Brief Summary

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.

Conditions

This Study Compares the Effects of Two Working Length Methods on Postoperative Pain in Single-rooted, Single-canal Teeth During Root Canal Retreatment

Outcome Measures

Primary Outcomes (1)

• Evaluation of different working length measurement methods in endodontic treatment and postoperative pain.

  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.

• Individuals with preoperative pain rated 50 or lower on the 100 mm VAS scale

You may not qualify if:

• Individuals with systemic diseases or allergic reactions. Pregnancy and breastfeeding. Teeth with open apex. Teeth with internal or external root resorption. Patients who have taken analgesic, anti-inflammatory, or antibiotic medications within the last twelve hours.
• Teeth with broken instruments in the canal. Individuals with bruxism problems.
