AIM: To assess the effect of occlusal reduction on postoperative pain following two visits root canal treatment in posterior mandibular teeth with symptomatic irreversible pulpitis and symptomatic apical periodontitis in a randomized clinical trial.
METHODOLOGY: This trial was conducted in the outpatient clinic of the Endodontic Department of the Faculty of Oral and Dental Medicine, Cairo University in Egypt. Forty-four-patients diagnosed with symptomatic irreversible pulpitis and symptomatic apical periodontitis were randomly assigned into two equal groups. The occlusal surfaces of teeth in the intervention group were reduced; whilst those assigned to the control group were left intact. Canal instrumentation was completed in the first visit using Revo-S rotary nickel-titanium files, and pain intensity was assessed using a visual analogue scale (VAS) at 6, 12, 24 and 48 h. Canal filling was completed 7 days later, and pain intensity was assessed at 6 and 12 h. A placebo was given and analgesics were prescribed to be administered in case of severe postoperative pain. Data were analysed using Independent t-test, chi-square and Fisher Exact tests.
RESULTS: The mean pain scores within the two groups were associated with a significant continuous decrease over time. Following both instrumentation and canal filling, the mean pain scores in the intervention group were lower than those in the control group at all follow-up periods and this difference was only significant at 12 h (P = 0.021 and P = 0.015, respectively).
CONCLUSIONS: Occlusal reduction reduced levels of postoperative pain in posterior mandibular teeth with symptomatic pulpitis and apical periodontitis only 12 h following both canal preparation and root filling.
