A test composition for evaluating dental caries activity, which comprise a specific amount of a saccharide (e.g. sucrose, glucose and fructose) and a pH indicator (e.g. resazurin, lacmoid, methyl red and alizarin) in water or an aqueous alcohol solution, said composition being regulated to a pH range of 6.5 to 7.0 with an alkali (e.g. sodium hydroxide) and an acid (e.g. acetic acid, tartaric acid or lactic acid). By using this test composition, a test for evaluation dental caries activity can be done within a very short period of time (e.g. about 30 minutes) by any person without requesting any specific training.
