Summary

This study involved 24 adults with receding gums to see if adding an enamel protein to a standard gum graft procedure improves results. The standard method uses a tissue graft placed under the gum with a small tunnel. Half the participants also got the enamel protein. Researchers measured gum coverage, attachment, and thickness at the start and after 6 months.
