Effects of Intracanal Cryotherapy Applications on Postoperative Pain After Nonsurgical Root Canal Retreatment in Teeth with Symptomatic Apical Periodontitis: Randomized Controlled Clinical Trial
To evaluate the effectiveness of intracanal cryotherapy in reducing postoperative pain after root canal retreatment in symptomatic apical periodontitis.
Conducted a randomized controlled clinical trial
Applied intracanal cryotherapy during root canal retreatment
Measured postoperative pain levels after the procedure
Significant reduction in postoperative pain levels reported with cryotherapy
Patients receiving cryotherapy experienced less pain compared to the control group
Cryotherapy demonstrated effectiveness in symptomatic cases of apical periodontitis
Abstract
The application of intracanal cryotherapy in teeth that need root canal retreatment with symptomatic apical periodontitis may be an effective method for reducing postoperative pain levels.
