Aim To evaluate three emergency procedures for their ability to alleviate clinical symptoms associated with symptomatic teeth having signs of (at least) partial irreversible pulpitis. Methodology Sixty-six maxillary and mandibular molars were randomly assigned to a total pulpectomy group (TP; n = 22), partial pulpectomy group (PP; n = 22) or pulpotomy group (P; n = 22). Procedure durations were recorded. Patients answered a questionnaire on daily analgesic requirements and about clinical symptoms (pain intensity, chewing sensitivity and thermal sensitivity) after the anaesthetic effect had disappeared (Day 0) and on Days 1, 3 and 7 post-treatment. Results The total pulpectomy group was associated with the longest procedures (median, 24 min), followed by the partial pulpectomy and pulpotomy groups (P < 0.001 for all). In all three groups, pain intensity, thermal sensitivity and chewing sensitivity decreased significantly from the preoperative time-point to Day 7 (P < 0.001 for all). The total pulpectomy group reported greater reductions in pain intensity than the pulpotomy group between Days 0 and 7, Days 1 and 3, and Days 1 and 7 (P < 0.001 for all). No other intergroup differences were noted regarding reductions in pain intensity, and none were observed with respect to changes in prevalence of thermal sensitivity and chewing sensitivity. There were also no significant intergroup differences regarding the analgesic requirements throughout the 7days. Conclusion As emergency treatments for teeth having signs of irreversible pulpitis, pulpotomy, partial pulpectomy and total pulpectomy were comparable with respect to relieving clinical symptoms. Pulpotomy may be preferred because it requires significantly less time and is a simple technique that relieves symptoms quickly and effectively
