Effect of Different Root Canal Disinfection Procedures on Postoperative Pain

Effect of Different Root Canal Disinfection Procedures on Postoperative Pain: A One-Week Follow-Up Clinical Study

This clinical study evaluated the effects of different root canal disinfection procedures on postoperative pain. Patients requiring root canal treatment received one of several disinfection methods. Postoperative pain was assessed at 6,24, 48, 72 hours and on the 7th day using a standard pain scale. The aim of the study was to identify which method resulted in the least discomfort. Participation involved a single treatment session and short-term follow-up for pain measurement.
