The purpose of this study was to evaluate the diagnostic validity of early proximal caries lesions using laser fluorescence and whether the detection could be enhanced using a fluorescent dye. Direct visual examination and bitewing radiograph were used for comparison.
The subjects of this study were 30 children of 3-9 years old. Laser fluorescence and dye-enhanced laser fluo¡þrescence(mixed wavelength of 488 and 514 nm) were used and viewed through glasses (excluding wavelength ( 520 nm). For dye-enhanced laser fluorescence a 0.075% sodium fluorescein dye was applied before examina¡þtion. Proximal caries lesion of each subject was assessed using visual examination, bitewing radiograph, laser fluorescence, and dye-enhanced laser fluorescence.
The results in the three detection methods were compared to the assessment of bitewing radiograph. The results from the present study can be summarized as follows:
1. There was highly correlation(r=0.725-0.911) between the bitewing radiograph and all three detection methods(p(0.05)
2. The reproducibility(kappa value) of the visual examination, laser fluorescence and dye-enhanced laser fluorescence comparing with bitewing radiograph of proximal caries was 0.451, 0.683, 0.772, respectively.
There was highest correlation between dye-enhanced laser fluorescence and bitewing radiograph for detection of proximal caries. The results from this study indicated that the dye-enhanced laser fluorescence considered to be accurate and reliable method in detecting proximal caries.
