This study was designed to investigate the effectiveness of diadynamic current, one of the electrotherapy methods added to rehabilitation in the treatment of bruxism. Individuals over the age of 18 diagnosed with bruxism will be randomly assigned to one of the following groups using the sealed envelope method: rehabilitation program (control group) or rehabilitation program combined with diadynamic current (experimental group). The intervention will consist of an exercise program conducted jointly for the experimental and control groups. Participants will be given a structured exercise program to be performed in person 3 days a week for 6 weeks. In addition to the exercise program, the experimental group will receive diadynamic current treatment at each session. Pain intensity will be assessed using the Visual Analog Scale (VAS), pressure pain threshold with an algometer, muscle strength with a hand-held dynamometer, bite force with a pinch meter, maximal mouth opening with a caliper, and head posture with the craniovertebral angle. Oral habits will be evaluated using the Oral Behavior Checklist, and anxiety levels will be assessed with the State-Trait Anxiety Inventory (STAI).
