Abstract

|
|
The purpose of this studNr was to develop a practical caries activity test using laser
fluorescence. The subjects of study were 30 children of 7-9 years old. Fluorescence from initial carious lesion of teeth illun mated by an argon laser(488nm) was observed and photographed with barrier filter. For evaluation of accuracy and propriety of this method for cacries activity test, teeth with mitial caries lesion on buccal or labial surface of children was examed with visual inspection and laser fluorescence. Visual examination for the dDfFtT and the CariescreenThl test were also done.
The results from the present study can be summarized as follows:
1. Initial enamel caries of smooth surface was observed as pale white spot and undefined outline under visual inspection with ordinary light. Whereas, lesion was clearly visible as dark spot in laser fluorescence.
2. Laser fluorescence test could differenciate initial caries lesions more effective than visival inspection.
3. There was highest c )rrelation(r=0.73) between laser fluorescent test and CariescreenTTl test. And also apparent correlation(r=0.66) exists between laser fluorescent test and caries experience measured by dDfFtT.
In regard to above results, laser fluorescent test considered to be acurate and reliable method for determining caries activity because of it´s close relationship with caries susceptibility test and caries experience measurements. And it was also considered to be practical beacause it would be simple, inexpensive, and time saving method.
