Abstract: The characteristics of lacquers for surface fluorination Biflyuorid-12, Ftorlak and Ftor-Lux were evaluated in preclinical conditions during this study. During the evaluation of lacquer film retention stability on the surface of artificially damaged enamel the best performance were shown during the study of Ftor-Lux properties. At the presence of lactic acid solution with the pH of 5.5±0.02, at the temperature of 37.0+0.2°C, Biflyuorid-12 lacquer film covered 57.2% of the visual field, Ftorlak and Ftor-Lux lacquers covered 45.5 and 67.1% of the visual field, respectively.
