Effect Of Microneedling With Coronally Advanced Flap For Management of RT1 Gingival Recession In Thin Gingival Phenotype

The goal of this clinical trial is to explore the effect of microneedling to increase the gingival tissue thickness which could improve the outcome of root coverage in coronally advanced flap procedure in thin gingival phenotype. The main question it aims to answer is that : Does the use of microneedling procedure followed by coronally advanced flap has similar outcomes of root coverage in recession type 1 (RT1) gingival recession i.e. buccal gingival recessions without interdental clinical attachment loss in thin gingival phenotype as compared to coronally advanced flaps with connective tissue graft. Systemically healthy patients having isolated upper RT1 gingival recession will be assigned into two groups. Microneedling will be performed in one group (4 sessions each at a 10 days interval) followed by coronally advanced flap operation (at an interval of 2 months) and coronally advanced flap with connective tissue graft will be performed in the other group. Follow-up will be done at 1 month, 3 months and 6 months for evaluation of primary and secondary outcomes.
