Modified Coronally Advanced Tunnel for Mandibular Lingual Root Coverage

This study will follow adults who have gum recession on the tongue side of the lower teeth. Participants will receive a gum surgery called the Modified Coronally Advanced Tunnel technique with a connective tissue graft taken from the roof of the mouth. The study will include 20 participants and will follow them for up to 24 months after surgery. The main outcome is how much of the exposed root is covered 6 months after surgery. The study will also measure gum thickness, gum width, tooth sensitivity, healing, patient comfort, satisfaction, and three-dimensional soft tissue changes using intraoral scans.
