The goal of this randomized controlled study is to compare laser acupuncture versus modified physical therapy in controlling bruxism in children. The main questions aim to answer are:

• Laser will decrease tempro-mandibular joint pain from bruxism more than modified physical therapy?
• Laser will decrease muscles activity from bruxism more than modified physical therapy? Children took 6 sessions of either laser acupuncture or modified physical therapy Researchers compared laser acupuncture versus modified physical therapy to see if any decrease in tempro-mandibular joint pain and muscles activity from bruxism

The children participated in the study as bruxers according to the American Association of Sleep Medicine (AASM) diagnostic criteria [ Sixteen children will be randomly allocated to two groups of 8 individuals each: Group one: laser acupuncture, Group two: electromyography biofeedback training.

Pain will be measured by Visual Analogue scale; VAS (primary outcome)and muscle activity will be measured by Electromyography (Secondary outcome) of temporalis and masseter muscles. Measurements will be taken preoperatively and after 8 weeks.](streamdown:incomplete-link)
