[The dynamics of functional hyperemia in the periodontium].

Time course of functional hyperemia in the periodontium was studied by quantitative rheography in 99 subjects, 55 of these presenting with periodontal diseases and 43 with clinically normal periodontium. Chewing of 5 cm3 of raw carrots for 30 sec on the working side was used as a functional exercise. In normal or reduced tone of regional vessels an oscillatory process of functional hyperemia with a latent period was developing, presumably at the expense of rise of osmotic pressure of tissue fluid.

[Functional hyperemia of the periodontium during the use of chewing gum].

Functional hyperemia developing in the periodontium after 30 sec chewing of a half of a standard chewing gum plate was studied by a noninvasive quantitative method. In subjects with clinically normal periodontium and normal tonic tension of the regional vessels the peak blood flow develops within the first minute of chewing and further vasomotions restore in 30 min. In changed vascular tone, particularly so in periodontal diseases, hyperemia develops persisting for at least 30 min.

[The use of vibrotherapy to prevent suppurative-inflammatory complications in mandibular fractures].

Patients with uni- and bilateral traumatic fractures of the mandible at risk for pyoinflammatory complications were subjected to vibration massage at frequencies identical to those of cardiovascular system. Rheographic evaluation of the blood flow showed vibration-related normalization of the regional circulation at the lesion which went faster and reached the values on the healthy side on day 14. In controls similar improvement took place only in 58% of cases.

[Use of a rheographic technic to detect changes in the regional blood flow in lesions of the facial nerve].

Rheography of the blood flow in the area of the major facial vessels conducted in 50 patients with damage to the facial nerve has shown changes in the regional blood flow in these patients, that are essential for choosing the optimum method of treatment.
