Gingival Recession (RT1) Treatment With Different Gingival Augmentation Surgeries

This parallel arm randomized controlled clinical trial study will include systematically free patients with thin gingival phenotype. They will be randomly allocated to three equal groups. Group A (test group, n=10) will receive non-surgical periodontal treatment and connective tissue graft using tunneling technique, Group B (test group, n=10) will receive non-surgical periodontal treatment and partially de-epithelized free gingival graft, while group C (control group, n=10) will receive non-surgical periodontal treatment only. After 3, 6 and 12 months gingival biotype will be clinically assessed (1ry outcome). This parameter will be recorded at baseline, 3, 6 and 12 months. The 2ry outcomes will include recording of recession depth, plaque index, bleeding on probing, keratinized tissue width . Postoperative pain and swelling will be recorded daily by the patient for the 1st two weeks post-surgically. Postoperative instructions and medication will be given to the patient. All readings will be carried out by a calibrated outcome assessor who will be masked. Follow-up will be performed to assess the outcomes and to ensure performing proper oral hygiene. Data collected will be tabulated and statistically analyzed.

• Connective tissue graft (Procedure): non-surgical periodontal treatment and connective tissue graft
• Free gingival graft (Procedure): will receive non-surgical periodontal treatment and partially de-epithelized free gingival graft
• Non surgical (Procedure): non-surgical periodontal treatment only

Primary outcomes

• Gingival phenotype change [at baseline 3,6 and 12 months]: determination of the change in gingival thickness in mm using periodontal probe

Secondary outcomes

• Keratinized tissue width [at baseline 3,6 and 12 months]: determination of Keratinized tissue width in mm using periodontal probe
• Root coverage esthetic score (RES) [at baseline 3,6 and 12 months]: It is a scoring system to assess the level of gingival margin (GM),marginal tissue contour (MTC),Soft tissue texture, Mucogingival alignment (MGJ),Gingival color The score is 0,1 and 3 where 0 is the minimum and 3 is the maximum
