Comparative evaluation of injectable-platelet rich fibrin and hyaluronic acid injections in the treatment of gingival black triangles.

Introduction : Gingival black triangles are cosmetic deformities which occur due to loss or absence of interdental papilla, so reconstruction of interdental papilla have always been a challenging task in esthetic dentistry. This study aims to compare injectable platelet rich brin and hyaluronic acid injections in the treatment of gingival black triangles. Material and Methods : 40 sites were divided into two groups ; Group A and Group B. In Group A, Injectable platelet rich brin was deposited whereas in Group B hyaluronic acid injections were deposited. All the sites were examined for gingival index, plaque index, Papillae presence index and Black triangle area at baseline, 1 month and 3 months follow up. Results : On statistical analysis of the recorded data, results revealed statistical signicant difference in both the groups in Papillae presence index and Black triangle area from baseline to 1 month and 3 months follow up. Conclusion : Injectable Platelet rich brin can be a viable alternative to hyaluronic acid injections in the treatment of gingival black triangles.
