Morphological observations by means of scanning electron and optical microscopes as well as microanalytical qualitative and quantitative tests concerning content and distribution of calcium, phosphorus and magnesium in the teeth being in irradiation field were made in patients treated for larynx cancer by method or radiotheraypy. The teeth enamel was in some places thinner and in some others it was lacking. The characteristic defects took place in the form of notches, cracks and of superficial destruction. In X-ray microanalyser the enamel showed some features of demineralization. In dentine, features of demineralization and on the other had features of remineralization were seen. The root dentin, in which destructive processes but also reparation processes developed by root cement could be seen, was rater characteristic. Clear structural changes and disturbances of mineralization in hard too tissues being under therapeutic X-ray irradiation were observed.
