Evaluation procedures infiltration in the treatment of various forms of dental enamel caries
The article presents the results of electron microscopy of 52 teeth with various enamel caries, that were considered to be infiltrated material «Icon» (DMG, Germany). The investigation has proved, that in case of white carious spots infiltrant occupied almost the entire volume of a pathologic focus (in 81,8 ± 6,71% of cases). However, in case of pigmented spots no infiltration of the lesion to its full depth was observed. In 78,9 ± 9,35% of this group non-infiltrated teeth caries spots were located within the surface layers of dentin. Extrapolating of these results to the clinic, it can be assumed that the infiltration of caries in the primary stage of pigmented spots does not guarantee stabilization of the caries process
