Comparative Clinical Evaluation of Platelet Rich Fibrin and Subepithelial Connective Tissue Graft in Interdental Papilla Reconstruction: A Randomized Controlled Clinical Trial

Background: Aesthetics has become a major concern nowadays. Loss of interdental papilla in the anterior region of the oral cavity accounts for a major compromise in aesthetics. Thus, techniques to correct this defect has emerged as a new area of research in dentistry. The present study aims to compare reconstruction of the interdental papilla using subepithelial connective tissue graft (SCTG)and platelet rich fibrin (PRF). Material and Methods: The present randomised clinical trial included 36 patients equally divided into test (platelet rich fibrin) and control groups (subepithelial connective tissue graft). Papilla reconstruction was done and clinical parameters- contact point to interdental papilla distance (CPID), width of keratinized gingiva (WKG), plaque index (PI), gingival index (GI), papillary bleeding index (PBI), pocket depth (PPD) were recorded at baseline, 3 and 6 months. Healing index (HI) was recorded at 1, 2 and 3 weeks. Results: At the end of 6 months, it was found that interdental papillae fill in terms of decrease in distance from the contact point to the interdental papilla tip and gain in WKG was statistically significant in both the groups (p value ≤0.05). On intergroup comparison, however, it was found that the improvement in the abovementioned parameters was significantly greater in the control group (39.32%) as compared to the test group (14.79%). The difference in other clinical parameters at various time intervals were found to be nonsignificant.
