[Dynamic method for measuring the periodontal area].

The study was carried out on 21 teeth before and after their removal in 9 patients. Mechanical parameters of the dental supporting-retaining system were studied with a two-parametrical periodontometer, which evaluates the tooth mobility and angle of losses, characterizing the internal friction in the tooth-periodontium-bone system. The in vitro area of the periodontium was evaluated using millimeter paper. A direct relationship between the angle of losses and periodontal area was revealed. The authors suggest using a coefficient of propotionateness between the periodontal area and angle of losses; this coefficient does not depend on the tooth mobility and periodontal area.

[Results of measuring tooth mobility by a two-parameter periodontometer].

A new method for evaluating mobility of a tooth and area of its periodontium is suggested. The evaluation of elastic and viscous components of tooth mobility is based on theoretical estimations. Clinical evaluations of tooth mobility were carried out in patients with physiologically normal periodontium making use of a two-parametrical periodontometer. Experiments demonstrated that the ratio of elastic to viscous components of the tooth mobility is proportionate to periodontal area. Two-parameter periodontometer gives data on complete mobility of a tooth and periodontal area.

[Vitamin C and B1 allowance in various diseases of the gastrointestinal tract].

In 92 patients with various chronic affections of the gastro-intestinal tract vitamins C and B1 content in the blood and urine was measured. As controls 17 healthy persons were examined. Patients with gastro-intestinal affections were found to show a statistically significant fall of the vitamins C and B1 level in the blood and urine at all seasons of the year (winter, spring, summer and fall). But their decline is most intensive with exacerbation of the ailment and then the presence of the pain syndrome is attended by a steeper drop in the level of these vitamins. A course-wise parenteral administration of the vitamins C and B1 results in their statistically significant rise in the blood and urine, their level, however, remaining below that in healthy persons.
