Influence of a polymeric infiltrant on the density of enamel white spot lesions

In modern dental practice, treatment of early stages of caries is possible using minimally invasive intervention. In this work, using X-ray computed microtomography (micro-CT), an ex vivo non-destructive study of the density of white spot lesions was carried out before and after the application of a polymer infiltrant. The use of a calibration phantom during microtomography of samples, as well as the technique of segmenting regions of interest on caries foci after reconstruction of microtomograms of teeth, made it possible to study the quantitative effect of the infiltrant on pathologically altered enamel.
