The Application of Physicochemical Methods to Studying the Processes of Remineralization of Hard Dental Tissues in Dentistry

摘要

The process of remineralization of hard dental tissues using electrophoresis with a BV preparation that provides the formation of a precipitate of calcium phosphate (brushite) upon the interaction of its components is studied by physicochemical methods including electrochemical impedance spectroscopy and optical and scanning probe microscopy with microanalysis. It is shown in the in vitro experiments that the electrical resistance of a tooth can serve as a criterion of the efficiency of blocking of the dentin canaliculi by the formed precipitate of brushite. The depth of the zone of remineralization is assessed in the case of the treatment with a BV preparation by the method of applications and using electrophoresis. It is found that the latter method possesses a higher efficiency with respect to both the degree of blocking of the canaliculi and depth of penetration into the hard dental tissues. A method of therapy of teeth with the vital pulp is developed based on these studies that shows a high efficiency in the patients from the control group.
