Comparison between the mean postoperative pain score with two different file systems in patients with irreversible pulpitis-a clinical study in Altamash Institute of Dental Medicine.

Abstract

Endodontic Pain if occurs after few hours or days after the treatment indicates a poor pathosis and a bad prognosis in long term, due to this a newer generation of instruments for canal treatment has been introduced from Ni-Ti alloy which has even better ability to shape narrow and curved root canals, without causing aberration. To compare the mean postoperative pain score after manual SS (stainless steel) K-files and mechanical Ni-Ti rotary path files in patients with irreversible pulpitis. Study Design: Randomized controlled trial. Setting: Department of Operative Dentistry, Altamash Institute of Dental Medicine, Karachi. Period: 6 months from 01-10-2017 to 30-03-2018. Materials and Methods: Total 60 patients of irreversible pulpitis with moderate pain score ≥5 were included and divided equally in manual stainless-steel k-files and mechanical Ni-Ti rotary path files groups. Treatment was started with local anesthesia. Patients were recalled after 24 hours and the level of postoperative pain was examined. T-test was applied to compare the outcome in both groups. Stratification was done using t-test and P value ≤0.05 was significantly considered. Results: The mean pre-treatment VAS in group-A and group-B was 7.16±1.44 and 7.86±1.38 respectively. Mean post-treatment VAS in group-A and group-B was 2.33±1.02 and 1.10±0.66 respectively. A significant difference between the pre and post op pain was noted between the two groups, when compared after 24hours by using VAS. Conclusion: Mean post-operative pain score was significantly less with NiTi rotary path files as compare to manual stainless steel K-files.
