Summary

This study compares two types of dental cement used to place tooth-colored inlays (fillings) in cavities of back teeth. Fifty adults with large cavities or broken fillings will receive an inlay and be followed for 18 months to see which cement performs better in terms of strength, appearance, and gum health. The goal is to find a simpler, more reliable way to restore damaged teeth.
