Summary

This study tested two types of tooth-colored fillings to close multiple gaps between front teeth. 45 adults received either a thick injectable filling or a standard front-tooth filling. After one year, dentists checked how well each filling worked and looked. The goal was to see which material gives better results for closing gaps.
