Snyder Test-Relationship between Results of Simplified

S.T. MEDIA in 5-year-old Children and DMFT Increment during a 6-year Period

Abstract

The present study was made to evaluate the possibility of caries prediction by simplified S.T. MEDIA.
A clinical trial of simplified S.T. MEDIA was carried out on 292 kindergarten children aged 5 years. Relationship between the simplified S.T. MEDIA scores and caries prevalence of primary teeth at 5 years of age, and caries incidence on permanent teeth for 5 years were assessed. The subjects were controlled under the school dental health program, which included topical fluoride application during the primary school period. Cohort observations were made for relationship between caries activity test score at 5 years of age and DMFT index from 1982 to 1987, according to the primary school of the subjects.
We investigated the correlation with each test score and deft index and/or deft rate at 5 years of age. A high statistical significance was shown for the relationship between each test score of simplified S.T. MEDIA at 5 years of age and the DMFT index in the 6 th grade.
We recognized a high correlation between the simplified S.T. MEDIA of caries activity test and the clinical findings, and we concluded that the simplified S.T. MEDIA has a high level of caries predictivity.
This test is effective in kindergarten or primary school, because of its simple and easy application.
