Abstract
ABSTRACT Objective To evaluate the effect of low-level laser therapy (LLLT) on pain intensity (PI) and chewing performance (CP) in systemic lupus erythematosus (SLE) patients with myogenic temporomandibular disorder (TMD). Methods Ninety-one patients were randomly allocated to three groups: Group L (intervention), Group P (placebo), and Group C (control). Outcomes were PI (assessed with visual analog scale (VAS)) and CP (assessed with the geometric mean diameter (GMD) of crushed test food). Measurements were performed at T0 (before the LLLT), T1 (immediately after the LLLT), and T2 (1-month follow-up). Data were analyzed using Generalized Linear Models, Kruskal-Wallis, and Friedman tests. Results For T1 and T2, Group L demonstrated the lowest values for both GMD (6283.7 ± 257.2 µm; 6382.7 ± 303.7 µm) and VAS (5;6) (p < 0.001). Conclusion LLLT was an effective therapeutic approach in reducing pain and improving CP for one month in SLE patients with myogenic TMD.
