title: Morphology and microanalysis of teeth in scleroderma.
abstract: The studies were carried out on teeth extracted for stomatological reasons in the persons with generalized scleroderma. The studies included: morphologic examination of the longitudinal and cross-ground sections in the light and scanning microscope, and microanalytic examination of the longitudinal halves of the teeth in the X-ray microprobe. In the course of scleroderma morphological changes of the mesenchymal origin occurred in the teeth hard tissues. The deviation in the calcium and phosphorus contents was relatively significant and an absence of magnesium in the dentine and distinct dećrease in the calcium-phosphorus ratio were observed.
