“…It can be used as a standalone material to trigger certain cellular functions, a 3D gel scaffold for cells growth and differentiation, gel scaffold working as a physical barrier between soft and hard tissue, gel scaffold containing growth factors or other natural factors (bone morphogenic factors, fibroblast growth factors, platelet-derived growth factors) released over certain time and/or concentrations, carrier for drugs ensuring their sustained release, and co-material with other biological (fibrin, collagen, chondroitin sulphate, hydroxy apatite), natural (cellulose, chitin, starch, alginate, silk), or synthetic materials for enhanced function of either entity. HA applications in dental procedures vary widely, and one should always keep in mind the four essential factors (cell viability, type of cellular trigger, angiogenesis, physicochemical characteristics of the scaffold) required for regeneration or wound healing as evaluation tools when exploring the possible applications or expected outcome results of a natural biomaterial [30,36]. Some examples on HA uses in dentistry include:…”
