Objective: This study aimed to evaluate the effect of photobiomodulation on restricted mouth opening and pain relief in painful temporomandibular patients by using two wavelengths of diode laser. Material and Methods: In this study, thirty-six participants—ages 18 to 45 yeas—who suffered from restricted mouth opening, pain in the temporomandibular joint area and tenderness in the temporal and masseter muscles were divided into two groups: Group A (n = 15) received 980 nm laser therapy, and Group B (n = 15) received 635 nm laser therapy. Six participants were excluded. Over the course of two weeks, each group had six therapy sessions. The maximal mouth opening was measured by digital caliper and the pain severity was evaluated using the Visual Analog Scale. The mouth opening and pain scale of the groups were then evaluated statistically using Multiple Wilcoxon sign rank adjusted by Dunn-Bonferroni method, and Tukey’s HSD tests. The significance level was set to 0.05. Results: The outcomes demonstrated that there were notable improvements in mouth opening and discomfort reductions in both groups. The 980 nm treatment displayed a consistent reduction from baseline, with statistically significant differences between all-time points. The 635 nm treatment showed a more pronounced reduction, especially between baseline and six weeks or one month, but no significant difference between six weeks and one month. Conclusion: This study demonstrated the significant impact of the therapeutic efficacy of diode laser wavelengths on the management of masticatory disorders and myofascial pain.
