Protocol for low-level laser therapy (LLLT) to control post-endodontic treatment pain in patients with apical periodontitis: a randomized controlled trial.

ABSTRACT:

Background

Pain after endodontic therapy affects from 2.5 to 60% of patients and may significantly impacts patient's quality of life and adherence to dental treatment. This blind clinical trial protocol was designed to evaluate the analgesic effect of low-level laser therapy (LLLT) and its impact on post-operative pain and on quality of life (QoL) in patients with apical periodontitis (AP) submitted to root canal treatment (RCT).

Methods

116 patients will be selected. RCT will be performed using the ProTaper Next system. Patients will be randomly allocated into 2 groups: control (naproxen prescription) and test (LLLT). Post-operative pain levels will be assessed through numeric raking scale (NRS) before intervention and at 6 h, 12 h, 24 h and 72 h after endodontic procedures
