Summary

This study aims to evaluate whether the method of root surface preparation influences surgical outcomes. It will assess whether manual root instrumentation can be replaced by a less invasive erythritol air-polishing technique.

Conditions

• Gingival Recession

Interventions

Type	Name	Description
PROCEDURE	Erythritol Air-Polishing	Root surface preparation performed using erythritol powder air-polishing (EMS AIRFLOW PLUS) prior to root coverage surgery with a modified tunnel technique and subepithelial connective tissue graft.
PROCEDURE	Manual Root Instrumentation	Mechanical root surface preparation performed using manual Gracey curettes before root coverage surgery with a modified tunnel technique and subepithelial connective tissue graft.
