Photobiomodulation for Postoperative Pain
What You Need to Know Before You Apply
What is the purpose of this trial?
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.

Are You a Good Fit for This Trial?
This trial is for adults who need a nonsurgical root canal due to painful tooth conditions like abscess or inflamed dental pulp. People with these symptoms and no major health issues can join.Inclusion Criteria

- Photobiomodulation
Trial Overview
The study compares standard root canal treatment plus real laser therapy (photobiomodulation) versus standard care with a fake laser procedure. Participants are randomly assigned, and neither they nor the researchers know which group they're in.

Experimental Treatment
Placebo Group
Participants will receive standard nonsurgical root canal treatment followed by adjunctive photobiomodulation using the Fotona LightWalker Nd:YAG laser immediately after obturation.
Participants will receive standard nonsurgical root canal treatment followed by a simulated laser procedure. The laser handpiece will be positioned identically and treatment steps will be replicated, but laser energy will not be delivered.
