Summary

This study looks at how well a special type of dental filling called Giomer works in people with and without diabetes. Researchers will place fillings in cavities on the tooth neck and check them over 18 months to see if they stay in place and prevent new decay. The goal is to understand if diabetes affects how long these fillings last.
