Abstract
Introduction: Post-Operative pain is one of the most common issue that might happened during and after endodontic
treatment, this prospective randomized clinical trial evaluated the incidence and severity of Post-Operative pain
following root canal instrumentation using ProTaper Universal System, ProTaper Next system and WaveOne system.
Methods: Ninety patients with asymptomatic irreversible pulpitis on their permanent molar teeth selected and distributed randomly into three different groups of 30 patients each, to have access opening and instrumentation at same visit, those patients were fitted with inclusive criteria that we put for this study. Group 1 instrumented with ProTaper system, Group 2 instrumented with ProTaper Next system and Group 3 instrumented with WaveOne system, all systems strictly followed manufacturing instruction. The assessment of Post-Operative pain carried out at day 1, 2, 3 and 7, using Verbal Rating Scale (4-point scale). Verbal Rating Scale pain score compared and analyzed using Chi-Square test. Result: total score for Verbal Rating scale (scores recorded for 4 days) showed significant difference among the groups (P < 0.05), there was a significant difference between ProTaper Next group and the other two group (ProTaper group and WaveOne group) (P < 0.05), while there was Non-significant difference between ProTaper System and WaveOne System (P ≥ 0.05). Conclusion: ProTaper next system caused the lowest incidence and severity of Post-Operative pain, WaveOne system caused the highest incidence and severity of Post-Operative pain.
