Abstract
The condition of the enamel surface is extremely crucial to the restoration of the primary enamel lesion. We investigated the methods used to observe and measure the precise de-/remineralization reaction on an experimental enamel subsurface lesion. The following conclusions can be drawn on the basis of the results of the present study :1.To quantitatively and visually evaluate the enamel surface, histopathological examination using polarized light photomicrographs and microradiographs is effective.2.The effect of remineralization and demineralization inhibition can be confirmed by quantitatively measuring the reaction area depth and mineral loss.3.Regardless of the treatment conditions, the reaction area depth increases during pH cycling.It takes longer time for the remineralization than that for the demineralization. White spots on the enamel surface are an indication that the surface is extremely susceptible to mechanical irritation. The balance between demineralization and remineralization is crucial for the prevention of caries. To attain this balance, in addition to enhancing remineralization, demineralization should be inhibited, via lifestyle changes.
