| Low Level Laser Therapy | Other | Participants received low-level laser therapy applied to the temporomandibular joint region in addition to soft diet recommendations. Treatment was performed in 9 sessions according to the predefined laser protocol. Participants followed a soft diet regimen without receiving laser therapy and served as the comparison group. |
| Measure | Description | Time Frame |
|---|---|---|
| Change in temporomandibular pain intensity measured by the Visual Analog Scale (VAS) from baseline to the end of treatment and follow-up | Change in temporomandibular pain intensity was assessed using the Visual Analog Scale (VAS) from baseline to the end of treatment and follow-up. The Visual Analog Scale ranges from 0 to 10, where 0 indicates no pain and 10 indicates the worst pain imaginable. Higher scores represent greater pain severity. | 6 month |
