소아에서 치아 우식 경험과 새로운 치아 우식 활성 비색 검사

Abstract

A new colorimetric test (Cariview®) using a new type of pH indicator can reflect the acidogenic potential of plaque bacteria. The objective of this study was to evaluate the correlation between Cariview® and the caries experience (measured through the dmft index) of children, and to compare Cariview® with Dentocult SM®. Having obtained informed consent, 135 children less than 6 years old participated in the study. We examined their dmft index, and performed two caries activity tests (Cariview® and Dentocult SM®) according to the manufacturers’instructions. In the results, Cariview® showed a moderate correlation with the dmft index (r = 0.43, p < 0.01). Cariview® showed a sensitivity of 68.8%, a specificity of 69.2%, and an area under curve of 0.686 in the ROC curve analysis. Cariview® had a significant correlation with the children’s caries experience and had a slightly better explanatory ability than Dentocult SM®. Furthermore, Cariview® was convenient and easy to use on uncooperative children, and also had an educational effect with its visual colors. It is suggested that Cariview® could be used clinically to identify the children susceptible to develop caries and to establish a preventive strategy.
