Abstract
The purpose of this study was to investigate the application of UV laser spectroscopy for detecting the early dental caries lesion. Fifty human bicuspids and molars were collected, cleaned, and divided into sound teeth, incipient caries teeth and advanced caries teeth groups. All the samples were cut into halves from occlusal to root apex. Sound teeth samples were polished and demineralized at decalcifyng solution(pH 4.0) for 0, 30, 60, 120 and 240 minutes. Characteristics of laser fluorescence among sound, incipient and advanced -caries, and among demineralized teeth groups were measured using the Optical Multichannel Analyzer(OMA), Scanning Electron microscope(SEM) and Confocal Laser Scanning Microscope(CLSM). The obtained results were as follows:
1. The linear decrease of the peak ratio values in the artificial demineralization for 0 to 2 hours seems can be applied to the diagnosis of the caries from the suspected lesion.
2. Since the peak ratio decreased as the remineralization increased, any subtle change in the tooth can be detected by comparing both sound and suspected, incipient, lesion even though the morphological change in this stage cannot be identified. In this in vitro study, the morphological change after the demineralization process was merely observed in the nanometer range.
3. Comparison of the peak ratio between the sound and artificially induced lesion has shown effectiveness on the determination of the surface change due to the demineralization.
4. Form the results, the UV-laser spectrum induced by 325 nm laser beam is believed to useful for the diagnosis of incipient dental caries.
