Abstract
This study aims to analyze (1) the presence of elements (SEM-EDS) on the surface of human enamel treated with fluoride varnishes and (2) the formation of CaF2 on the human enamel surface after the application of TiF4 and NaF varnishes in vitro. Human enamel samples (sound and previously demineralized in vitro) will be treated with different concentrations of TiF4 and NaF varnishes for sub…
