Abstract

Objective: Clinical evaluation of Coronally Advanced Flap (CAF) with or without Porcine Acellular Dermal Matrix for the treatment of gingival recessions type I (Cairo 2011). Materials and methods: Randomized controlled clinical study was conducted on 16 gingival recession lesions type 1 (Cairo 2011) with 8 gingival recession lesions treated with only CAF flaps (control group) and 8 gingival recession lesions treated with CAF flap + MucodermÒ (PADM) (test group). The effectiveness of study was assessed by clinical parameters including Gingival Recession Depth (RD), Clinical Attachment Loss (CAL), Height of Keratinized Tissue (HKT), Gingival Thickness (GT), Percentage of Root Coverage (%RC) at baseline, 1 month and 3 months. Results: A statistically significant reduction in CAL, RD, %RC values ​​was recorded in both groups after a month of surgery. However after 3 months, only statistically significant maintenance was recorded in test group. In test group, the percentage of RC and teeth with complete root coverage were 75% and 62.5%, respectively, higher than in control test, which were 37,5% and 25%. This difference is not statistically significant (p<0.05). Only in the test group, there was a significant increase in GT value (p<0.05) and this result was statistically higher than the control group. Conclusion: At 3 month, CAF+PADM provided similar root coverage to CAF alone, but a significant increase in gingival thickness, reduce the risk of recurrence and loss of keratinized tissue.
