(searched for: Comparative Clinical Evaluation of Platelet Rich Fibrin and Subepithelial Connective Tissue Graft in Interdental Papilla Reconstruction: A Randomized Controlled Clinical Trial)
European Journal of Dental and Oral Health, Volume 2, pp 7-12; https://doi.org/10.24018/ejdent.2021.2.5.90
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.

Background: Platelet-rich fibrin (PRF) has emerged as one of the promising regenerative materials in the field of periodontics. Hence, this study evaluated the efficacy of subepithelial connective tissue graft (SCTG) and PRF in surgical reconstruction of interdental papillae using Han and Takei technique. Materials and Methods: A total of 20 sites with Class I and Class II interdental papilla defects were assigned to two groups (Group 1 – Han and Takie technique + SCTG and Group 2 – Han and Takie technique + PRF). Parameters such as papillary height (PH), distance from the contact point to the tip of papillae (CPTP), papilla presence index (PPI), pocket probing depth (PPD), relative clinical attachment level (RCAL), plaque index (PI), gingival index (GI), and distance from contact point to alveolar crest (CP-BC) were measured at baseline and after 3 months. The significance of difference within and between the groups was evaluated with paired and unpaired t-tests. Results: The mean PI, GI, PPD, RCAL, PPI, and CPTP distance decreased significantly, whereas the mean PH increased significantly in Group 1 as well as in Group 2. After 3 months, mean reduction in CPTP distance and mean gain in PH were statistically significant in Group 1 as compared to Group 2. However, there was no significant difference in mean CPBC distance between baseline and 3 months in Group 1 as well as in Group 2. Conclusion: Both the techniques were effective in the treatment of papillary recession defects; however, more significant clinical papillary enhancement was achieved after the surgical reconstruction with SCTG.
