Evaluation of Postoperative Pain After Endodontic Retreatment Using Different Working Length Determination Methods: A Randomized Clinical Trial

December 10, 2024 updated by: öznur dişli
The aim of this study is to compare the effects of two different working length determination methods on the incidence of postoperative pain in single-rooted, single-canal teeth undergoing root canal retreatment (RCR). Sixty-four previously treated, single-rooted, single-canal teeth, which were determined to require RCR based on clinical symptoms and radiographic findings, were randomly and equally divided into two groups and included in the study. Two distinct working mechanisms of an integrated endodontic motor with an apex locator were used in our study. One method involved simultaneous determination of the working length during canal shaping, while the other method determined the working length with a hand file after the canal filling was removed. After the session in which the methods were applied and the working length was determined, participants' pain levels were recorded using a visual analog scale (VAS) at 6-12 hours and on days 1-2-3-4-5-6-7.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Evaluation of different working length measurement methods in endodontic treatment and postoperative pain.
Time Frame: 7 days
For the purpose of evaluating postoperative pain, the difference between two different working length measurement methods used during endodontic retreatment was analyzed. Postoperative pain was measured by visual analog scale (VAS) scores of the patients during the first 7 days after the procedure.
