[Physicochemical research on the bone tissue of the alveolar process in experimental periodontitis].
The thermal behavior of inorganic and organic components of the osseous tissue of the mandible alveolar process from experimental animals was first examined in health, elementary periodontitis and during its magnetic laser therapy. The derivatograms of the diseased osseous tissue were characterized by shifted maximum of the thermal effects observed towards the high temperature region and new peaks at 390 and 500 degrees C, which showed that highly boiling polypeptide fractions resistant to oxidation were prevalent in the organic matrix of osseous tissue. The abnormal process in the osseous tissue was largely explained by the conformational rearrangement of protein molecules, which in turn causing changes in their functional properties associated with formation of insoluble inorganic phosphate of routine composition and structure. As a result of magnetic laser therapy, thermic transformations in the examined samples followed the scheme that was close to thermal analysis of intact osseous tissue.
