method for rapid diagnosis of clinical failure of fluoride in tooth enamel

摘要

A method for rapid diagnosis of clinical failure of fluoride in tooth enamel comprising the etching of enamel of 11 or 21 intact teeth with 1 N (3%) hydrochloric acid and determining the intensity of color etched enamel areas with aqueous 1% methylene blue is also performed in dental office in the mouth, which does not require the removal of a tooth and precious equipment; tooth enamel is etched with acid for 10 seconds once, in addition to provoke changes in the permeability of the etched enamel on it for 3-15 minutes to apply 0.15% aqueous solution aminofluoride per fluorine ion to detect the reducing permeability of etched enamel after aminofluoride application on it solution of methylene blue is applied for 10 seconds, the color intensity of the etched enamel areas is assessed twice - after etching of enamel with acid and after aminofluoride application, reducing the intensity of color etched areas in blue color after aminofluoride application indicates the ability to uptake enamel fluoride due to its insufficiency.
