APPLICATION OF SCANNING INTERFEROMETRY OF LOW-COHERENCE LIGHT TO MEASURE DEMINERALIZED AREAS OF THE ENAMEL UNDER THE GUM in vivo
Annotation
A low-coherence interferometer of scanning type for tomographic studies in therapeutic dentistry is presented. The features of low-coherence interferometry, which is a unique tool for the determination and analysis of demineralized areas of enamel under the gum in vivo, are considered. It is shown that at a normal incidence of probing radiation at depths from 2000 to 3000 µm, it is possible to measure enamel demineralization with an error of not more than 2.1 µm. The obtained tomograms make it possible to detect in vivo demineralization of enamel under the gum at an early stage of its formation.
