Comparison of Root Coverage Outcomes by NORD Flap Versus Subepithelial Connective Tissue Graft in RT1 Gingival Recession

"After undergoing phase one of periodontal therapy, patients will be recalled after four weeks for root coverage surgery. Patients will be randomly allotted to either group by stratified block randomization after taking baseline measurement with respect to periodontal phenotype(PP) \[using transparency of periodontal probe through the gingival margin, when probe is visible, thin PP and when not visible, thick PP\] so that patients with thick and thin PP get an equal chance of being allocated to NORD and Sub epithelial connective tissue group.~1. Group 1(NORD group)- Patients treated with NORD flap~2. Group 2 (Sub epithelial connective tissue group)- Patients treated with sub epithelial connective tissue graft Patients will be followed up after 1 month,6, 12 and 15 months. 30 patients belonging to thin phenotype will be followed up as separate cohort for period of one year to evaluate phenotype modification."
