Assessment of Post-operative Pain after using EdgeFile X7 and Protaper Next Rotary Systems in Patients with Symptomatic Pulpitis in Mandibular Molars: A Randomized Controlled Clinical Trial

AIM: The aim of the study was to evaluate the incidence of post-operative pain and analgesics intake after single-visit endodontic treatment using Edge File X7 and ProTaper Next (PTN) rotary files in mandibular molars having symptomatic pulpitis.METHODS: The study included 60 patients complaining of symptomatic pulpitis in mandibular molar teeth. After confirming the diagnosis clinically and radiographically, patients were assigned into two equal groups; Group (I): Instrumentation was done with Edge File X7 (EF) rotary files and Group (II): Instrumentation was done with PTN rotary files. The patients underwent standardized single visit endodontic treatment procedures using 2.5% sodium hypochlorite for irrigation. Modified visual analogue scale was used to access pain preoperatively, and then postoperatively after 6, 12, 24, 48, and 72 h. An analgesic (ibuprofen 400 mg) was prescribed to the patient who suffered from persistent pain. The incidence and/or number of analgesic tablets intake were recorded. Data of pain score were compared using Mann–Whitney U test for intergroup comparisons and Freidman’s test followed by Dunn’s post hoc test for intragroup comparisons.RESULTS: No statistically significant difference was detected between EF and PTN groups regarding the incidence and intensity of pain at different time intervals (p > 0.05). There was a significant reduction in the mean VAS score through the follow-up periods in both groups (p < 0.001). The incidence of analgesic intake was not significant in both groups.CONCLUSION: The incidence of post-operative pain and the analgesic intake in terms of frequency and quantity were found to be similar with both rotary systems for all the post-operative time points.
