Objective: This study aimed to clinically evaluate the efficacy of coronally repositioned flap in the treatment of isolated Miller’s class I and II gingival recession. Materials and Methods: Twelve patients with Miller’s class I and class II recession were selected. Patients were randomly divided into two groups: Group A (control group): coronally repositioned flap and Group B (test group): coronally repositioned flap with bioabsorbable collagen membrane. Clinical evaluation parameters such as probing depth (PD), clinical attachment level (CAL), width of keratinized tissue (WKT), gingival biotype (thickness), recession width (RW), and recession depth (RD) were recorded at baseline and at 1, 3, and 6 months post-operatively using an acrylic stent. Results: A significant gain in CAL (−0.6, −0.78, and −0.60 mm) and WKT (0.25, 0.48, and 0.83 mm) was observed in both the groups from baseline to 1, 3, and 6 months, respectively. However, the gain was more in the test group than the control group. Similarly, a significant decrease in mean RD and RW was more in the test group when compared with the control group (significant P-value <0.001) 6 months post-operatively. Also, no statistically significant change was found in the two groups in terms of PD and gingival tissue at 6 months. Conclusion: The results of this study suggest that collagen can improve the clinical outcomes of the coronally repositioned flap operation in the therapy of localized recession defects.
