The composition of fluoride varnish has changed over time. Current fluoride varnishes used have the following active ingredients: 5% NaF with a rosin and ethanol. There is also a fluoride varnish containing 7700 µg F/g NH4F in synthetic polymer varnish base and ethanol solvent. Recently, to enhance remineralization, calcium– phosphate compounds were added to some fluoride varnishes. Also, light-curable resin-modified glass ionomer (RMGI) varnishes were introduced into the market. In this study, we compared and analyzed the composition and characteristics of several types of fluoride varnish, differences in fluoride deposition amount as a function of fluorine content and fluorine emission, and the remineralization effects of fluoride varnishes that contain substances to promote remineralization. Additionally, we provide information that can be helpful when choosing fluoride varnish in clinical practice.
