Clinical Evaluation of Hyaluronic Acid and Platelet Rich Fibrin Injection Efficacy in Interdental Papilla Reconstruction

The goal of this clinical trial is to evaluate and compare the efficacy of injectable platelet rich fibrin (i-PRF) and hyaluronic acid (HA) in reconstruction of interdental papilla loss. The main questions it aims to answer are: * How compareable are above mentioned two interventions (i-PRF\&HA) in reconstruction of interdental papilla loss? * Which treatment option is better accepted by patients? Which treatment option would patients be more satisfied with? Participants with multiple interdental papilla loss will be treated with both i-PRF and HA in split-mouth design. Researchers will compare two treatment options to see if black triangles caused by interdental papilla loss closes and if yes, for how long do they last.
