The purpose of the study was to evaluate the effect of fluoride ion released from an experimental fluoride-releasing elasromer (rubber) on the subsurface demineralization of human enamel in vitro by digital microscopy and microdensitometry. The sheet-shaped fluoride-releasing rubber with 0.5wt% SnF_2 was set on an enamel block. The fluoride-releasing test was processed in de-ionized water for 2 weeks. The enamel, which absorbed the fluoride from the elastomer, together with the adjacent enamel (control), which was not affected by the fluoride, was demineralized in an acid lactic buffer solution (pH4.5) for 3 days. The ultra-structure of the subsurface demineralization was observed with an advanced digital microscope, while the mineral loss (ΔZ) and lesion depth (Ld) were measured by microdensitometry. It was qualitatively and quantitatively showed that the mineral loss and lesion depth were significantly different between the enamels affected by the fluoride ion and controls (p<0.01). It was suggested that the digital microscopy and microdensitometry were useful methods to evaluate the effects of fluoride ion on the subsurface demineralization of enamel.
