Comparative Clinical Evaluation of Hyaluronic Acid and Medpark Fill Collagen in the Management of Interdental Papillary Deficiency

Purpose: Interdental papillary deficiency, commonly presenting as “black triangles,” is a major esthetic concern in periodontal practice. Minimally invasive approaches such as injectable biomaterials have gained increasing popularity as alternatives to surgical reconstruction. To compare the clinical efficacy of hyaluronic acid and Medpark Fill collagen in the management of interdental papillary deficiency and to evaluate their impact on periodontal esthetics. Materials and Methods: A prospective clinical trial was conducted on 30 patients with Class I and II papillary recession (Nordland and Tarnow classification). Patients were divided into two groups: Group A (hyaluronic acid) and Group B (Medpark Fill collagen). Clinical parameters including black triangle height, pain (VAS), and patient satisfaction were assessed at baseline, 3 weeks, 6 weeks, and 3 months. Results: Both groups showed a statistically significant reduction in black triangle height over time (p<0.001). However, intergroup comparison revealed no statistically significant difference (p>0.05). Pain scores decreased significantly in both groups, and patient satisfaction levels were comparable. Conclusion: Both hyaluronic acid and Medpark Fill collagen are effective, minimally invasive options for papilla augmentation with comparable clinical outcomes.
