Summary

This study looks at whether adding hyaluronic acid (a natural gel) to standard gum graft surgery helps cover exposed tooth roots better and improves healing. Forty adults with receding gums will be randomly assigned to get the graft alone or with the gel. The main goal is to measure how much root coverage is achieved after 6 months.
