Evalution of Postoperative Pain With Resin Based Sealer vs Zinc Oxide Eugenol Sealer After Single Visit Endodontic

A total of 100 patients requiring endodontic treatment for permanent molar in accordance with the inclusion and exclusion criteria will be selected for the study. The treatment and study design will be explained to the patients in their own comprehendible language and a written informed consent will be obtained from the voluntary patients who participated in the study. A cold test and electric pulp-test was used to assess pulp vitality. Based on clinical and radiographic findings, the patients diagnosis of irreversible pulpitis. Patients will be randomly divided into two groups Group A = resin based sealer and Group B = Zinc oxide eugenol sealer. Prior to treatment the patients will be instructed how to complete a visual analog scale (VAS) to determine their pain score. The VAS included a 10 cm straight horizontal line numbered at each centimeter with the following criteria.Local anesthetic with 2% lignocaine containi Local anesthetic with 2% lignocaine containing 1:80000 epinephrine will be administered to each patient after recording preoperative pain levels . A rubber dam will be applied. The endodontic access cavities will be prepared with endo access burs .Working length will be established with #10 K file and the root canal will be instrumented with one shape rotary system up to #25.6% under copious irrigation with 3% sodium hypochlorite and normal saline. Before obturation root canals will be final rinse with 5 ml of 17% EDTA solution. In both groups, the root canal will be dried with paper points and obturated using gutta-percha cones and Resin based sealer/zinc oxide eugenol sealer. Coronal access cavities will be restored with direct composite restorations using dentinal adhesives and universal composite resin . Postoperative VAS scores will be recorded after 24 h and 48 h to determine their post-operative pain.
