COMPARATIVE EVALUATION OF MODIFIED TRIANGULAR CORONALLY ADVANCED FLAP IN COMBINATION WITH PLATELET RICH FIBRIN OR TYPE I COLLAGEN MEMBRANE FOR TREATMENT OF MILLERS CLASS I AND CLASS II GINGIVAL RECESSION

Background: The study aimed to clinically evaluate the outcome of modified triangular coronally advanced flap (mtCAF) alone or in combination with platelet rich fibrin or type I collagen membrane in the treatment of Millers Class I and Class II gingival recession. Methods: 45 sites with Millers Class I or II gingival recession were recruited and allocated into 3 groups with 15 sites each. Group 1: mtCAF alone, Group II: mtCAF with PRF and Group III: mtCAF with bioresorbable collagen membrane (Bio-Gide®). Standardized Clinical Parameters such as Plaque Index (PI), Gingival Index (GI), Pocket Probing Depth (PPD), Clinical attachment level (CAL), Gingival Recession Depth (GRD) and Keratinized Tissue Height (KTH) were measured at baseline and 6 months. Result: All the three groups showed improvement in clinical parameters but it was not statistically significant. However, a significant increase in keratinized tissue height was seen in Group III as compared to Group I and Group II. Conclusion Modified triangular coronally advanced flap (mtCAF) alone or in combination with PRF and collagen membrane showed good clinical outcomes but better results were obtained in terms of keratinized tissue when collagen membrane was used.
