Summary

This study looked at four different techniques for placing tooth-colored composite fillings in back teeth with cavities. Fifty patients received 200 fillings and were followed for 2 years to see how well the fillings held up, especially around the edges. The goal is to find the best method for long-lasting dental restorations.
