Abstract

Fluorescence, absorption, and excitation spectroscopy have been widely utilised as probes to collect basic information about physical, chemical, and biological processes. In this study nitrogen laser (N2) was used to induce emission in human teeth to distinguish between dental caries and sound teeth. Three samples of dental caries and one sample of sound teeth have been used to obtain fluorescence spectra illuminated with wavelengths of 337.1 nm, pulse energy 0.04 mJ and pulse time 100 nsec. The absorbance of dental caries and sound teeth was determined using UV-Vis spectrophotometer. The result showed an emission of broadband in the visible region from 363 nm to 627 nm; it provided an amount of information related to intrinsic fluorophores and allowed an accurate diagnosis by the use of the fluorescence intensity changes, it was observed significant decrease of the fluorescence signal intensity related to the carious stage in dental caries, while it was higher in the sound tooth spectrum indicates that the intensity is depending on the amount of decay. A definite diagnosis could be established based on the fluorescence intensity ratio. The future for laser induced fluorescence in diagnostic dentistry has been indicated as accurate and potentially applicable in a wide range in restorative dentistry, periodontology and endodontics.
