As an object of study extracted human teeth were used. The whole was explored 30 teeth; measurements were conducted in intact regions of tooth: enamel, dentine, cement, root canal and in pathologically changed areas: caries of teeth and a solid teeth plaque. From present fluorescent spectrums of intact: enamel, dentine, cement; and of pathological: caries and teeth stone is seen that curves are likely shaped for each of the groups, but their amplitudes are not the same. Fluorescence maximum of all tooth areas falls on 700 nm, herewith possible to say that, spectrum shapes are specific for each tooth area, that can be used in diagnostic purposes, for example when processing a carious cavity. As to florescence intensity that teeth stone possesses the maximum of fluorescence, then an area submitted to caries, intact areas possess a weak fluorescence. |
