Inclusion criteria
Inclusion criteria: Children of both sexes; aged between 6 and 12 years; diagnosis of sleep bruxism confirmed by parental or legal guardian report of teeth grinding or clenching sounds during sleep and the presence of compatible clinical signs; ability to understand and cooperate with study procedures; whose parents or legal guardians agree to and sign the Informed Consent Form; assent provided by the child through signing the Assent Form.
Exclusion criteria
Exclusion criteria: Children with neurological, psychiatric, genetic, or developmental disorders; children with craniofacial anomalies or syndromes; current use of medications that may interfere with sleep patterns, muscle activity, pain perception, or emotional status; previous or ongoing treatment for sleep bruxism; presence of acute dental pain, active oral infections, or temporomandibular disorders requiring immediate treatment; history of photosensitivity or contraindications to laser therapy.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Expected primary outcome: reduction in resting electromyographic activity of the masticatory muscles following the intervention. Muscle activity will be assessed via surface electromyography before the start of treatment and after the completion of the 12 intervention sessions.;Primary outcome: a reduction in sleep bruxism was observed, as assessed by the Bruxism Screening Questionnaire. A significant reduction in sleep bruxism was observed in the Red Laser and Infrared Laser groups after 12 sessions of photobiomodulation compared to the baseline assessment. | — |
Secondary
| Measure | Time frame |
|---|---|
| Expected secondary outcome: To evaluate the effect of photobiomodulation on muscle pain upon palpation in children with sleep bruxism. Improvements are expected in muscle pain, sleep quality, daytime sleepiness, health-related quality of life, stress levels, anxiety, and depression.;Secondary outcomes observed: significant improvement in sleep quality across all groups; a reduction in the oxygen desaturation index in the Placebo and Infrared Laser groups; and improvements in minimum heart rate in the Red Laser group and maximum heart rate in the Infrared Laser group. No differences were observed regarding electromyographic activity, daytime sleepiness, health-related quality of life, or sleep disturbances. | — |
