The purpose of this study was to evaluate the diagnostic validity of an incipient occiusal caries using argon laser fluorescence.
Extracted human premolars and molars with enamel carious lesion of occlusal surface were assessed using visual examination, visual examination with probing, argon laser fluorescence and histologic depth of carious lesion.
The results in each of all the three detection methods were compared to the assessment of histologic depth of carious lesion using polarized microscope.
The results from the present study can be summarized as follows:
1. There was highly correlation between the histologic depth of occlusal caries and all three detection methods(P ( 0.01).
2. The reproducibility(kappa value) of the visual examination, visual examination with probing and argon
laser fluorescence between the histologic depth of occiusal caries was 0.189, 0.128, 0.472.
The highest correlation was seen between detection of occlusal caries by argon laser fluorescence and histologic scores by polarized microscope.
The results from this study indicated that argon laser fluorescence considered to be accurate and reliable method in detecting occlusal caries.
