Abstract

Objective: Evaluation of the 6-month clinical effectiveness of the coronally advanced flap (CAF) technique combined with porcine-derived acellular dermal matrix (PADM) in the surgical treatment of Type 1 gingival recession (Cairo 2011). Materials and Method: A randomized controlled clinical study was conducted on 16 Type 1 gingival recession lesions (Cairo). The control group included 8 recession lesions treated with the CAF technique, while the test group comprised 8 recession lesions treated with CAF + PADM. Treatment effectiveness was assessed based on clinical parameters, including recession depth (RD), recession width (RW), keratinized tissue height (HKT), gingival thickness (GT), and dentin hypersensitivity measured by the visual analog scale (VAS). These parameters were recorded preoperatively and 6 months postoperatively. Results: There was a statistically significant reduction (p<0.05) in RW and VAS values in both groups after 6 months. In the CAF + PADM group, GT significantly increased postoperatively and was significantly higher compared to the CAF group (p<0,05). However, the increase in HKT after 6 months was not statistically significant in either group (p>0.05). Conclusion: After 6 months, CAF + PADM demonstrated similar improvements in root coverage and dentin hypersensitivity reduction compared to CAF alone. However, PADM contributed to an increase in gingival thickness, reducing the risk of recession relapse and keratinized tissue deterioration postoperatively.
