Abstract
In this research Nitrogen laser (N2) was used to induce emission to distinguish between the dental caries and sound teeth.
Three samples of dental caries and one sample of sound teeth has been used to determine absorbance of the dental caries and sound teeth using UV-Vis spectrophotometer then it irradiated by nitrogen laser (N2) with wavelength of 337.8nm, pulse energy 0.04mJ, and pulse time 100msec, interaction between laser and the teeth was happened, teeth absorbed some of these ultraviolet rays induce visible spectrum carried out by a USB spectrophotometer.
The result showed an emission of broad band (363 t0 627nm) and sharp peak (673nm) in the visible region and one sharp peak in the infrared region (1013nm) in all samples, the intensity of this band and peaks is low in dental caries spectra while it was high in the sound tooth spectrum.
