title: A follow-up study on three caries activity tests.
abstract: The purpose of this research was to study the efficacy of three CAT's (Dentocult SM, Dentocult LB and Dentobuff Strip) in revealing caries condition and predicting caries progress, and provide a reference for application by comparing the three tests. Oral condition and results of the three CAT's of 82 children aged 3 to 4 were recorded and followed up. The examination was checked again two years later. The caries incidence, dft and CSI data from the two examinations were analyzed statistically. The results were that each Dentocult SM degree showed significant variances in incidence rate, as did the dft and CSI results in the second examination. The dft and CSI of both examinations exhibited a high degree of statistical significance. The same may be said of the Dentocult LB findings for the two years. No noticeable variances in caries incidence rate, dft and CSI from the Dentobuff Strip test were observed in both years' study, nor was there any statistical significance drawn from the findings, except for those of the second exam. No gender differences were observed in the distribution by degree with the three CATs The conclusion is that Dentocult SM is the best of the three tests for the diagnosis of the presence of caries and prognosis of its progress, Dentocult LB is second best whereas the Dentobuff Strip shows no detection capability. The findings serve as an application reference.
