Review of the effectiveness of biofeedback for treating Bruxism

— by

A new study published this week (January 2023) suggests that biofeedback may be an effective treatment option for individuals suffering from bruxism (teeth grinding) during the day.

The study, which was a systematic review of existing research on the topic, found that biofeedback, specifically auditory and visual biofeedback, can reduce the level of masticatory muscle activity in individuals with bruxism.

However, it’s important to note that the studies included in this review had a high risk of bias and small sample sizes, which limits the strength of the findings.

Additionally, the study suggests that future research should have larger sample sizes and be conducted with high methodological standards to avoid important bias associated with inappropriate randomization, blinding, and deviations from intended interventions.

Furthermore, it is recommended that future studies should also look into other clinically relevant outcomes such as pain, quality of life, and disability.
