“…Various inorganic based NPs (e. g. Ag, Zn, hydroxyapatite, NCaF 2 , titanium, and copper base NPs) have been shown to increase anti-caries capabilities in dentifrices and mouth-rinsing solutions. Furthermore, metallic NPs found in dental polishing agents and filling materials have been discovered to help prevent caries [ [128] , [129] , [130] , [131] ]. Metallic NPs, alone or in composites, have been shown to exhibit antibacterial and remineralizing capabilities.…”
