Comparative Evaluation Of Postoperative Pain And Periapical Healing After Root Canal Treatment Using Three Different Base Endodontic Sealers – A Randomized Control Clinical Trial

Abstract

Background: The aim of the present study was to evaluate and compare the postoperative pain and periapical healing after root canal treatment using three different base endodontic sealers. Material and Methods: Primary root canal treatment was initiated in 80 patients diagnosed with necrotic pulp and apical periodontitis, cleaning and shaping was completed in two visit and different base endodontic sealers were used for obturation were selected based on the random allocation of the participants to the following groups; Tubli-Seal, Nineteen NT apexseal, AH Plus and Maarc ceraseal B sealer. Postoperative pain was recorded by using verbal rating scale at 24 h, 48 h, 72 h and 7 d after obturation. Digital periapical radiographic evaluation was done to assess rate of periapical healing at baseline, 1, 3 and 6 months. Statistical analysis was done using Kruskal Wallis test and one-way ANOVA. Results: The mean difference in the size of periapical lesions for Tubli-Seal (3.96,7.88), Nineteen N T apexseal( 6.38,10.60) AH Plus (6.34,11.99) and Maarc ceraseal B sealer (5.51,12.39) at 3 months and 6 months respectively. In Tubli-Seal group, at 24 h, 5.3% of patients showed no pain, 68.4% showed mild pain and 26.3 % showed moderate pain; at 48 h, 84.2% of patients showed no pain, 10.5% showed mild pain and 5.3 % showed moderate pain; At 72 h, 84.2% of patients showed no pain, 10.5% showed mild pain and 5.3 % showed moderate pain; At 7 d, none of the patients reported with pain. Conclusions: Maarc Cera Seal B sealer showed less postoperative pain compared to AH Plus, Nineteen NT and Tubli-Seal and showed better periapical healing compared to AH Plus and Tubli-Seal at 3 and 6 months intervals respectively
