Abstract

Purpose: To evaluate the effectiveness of injectable Platelet-Rich Fibrin (i-PRF) in promoting interdental papilla regeneration in patients with papilla recession. Materials and methods: The study included 38 sites of papilla recession in both the maxilla and mandible. i-PRF was collected using a centrifugation process at 700 rpm with a force of 60G for 3 minutes and was then injected into the papilla using a 1ml syringe with a 30G needle. Each patient received two injections, with the second injection administered 10 days after the first. Clinical periodontal indices and papilla height were recorded at baseline (T0) and 3 months post-treatment (T2). Results: After 3 months of treatment, the height of interdental papilla showed a sighnificant increase, with an initial measurement of 3,0 (2,7 – 3,7) mm at T0, increasing to 3,9 (3,2 – 4,2) mm post-treatment. However, full coverage of the interdental space were not entirely achieved. The plaque index (PlI) decreased from 1,0 (0,0 – 1,0) to 0,0 (0,0 – 0,0) (p < 0,001). No significant differences observed in the outcomes of the GI, PPD, CAL and BOP (p > 0,05). Conclusion: i-PRF injections represent a promising, simple, and rapid method for treating papilla recession, utilizing autologous materials with no risk of allergic reactions. This technique effectively increases papilla height and enhances aesthetic outcomes for patients.
