摘要
Fluorine is present in the hydroxyapatite mineral in natural tooth enamel,which plays a key role in the prevention of dental caries.The aim of this study is to synthetize the fluorinated urchin-like serried hydroxyapatite(FnUHA)particles with different degrees of fluorine substitution and explore the effect of the fluorine element on the water absorption-solubility,mechanical strength,and biological activity of dental composites.
