What concentration of sodium hyaluronate can be used to fill teeth?
0.3- 1% sodium hyaluronate can be used for filling. According to relevant public information, sodium hyaluronate, also known as sodium hyaluronate, is a natural macromolecular linear mucopolysaccharide formed by repeatedly connecting D- glucuronic acid and N- acetylglucosamine as disaccharide units, which widely exists in animal tissues and body fluids, such as joint fluid, vitreous body, umbilical cord and skin. Sodium hyaluronate has good viscoelasticity and excellent water retention because of its unique structure, and has important physiological and biological functions, good histocompatibility and no immunogenicity, so it is widely used in clinic. Sodium hyaluronate can protect eye tissue when used in ophthalmic surgery.
