Summary

This study looked at how well smartphone apps and a special ring (Belun Ring) can measure sleep quality in adults getting braces or other orthodontic treatment. 52 people from Case Western Reserve University's dental clinic took part. They answered sleep questionnaires and used the devices at home. The goal was to see if these tools can help spot sleep problems like snoring or sleep apnea in dental patients.
