System for optimized formation of fluorapatite in teeth |
| abstract |
The invention consists of a system comprising a measuring device of shape adapted to the tooth, which with yellow, green and blue colour grades the current pH value in the patient's tooth film and in which the green colour indicates the optimum pH value for the formation of caries-counteracting fluorapatite. Three types of colour-matching tubes of toothpaste have compositions that contain fluoride and centre the pH values of the tooth films on the green level. The system's measuring device shows by colorimetric means which toothpaste will at that precise time best promote the formation of fluorapatite in each of the three pH groups from which the device selects. |
