Abstract
AIM: To evaluate the association between apical patency and postoperative pain in posterior teeth with pulp necrosis and apical periodontitis.
METHODOLOGY: Sixty-eight patients requiring primary root canal treatment in mandibular first molars with necrotic pulps and apical periodontitis were included. The patients were randomly allocated to one of the two groups: patency (n=34) and non-patency (n=34). After administering local anaesthesia, root canal preparation was done using ProTaper rotary instruments. A size 10 K-file was used as patency file and carried 1 mm beyond the working length (WL) between each instrument change in the patency group, while it was carried up to WL in the non-patency group. Patients were asked to record their pain experience on a pain chart daily for seven days. Three patients (two in the patency group, one in the non-patency group) did not return with completed pain charts on the subsequent visit, resulting in a total of 65 patients for the final analysis (Patency, n=32; Non-patency, n=33). Data was analysed using Chi Square test, t-test, Mann Whitney test and Wilcoxon Signed Ranks test.
RESULTS: Overall, 43.1% of the patients experienced postoperative pain. The patency group had less incidence of pain (34.4%) as compared to the non-patency group (51.5%), but the difference was not significant (P = 0.163).
CONCLUSION: Maintenance of apical patency during chemomechanical preparation had no significant influence on postoperative pain in posterior teeth with necrotic pulps and apical periodontitis. This article is protected by copyright. All rights reserved.
