Conditions

Gingival Recession

Brief summary

This study evaluates whether adding 0.8% hyaluronic acid (HA) to connective tissue grafting and coronally advanced flap surgery improves clinical and esthetic outcomes in the treatment of gingival recession. Adult patients with Miller I-II or Cairo RT1 recession defects will be randomly assigned to receive CTG alone or CTG with adjunctive HA. Mean root coverage at 6 months is the primary outcome, while secondary measures include gingival thickness, clinical attachment level, esthetic scores, postoperative morbidity, and quality of life. The study aims to determine whether HA enhances soft tissue healing and root coverage predictability compared with conventional CTG.

Interventions

BIOLOGICALHyaluronic Acid (0.8%) - Applied over CTG before flap closure (Test group only).

A 0.8% hyaluronic acid (HA) gel is applied to the connective tissue graft (CTG) before flap closure during the coronally advanced flap (CAF) procedure. The HA gel is used as an adjunctive biologic material to potentially enhance wound healing, soft tissue thickness, esthetic outcomes, and overall root coverage performance

PROCEDUREConnective Tissue Graft + Coronally Advanced Flap (CTG + CAF)

A standardized coronally advanced flap (CAF) procedure combined with a subepithelial connective tissue graft (CTG) is performed to treat gingival recession defects. The surgical protocol includes flap elevation, graft harvesting and placement, and flap advancement and suturing.
