Fluorine content in natural cow milk has been determined with a view to the fluoration of the milk and its use for dental caries prophylaxis. Fluorine has been determined by the method of standard calibration, making use of fluorine selective electrode and "Orion SA 720 pH/ISE Meter" with LCD display. The mean fluorine quantity in milk is mean = 0.046 ppm, being far lower than the optimal fluorine concentration.
The protective properties of varnish films of dentin adhesit and cyanacrylate B-10 versus the toxic action of the compositional material have been studied in experiments on dogs. For that purpose, 45 cavities, class V with size 2:4; 1.5 mm were made. Dentin was isolated by a film from the experimental materials. The control group of teeth were made inlays from phosphate cement. The histopathological reaction of the dental pulp to the materials on trial was determined on day 3, and 1 and 3 months of the beginning of the experiment. No changes, characteristic for acute or chronic inflammatory reaction were established. The good, both immediate and late, results from the experiment are a good reason to admit that the adhesives obtained are suitable for varnish isolation of dental defects with superficial and moderate depth and could be applied with success in the clinical practice under the compositional material. They have no effect on the final aesthetic effect of the obturations.
The intensive development of medical informatics and cybernetics led to the creating of an impressive mathematical apparatus, associated with algorithmization of medical activities and processes. In that aspect, special attention is paid to the nozometric algorithms, applied in the most responsible medical field--therapeutic-diagnostic process. The existing nozometric algorithms are reviewed, with consideration given to the specificity of the stomatological diagnostics. An algorithm set has been systematized that is recommended for use in the field of stomatology.
The purpose of the authors with the present study was to obtain data on the information of the pregnant women about problems associated with the stomatological health. Anonymous inquiry was carried out among 250 pregnant women from the town of Sumen and the region. The questionnaire has 7 questions. The answers give information on the knowledge about problems associated with nutrition, fluorine prophylaxis, formation of dental germs and cutting. The results reveal insufficient knowledge in all problems. Conclusions are drawn that the micro-courses during the last months of pregnancy in stomatological prophylaxis are ineffective. The individual work proved to be insufficient as well as the participation of the regional and workshop stomatologists.
Thirty two children, aged from 6 to 14 were studied by the rheoencephalographic method during general halothane and laughing gas anesthesia, stomatologically treated under out-patient department conditions. The quantitative analysis of the rheoencephalographic curves made of the method of differentia, the data being compared one hour before the general anesthesia, during the stage of surgical anesthesia and one hour after it. Statistically significant data were established showing pulse supply improvement and reduction of vascular tone of the brain blood vessels during general anesthesia and one hour after it. The expedience of the application of the rheoencephalographic method during general anesthesia is stressed upon as well as the potentialities of its application in the stomatological practice. The positive qualities of the method of general anesthesia applied for the stomatological treatment of children under out-patient department conditions are confirmed.
