Abstrakt:	Background: Despite extensive research on the use of low‐power lasers for TMD treatment, the extent of their effectiveness remains uncertain. Objective: This study aimed to investigate the therapeutic or placebo effect of LLLT for TMD, and to compare it with standard treatment methods. A unique aspect of this study was the inclusion of a control group that received only standard treatment, allowing for an assessment of the placebo effect of LLLT. Methods: A total of 42 patients with TMD were referred to Kerman Dental School Pain Clinic and were randomly assigned to three groups: group A received LLLT, group B was a placebo group and group C was a control group that received only standard treatment. The laser groups received gallium‐aluminium‐arsenide laser treatment twice a week for 10 sessions. Patients' jaw movement rate indicators and VAS index were evaluated at the start of treatment, and indicators were re‐recorded every week for 5 weeks. SPSS 21 was used for statistical analysis, including ANOVA and Tukey's post hoc tests for inter‐group comparisons. The repeated measurement test was used to analyse the data. Results: All groups showed significant improvement in VAS indicators (p =.0001), lateral jaw movements (p =.0001), forward jaw movement (p =.007) but not for maximum mouth opening. No significant difference was observed between the groups at the end of the study (p =.000). Conclusion: Our study provides insights into LLLT's effectiveness for TMD, suggesting it cannot replace standard treatment alone. These findings contribute to the literature and emphasise the importance of including a control group in future studies to assess the placebo effect of LLLT. [ABSTRACT FROM AUTHOR]
