''Efficacy of Locally Delivered Hyaluronic Acid Gel as an Adjunctive to Non-Surgical Management of Periodontitis

Hyaluronic Acid (HA) is an addition to the local chemotherapeutic agents. Hyaluronic acid was discovered by Meyer and Palmer. HA is widely found in the extracellular matrix and it plays an essential role in controlling cell behavior including random motility, metabolic reactions, chemotaxis, proliferation and invasion. HA is released by many cells including fibroblasts

NSPT, with or without adjunctive therapies, is an effective treatment for periodontitis. It reduces PD and results in formation of some new attachment; however, it also has several limitations, and surgical therapy might be required to control inflammation and optimize outcomes. When used for non-surgical scaling and root planing, periodontal curettes can reach a mean PD of up to approximately 5.5 mm. The mean PD in which a plaque-free and calculus-free surface can be established is \<4 mm
