The Influence of Three Root Canal Irrigation Methods on PostThe Influence of Three Root Canal Irrigation Methods on PostOperative Pain “Randomized Clinical Trial”

Abstract

Endodontics Aim: This clinical study was designated to evaluate the influence of three root canal irrigation activation methods on postoperative pain using the Visual Analogue Scale VAS. Material and Methods: 78 patients having symptomatic irreversible pulpitis in mandibular first molar with no periapical involvement. ProTaper Next rotary files were used for root canal preparation, the cases were then divided randomly into three equal groups based on the final irrigation agitation technique, with each group having 26 cases. (n=26 ). Group A: received irrigation with 2.6% sodium hypochlorite with NaviTip (31- gauge 27 mm) with double side port irrigator tip (SVN) without any agitation; Group B: received irrigation with 2.6% sodium hypochlorite with final mechanical agitation of irrigation with ultrasonic device activation (Endo ultra) (PUI) Group C: received irrigation with 2.6% sodium hypochlorite with final mechanical agitation of irrigation with sonic device activation (EDDY). Using a Visual Analogue Scale (VAS), postoperative pain was evaluated at intervals of 6,12,24,72 hours and 7 days. Results: Overall results of study showed ,At the first (6,12,24 hours) there was a significant difference between the groups in pain incidence and intensity where group A showed more pain scores than group B and group C. At (48, 72 hours and 7 days) there were no significant difference between the groups where pain scores declined among the groups till it reaches nearly score (0) at 7 day. Conclusion: group A (SVN) showed highest postoperative pain in the first 24 hours in comparison with the other groups, where the pain level decreased gradually in all groups after 24 hours.
