Abstract
Compositions capable of evaluating dental caries activity by making use of color reaction, which are composed of an aqueous solution containing coloring agents and water-soluble substances that are to produce an osmotic pressure higher than the physiological one on the cell membrane of cariogenic bacteria but free from any buffer action by themselves. Upon introducing dental plaque of a dental caries patient into this solution and thus measuring activity of the sordes by means of color reaction, it is possible to evaluate readily the status praesens of dental caries and its activity without any cultivation of cariogenic bacteria being required.
