The aim of the present study was to describe an safe and convenient method for the
early detection of enamel caries using laser fluorescence. Fluorescence from natually
carious lesion of human teeth illuminated by an argon laser (488 nm) was observed and
photographed using barrier filter. Intact enamel was found to fluorescence with a
yellowish light. Whereas, incipient caries lections in the enamel were clearly visible as
dark areas in contrast to the fluorescence surrounding.
For evaluation of accuracy of this method, lesion depth measured by the laser
fluerescence in light microscope was compared with that polarizing microscope.
The result from the present study can be summarized as follows :
1. Enamel caries of smooth surface was observed as pale white spot and undefined
outline in ordinary light. Whereas, lesion was clearly visible as dark spot in laser
fluorescence.
2. There was no difference between ordinary light view and laser fluorescence in
occlusal surface and interproximal surface.
3. There was no significant difference between the lesion depth observed by laser
fluorescence with light microscope and polarizing microscope.
Apparent correlation exists between two groups.
