Abstract. The possibilities of using an automated coherent-limited interferometric system for tomographic measurements in dentistry are considered. Results of experimental studies in vivo of mineralized deposits under the gum in the area of the maxillary and mandibular arches of the first and second molars are presented. Dependence of the reflection coefficient distribution on the depth of the gums in the absence of mineralized sediment and in its presence is analyzed. The results of measurements of the geometric parameters of mineralized deposits are shown to have an error less than 1 µm. A scheme of the automated coherent-limited interferometric system and its technical characteristics are presented.
Keywords: interferometric system, tomography, mineralized sediments, molar, reflection coefficient, measurement error, measurement range
