Summary

This study tested whether preheating a special tooth-colored filling material before placing it in cavities helps it last longer and cause less tooth sensitivity. Seventy adults with cavities on both sides of their mouth received one preheated and one non-preheated filling. Over 12 months, researchers checked how well the fillings stayed in place, their edges, and any pain reported. The goal is to find a simple way to improve everyday dental care.
