Laser therapy will be performed for the intervention group while the laser probe will be placed on the area of the control group turned off. Due to the invisibility of the laser beam and the silence of the probe when turned on, patients will not notice whether the device is turned on or off. The outcome assessor will also evaluate patients in a separate room and will be blind to the patient group. The analyzer will also be blind to the group of patients because the names of the groups will not be in the data. N/A chin and lip anesthesia due to mandibular trauma. Intervention group: Patients who receive laser therapy on the area with neurosensory impairment in12 sessions with Gallium Aluminum Arsenide diode laser. Control group: Patients who do not receive any intervention and the laser probe will be placed on the area with neurosensory impairment turned off for 12 sessions.
