U.S., Nov. 19 -- ClinicalTrials.gov registry received information related to the study (NCT07233590) titled 'The Effect of Apical Patency on Postoperative Pain Following Root Canal Treatment' on Nov. 14.
Brief Summary: The goal of this randomized controlled clinical trial was to evaluate whether implementing apical patency affects the intensity of postoperative pain after single-visit root canal treatment in asymptomatic, vital, single-rooted teeth.
The main question it aims to answer is:
Does maintaining apical patency by gently extending a #10 K-file 1 mm beyond the working length during canal shaping influence postoperative pain compared with instrumentation confined within the working length?
In the patency group, the working length...
