In vitro study of the preventive activity of fluoride varnish by X-ray diffraction

In exogenous prophylaxis, fluoride is applied directly to the tooth surface through various gels, varnishes, foams, and toothpaste. According global burden of disease study conducted in 2017, more than 530 million children worldwide suffer from dental caries their primary dentition. There are few developments selection non-invasive methods application mineralizing varnishes. The researchers investigated experimentally, in-vitro preventive activity varnish Clinpro™ White Varnish with TCP 3M (CV), using a modern method X-ray diffraction. 20 temporary teeth were extracted due physiological changes. Place was UMDC - city Varna Institute Physical Chemistry "Academician Rostislav Kaishev" Bulgarian Academy Sciences, Sofia. Demineralization carried out 37% phosphoric acid (i-gel – etching gel) smooth enamel surfaces for 30 seconds. models then washed dried water air jet. Remineralization performed CV. formation small globules calcium fluoride. coating composed mainly fluorapatite. With diffraction, it proved that prophylaxis remineralization therapy effective prevention treatment initial lesions.
