Research is to compare and evaluate the clinical outcomes of the Connective tissue graft wall technique with modified coronally advanced flap to improve root coverage and clinical attachment levels in Miller's class III and IV gingival recession. The objectives is to assess the probing pocket depth reduction, clinical attachment level gain, patient esthetic evaluation, complete root coverage and mean root coverage. the control group will be treated with modified coronally advanced flap with connective tissue graft and enamel matrix derivative and the study group will be treated with modified coronally advanced flap with connective tissue graft wall and enamel matrix derivative. The total number of participants included will be 24 (Control-12; Study-12) with a 6 month follow up.
