Summary

This study examined 180 adults to see if the shape of their gums and their oral habits (like brushing force or teeth grinding) are linked to non-carious cervical lesions — wear on teeth not caused by cavities. Participants filled out a questionnaire and had a dental exam. The goal was to better understand these relationships, not to test a treatment.
