Abstract

Objective: To compare the clinical efficacy of 2.5% non-heated sodium hypochlorite and 2.5% heated sodium hypochlorite as irrigation to control postoperative pain in single visit root canal treatment. Study Design: Comparative analytical study Place and Duration: Operative dentistry department of Liaquat University of Medical and Health Sciences, Jamshoro for 6 months duration from March 2017 to September 2017. Material and Methods: A total of 60 patients with single rooted maxillary and mandibular permanent teeth were randomly allocated into two groups. 30 patients were in group A and treated with non heated sodium hypochlorite solution and 30 patients in group B were treated with 2.5% heated sodium hypochlorite solution. In both groups, the level of pain was measured postoperatively after 48 hours by using Heft Parker visual Analog Scale of 10 and information was collected on Performa. Results: The average age of the patients was 28.62±6.06 years. There were 40(66.7%) male and 20(33.3%) female. Pain was reduced in both groups but there were no significant difference in reduction of pain between groups (p=0.640). Conclusion: Severity of pain was not statistically significant between groups. At 48 hours, Pain was reduced in both groups but there were no significant difference in reduction of pain between groups. Heated sodium hypochlorite to relieve postoperative pain, it should be new trend for recommendation for treatment of irreversible pulpitis in single visit root canal treatment.
