We have developed a rapid caries activity test (Resazurin Disc test, RD test) based on the specific color reaction of resazurin. In a previous paper (1984), we investigated the relationship between the RD test scores and caries prevalence for a clinical trial. In this report, the possibility of caries prediction by the RD test score was studied. A clinical trial was carried out on 33 kindergarden children aged 4 years.<BR>Relationship between the RD test scores and caries increment on initially sound surfaces after 6 and 12 months (Δdf-s) was assessed. Caries increment (Δdf-s) in the high score group (_??_·_??_) was greater than in the low score group (-·+). This tendency was more notable after 12 months.<BR>We also recognized the necessity of taking into account the age of the subjects, the type of teeth, and the specific tooth surfaces in the case of estimation of caries prediction.
