Summary

This study tested whether a gel made from chitosan (a natural substance) can better preserve the jawbone after a tooth is pulled, compared to letting the socket heal on its own. Twenty-six adults with at least one hopeless tooth in the back of the jaw participated. Researchers used CT scans to measure bone width changes over six months.
