[Determination of caries activity levels in children aged 4-6 years by the modified Snyder test]

Modified Snyder Test, which is a good instrument in motivating the patient and determining the effectiveness of preventive programs, is used commonly in Public Health Research programs for measuring the the caries activity levels. In our study, by using modified Snyder Test instead of Snyder Test, which is more preferable because of its' simplicity in application, we determined the caries activity levels of the children, aged between 4-6 years, which remained as an unexamined group in our population up to date. In our study, consisting of fifty children, caries rate was found to be 36% depending on WHO's criteria, while caries percentile for each tooth was 5.8% and df index was 1.18. According to the modified Snyder Test results, 46% of the children had positive results at the end of the 48 hours, which indicates a mild caries activity degree. This result is also in accordance with the caries of the group.
