[The effect of local exposure to Mg and heat on the biosynthesis of sulfur-containing compounds in the oral tissues].

: Local Mg electrophoresis was shown to considerably increase the radiolabeled sulphate contents in an application area: gums, mandibular alveolar processes, lower incisors and molars roots. In areas far beyond the phoresis sites (femoral epiphyses and diaphyses) label incorporation was not affected. Mg-free galvanization had no effect on sulphate incorporation into the mineralized tissues. Heating up to 50 C substantially increased the S radioactivity in alveolar processes, molar and incisor roots. Simultaneous heating with Mg electrophoresis produced an additive effect.
