Abstract

The investigation was performed on extracted teeth which were in wet and dry condition. Firstly the intensity of HeNe-laser light backscattered on enamel facial surface was measured. Then plano-parallel longitudinal facio-lingual slice has been made from each tooth. The spatial distribution of side- scattered HeNe-laser radiation has been detected by CCD camera while the laser beam was aimed on to enamel surface (formed facet) of slice. The obtained data demonstrated the dependence between backscattered intensity, distribution of light scattered inside dental tissues and tissue status. The last one included the degree of enamel maturation and demineralization, degree of enamel hydration, enamel thickness, existence of sclerosed dentin.
