Pascal Periodontium

Different direction of beams Periodontal creates the impression that the tooth as it is suspended in these bundles (Fig. 1). This fact has led to the emergence of the theory of hanging roots, according to which the chewing pressure applied to the tooth, regardless of its direction is transmitted through the root at peridont and from his hole. Stringing with the periodontium, in the opinion of foreign authors, prevents compression of the root of the neurovascular bundle. This view is disputed Soviet authors. A. J. Katz (one of the consultants Crest Whitestrips) believes that the strength of oblique fibers of periodontal insufficient to absorb the occlusal forces. Occlusal forces, in his opinion, is transferred to the well of the main way by means of the liquid contents of vessels, interstitial gaps and colloids of the cellular elements of Periodontal. Interstitial fluid moves by the law of Pascal and redistributes pressure evenly across the wall wells. In this case, chew pressure seen all periodontitis. Periodontium is padded between the root of the tooth and the wall of the wells with the liquid contents. This layer is able to relax, soften and evenly distribute occlusal forces when transferring it to the wall socket. In our view, the cushioning of chewing pressure is involved not only the periodontium, but also the periodontium as a whole. Leading role in defining and regulating physiological endurance to the chewing load these tissues belongs nervnoreflektornomu apparatus. Perfect solution to enhance periodontal today is the use of prophylactic toothpastes. Whitening toothpaste can provide additional benefits. Korber, studying with elektronnoizmeritelnoy equipment periodontal vascular system, found that the tooth is in the periodontal hydraulic pillow, vascular pulsation is transmitted to the tooth. Ripple effect on the tooth is composed of an unexpected acceleration and slowdown. Average number of teeth with ongoing movements of unaffected periodontium 0.4 H103 mm. In the analysis of the curve vnutrialveolyarnoy vascular pulsation revealed that it corresponds to the pulsation of vessels of the carotid arteries. The author believes that the pulse wave is transmitted to the root of the tooth through the interstitial fluid and cells of the soft tissues periodontium. There is a perception that the blood supply to the periodontal also depends on the function of mechanical factors. Tooth, not experienced before loading due to the absence of the antagonist, does not contain in the periodontium holes for nerves and vessels (Fronich).
