The caries detector, 1.0% acid red solution in propylene glycol, failed to stain EDTA-demineralized bovine dentin matrix, but stained the same matrix when treated by lactic acid in a concentration above 0.01 M. Thus, acid of bacterial origin could possibly be responsible for the stainability change of carious dentin in vivo.
龋蚀检测仪，即丙二醇中的1.0%酸性红溶液，未能使经乙二胺四乙酸（EDTA）脱矿的牛牙本质基质染色，但当用浓度高于0.01 M的乳酸处理时，该基质会被染色。因此，源自细菌的酸可能是导致体内龋损牙本质染色性变化的原因。
