Microneedling And Its Effect On Outcome Of Root Coverage With Coronally Advanced Flap Involving Isolated RT1 Maxillary Gingival Recession In Thin Gingival Phenotype: A Randomized Controlled Clinical Trial

Gingival recession (GR) is defined as the migration of the marginal tissue toward the apical of the cementoenamel junction. It is one of the most common mucogingival deformities requiring surgical correction. The rationale for treating buccal recessions are mainly aesthetic concerns, and clinical situations where unfavourable contour of the gingival margin might be an obstacle for proper plaque control. GRs are of 3 types with reference to interdental clinical attachment loss as Recession Type (RT) RT1, RT2 and RT3. Mid-buccal GRs have root coverage potential through periodontal plastic surgery procedures. Coronally positioned flap (CAF) is a simple and predictable treatment of gingival recession defects. It has been observed that a flap thickness of > 0.8 mm results in a covered root surface of 100%, whereas a flap thickness of < 0.8 mm results in partial root coverage in CAF procedure. Microneedling (MN), creates microinjuries that result in minimal superficial bleedings and create a wound-healing cascade from which various growth factors are released. MN as opposed to Connective Tissue Grafts is a non-surgical approach to increase gingival thickness, that results in significant changes in the Gingival Thickness of individuals with thin gingival phenotype.
