COMPOSITION FOR DYNAMENTAL PAINTING TO ASSESS DENTAL CARE ACTIVITY

摘要

An objective of the present invention is to provide a composition for dyeing dental plaque for evaluation of dental caries activity that is capable of simultaneously dyeing dental plaque and evaluating dental caries activity, and which can evaluate thick dental plaque more accurately than the conventional technique. The composition for dyeing dental plaque for evaluation dental caries activity comprises: a blue pigment being dissolved in water and having a color tone not changing at pH 7 or less; a red pigment being dissolved in water at pH more than 4.5 but not dissolved in water at pH 4.5 or less, and having a color tone not changing at pH 4 .5 or less; and sugar. The content of sugar is preferably 1 to 50 weight parts to the total of 1 weight part of contents of the blue pigment and the red pigment, and ratio of contents of the blue pigment and the red pigment is preferably 1:3 to 3:1.
