Summary

This study compares two ways to treat deep bone defects in the gums caused by gum disease. One method is a minor surgery (MIST) and the other is a deep cleaning (GBT), both combined with a substance made from the patient's own blood (platelet-rich fibrin) to help healing. About 36 adults with a single deep gum bone pocket will take part. The goal is to see which approach leads to more bone fill and healthier gums.
