Abstract
Aim: The purpose of this study was to evaluate the preventive effect of nanosilver fluoride (NSF) on intact enamel surface by using energy dispersive x-ray spectroscopy (EDX-analysis) to detect the superficial fluoride precipitation on the surface of intact human dental enamel.
Methodology: In this study, we used energy-dispersive X-ray spectroscopy (EDX) to detect the precipitation of fluoride on the surface of flat polished enamel surface after NSF application.
Results: Our data has shown that treatment with NSF for 2 minutes led to significant precipitation of fluoride on enamel surface as compared to untreated samples. The precipitated fluoride was detected 7 days after the varnish application.
Conclusion: Nanosilver fluoride varnish application on the surface of sound unaffected enamel can be an effective caries preventive measure. Fluoride precipitation on the surface of enamel and its further incorporation in the crystal lattice will lead to the formation of less soluble fluorapatite crystals that are more resistant to the cariogenic bacterial demineralizing acids.
