- Abstract
This study investigated the effects of photobiomodulation (PBM) in acceleration of orthodontic movement of inferior molar uprighting movement. Thirty‐four individuals, with indication of molar uprighting movement for oral rehabilitation, were randomly divided in two groups: verticalization + PBM (808 nm, 100 mW, 1 J per point, 10 points and 25 J/cm2) or verticalization + PBM simulation. Elastomeric chain ligatures were changed every 30 days for 3 months. FBM was performed immediately, 24 h, 72 h, 1 and 2 months after activation. The primary outcome was the amount of uprighting movement. Secondary outcomes were pain, amount of medication, OHIP‐14 questionnaire, and cytokine IL‐1β. PBM group increase uprighting movement when compared to control after 3 months and modulate IL‐1β expression. For pain control, the amount of medication and OHIP‐14 no difference were found. This study suggests that PBM accelerates tooth movement during molar uprighting, due to modulation of IL‐1β during bone remodeling. [ABSTRACT FROM AUTHOR]
