Summary

This study looked at whether people with bruxism (teeth grinding or clenching) have worse lung function, breathing muscle strength, balance, and sleep quality compared to healthy people. Researchers tested 34 adults using breathing tests, balance assessments, and sleep questionnaires. The goal was to understand if bruxism is linked to these other health issues, not to test a treatment.
