ABSTRACT
The purpose of this study was to develop a practical caries activity test using laser fluorescence. The subjects of study were 30 children of 7~10 years old. Fluorescence from initial carious lesion of teeth illuminated by an argon laser(488nm) was observed through barrier alter. For evaluation of accuracy and propriety of this method fer caries activity test, teeth with initial caries lesion on buccal or labial surface of children was examined with visual inspection and laser fluorescence. Visual examination for the dDfFtT and the Cariescreen® test were also done. The results from the present study can be summarized as follows: 1. Laser fluorescence test could differentiate initial caries lesions more easily than visiual inspection. 3. There was highest correlation(= 0.73) between laser fluorescent test and Cariescreen® test and. And also apparent correlation(= 0.66) exists between laser fluorescent test and caries experience measured by dDfFtT.
Keywords: Argon laser | Caries activity test | Laser fluorescence | Initial caries lesion
