Official title
Effect of Adjunctive Photobiomodulation on Mechanical Allodynia and Postoperative Pain Following Nonsurgical Root Canal Treatment in Teeth With Symptomatic Apical Periodontitis
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This randomized, double-blind controlled clinical trial will evaluate whether adjunctive photobiomodulation improves recovery after nonsurgical root canal treatment in adults with teeth diagnosed with symptomatic apical periodontitis. Participants will receive standard nonsurgical root canal treatment and will be randomized to adjunctive photobiomodulation using the Fotona LightWalker Nd:YAG laser or to an identical simulated laser procedure without laser energy delivery. The study will evaluate mechanical allodynia using maximum occlusal force measurements comparing the treated tooth with the contralateral asymptomatic tooth. Postoperative pain will also be assessed using the Numeric Rating Scale after percussion testing.
