专利汇可以提供Detecting liquid for caries part of tooth专利检索，专利查询，专利分析的服务。并且PURPOSE: To make it possible to dye the caries dentin of a tooth and a sound dentin separately, by using dimethyl sulfoxide as an organic solvent.
CONSTITUTION: Acid red is dissolved in dimethyl sulfoxide or the mixed liquid of said material and water as a coloring matter. The acid red is the potassium salt of 9-(3W6-tetrachloro-ortho-carboxyphenyl)-6-hydroxy-2,4,5,7-tetrabrom-3- isoxanthone. An organic acid which is used as a detecting liquid is carboxylic acid, ascorbic acid or a mixed material of these acids. It is desirable that the concentration of the acid red in the detecting liquid is 0.1W0.5wt.%. When the mixed liquid of the dimethyl sulfoxide and water is used as the solvent, the concentration of the dimethyl sulfoxide based on the mixed liquid can be 5wt.% or more. As the ratio of the organic acid, 60wt.% or less based on the dimethyl sulfoxide or the mixed liquid of the methyl sulfoxide and the water is enough.
