[Dental occlusion and pathology of periodontal inflammation].

Effect of occlusion disorders on regional circulation in periodontal tissues was studied in patients with periodontitis of medium severity. The role of selective polishing in arrest of periodontal inflammation was determined on the basis of clinical and rheoparodontographic findings. Terms and stages of selective polishing promoting redistribution of masticatory loading were determined. The effect of this procedure on microvascular tone in the periodontium, essentially affecting the course of periodontal inflammation, is discussed.

[The mechanical action of Dirol chewing gum on the periodontal tissues and masticatory muscles].

Regional hemodynamics, bioelectric activity of masticatory muscles, and compactness of mandibular bone were studied by the rheographic method for measuring periodontal bloodflow, by electromyography, and echo-osteometry in 52 volunteers after 4-week regular chewing of Dirol chewing gum. Congestive hyperemia develops in periodontal tissues; functional activity of masticatory muscles and compactness of mandibular bone are normal.

[A comprehensive study of the mechanical effects of the long-term and regular use of chewing gum].

The results of regular gum chewing (30 min 3 times a day after meals for 4 weeks) were assessed in 46 volunteers by the functional diagnosis methods. Chronometry of food chewing and arbitrary gum chewing for 30 min was carried out before the investigation. Daily duration of food chewing is about 33 min. During gum chewing, the number of masticatory strikes on the inert side is higher during the first 5 min and then levels. This leads to levelling of mechanical loading of the lateral parts of the jaws and of bioelectrical activity in the masticatory muscles proper. The gum is bit 3-5 times more often with frontal teeth than with lateral teeth. Regular use of chewing gum notably increases the blood supply to the periodontium, and the regulatory mechanisms fail to cope with it in periodontal diseases; this leads to venous congestion in the regional vascular system.

[Hemodynamic changes in the periodontium with the use of chewing gum].

The effect of gum chewing (5 min after meals 3 times a day) on periodontal blood supply was studied in a group of 52 volunteers with different clinical status of the periodontium. Tonic strain in the local vessels changed (fluctuated) little (by 2-7%). Tonic strain was shifted on the inert side and in patients with periodontal diseases. Blood consumption increased by 33%. Regular gum chewing for 10 min resulted in compensatory vasoconstriction and hyperemia of the periodontium starting from the second week, irrespective of the initial clinical status of the periodontium.

[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. In initial vasoconstriction functional hyperemia develops without latent period and oscillatory process. A similar picture is observed in periodontal diseases, but the bloodstream volume is far less.

[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.
