ABSTRACT
Using the information theory, the authors study the relationships between the clinical manifestations of periodontal abnormalities and visceral diseases (diseases of the stomach, liver, kidneys, and the cardiovascular system). Their findings suggest the possibility of detecting visceral abnormalities from clinical signs of periodontal abnormalities.

A total of 737 subjects, divided into 3 age groups, were examined to qualitatively estimate the relationships between gastric diseases and some local factors, on the one hand, and periodontal tissue abnormalities, on the other; maxillary and mandibular periodontium conditions were assessed separately. A contribution of gastric diseases to periodontal condition was revealed, as were combined effects of these diseases and local factors.

A quantitative assessment of the influence of local and general factors on the development of pathologic processes in the periodontium is given for the first time. Factors characterized by the highest influence are distinguished. Mathematical analysis was based on information theory.

A study was made of the effect of swine and bovine calcitrine (CT) on the reparation of irradiated maxillary osseous tissue in 240 rats using histological and histochemical methods. Both types of CT have shown a similar unidirectional effect: the weakening of post-irradiation resorption, the strengthening of osteogenesis, increased preservation of osteogenic cells, and the return of glycosoaminoglycan metabolism to normal. The efficacy of action of swine CT proved to be one order higher as compared to bovine. The authors are of opinion that the most rational dose of swine CT under the conditions of this experiment is 0.2 units/kg to stimulate a quickened method of bone formation. At the onset of treatment an elevation of the hormone dose with its gradual decrease to the optimum one is permissible.
