Application of Chitosan Biomaterials in Dentistry—A Narrative Review

Abstract Chitosan is a versatile natural biomaterial that has been researched for a range of bio-dental applications. It possesses various desirable qualities such as biocompatibility, hydrophilicity, biodegradability, and a broad antibacterial range (covering Gram-negative and Gram-positive bacteria as well as fungi). Moreover, the molecular structure contains reactive functional groups, which provide numerous reaction sites and possibilities for the formation of electrochemical interactions at the cellular and molecular levels. Chitosan's unique features have attracted material scientists from all over the world to explore its applications in dentistry. The objective of this review is to highlight the creation of new chitosan biomaterials and as to how it is a vital component for the improvement and modification of existing dental materials being used.
