title: [The microcirculation in the periodontal tissues: I. The dynamics of functional hyperemia].
abstract: Study of functional hyperemia of the gingival microcirculatory network by biomicroscopy and laser Doppler flowmetry showed that in normal periodontium, the microcirculation index increased by 70% immediately after mechanical loading created by the gnathodynamometer, whereas in slight or medium-severe periodontitis it increased only by the and of the first minute, the peak bloodflow values being 31 and 19%, respectively. In grave periodontitis the microcirculation index was 6% decreased immediately after loading and increased only by the fifth minute, which is explained by notable changes in the angioarchitectonics of periodontal microvessels.
