First, 15 cards will be labeled "A" and 15 cards will be labeled "B." Then, a random assignment list will be generated using a random number table. In this way, for the numbers in the table, they will be extracted as two digits. If the number is less than 50, "A" will be assigned, and if it is more than 50, "B" will be assigned. The cards will be placed in opaque envelopes in random order and sealed. The envelopes will be placed in a box. At the start of participant registration, each participant will randomly select an envelope from the box and give it to the researcher in charge of randomization. The person in charge will open the envelopes and record the group assigned to each individual, Blinding description: The study will be double-blind, and the patient and the person assessing the outcomes will not be aware of the groupings, and only the person applying the laser and the person responsible for randomization will be aware of the grouping. Also, the laser device will be turned on in the control group to make its sound, but the laser will not be activated, and since all patients' eyes will be closed to protect them from the laser light, they will not notice whether the laser is active or not. 3 Temporomandibular joint disorders. Intervention 1: Intervention group: Supportive treatments for temporomandibular joint disorders including warm compresses, muscle relaxants Methocarbamol 500 mg every 8 hours, Ibuprofen 400 mg every 12 hours, habit modification and stretching exercises, along with laser therapy with a low-level diode laser with a wavelength of 980 nm. Intervention 2: Control group: Supportive treatments for temporomandibular joint disorders including warm compresses, muscle relaxants Methocarbamol 500 mg every 8 hours, Ibuprofen 400 mg every 12 hours, habit modification and stretching exercises, along with inactive laser.

The pain level. Timepoint: At the (first, fifth, and tenth) sessions. Method of measurement: It will be assessed using the visual analogue scale, where the most severe and unbearable pain is rated as 10, and complete absence of pain is rated as 0. The measurement will be performed at all three stages while the patient is at rest. Mouth opening level. Timepoint: At the (first, fifth, and tenth) sessions. Method of measurement: Maximum mouth opening will be measured using a ruler. The distance between the incisal edges of the upper and lower centrals will be measured at maximum opening. The measurement of maximum mouth opening will be repeated three times and the average of the results will be recorded.
