Mechanism of differential staining in carious dentin

J Dent Res. 1983 Jun;62(6):713-4. doi: 10.1177/00220345830620060401.

Abstract

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.
