Hyaluronic acid: a promising biomaterial in periodontal regeneration and wound healing

Hyaluronic acid has been widely used in different regenerative medical procedures due to its widespread presence in connective tissue. While its use in various fields of medicine has proved its efficacy in terms of regeneration and wound healing, in dentistry hyaluronic acid has been introduced recently. The molecule has suitable physiochemical characteristics and pleiotropic biological effects. The application in clinical practice can offer additional benefits, stimulating bone and soft tissue regeneration.


The lecture will provide an overview of the specific characteristics of hyaluronic acid as a promising and affordable biomaterial. Applications in non-surgical procedures including papillae augmentation, mouth ulcers treatment, socket preservation, gingivitis and conservative periodontal treatment, as well as surgical treatment, bone grafting and regeneration is discussed. Clinical cases, indications, and recommendations for utilizing hyaluronic acid are also provided.
