Comparative evaluation of efficacy of subepithelial connective tissue graft versus platelet-rich fibrin membrane in surgical reconstruction of interdental papillae using Han and Takie technique: A randomized controlled clinical trial.

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 -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.
