ABSTRACT:
A method and device for rapid diagnosis of dental caries are provided in which a very small amount of saliva to be tested is impregnated into a test piece containing a dry reagent. The test piece is supported on a coating film, whereby the test piece can be maintained with the air intercepted to prevent evaporation of saliva for about 15-30 minutes at a temperature around 20.degree.-37.degree. C., and a color change of the reagent due to the enzymatic reaction of the dental caries-causing microorganism is examined.
