[Masticatory loading influence upon dental pulp functional status and its blood supply].
By pheodentography and Doppler laser flowmetry in 53 volunteers with clinically healthy parodontal tissues or parodontitis of light degree the masticatory teeth dental pulp functional status and its blood supply including microcirculation was studied. It was established that in case of one-sided type of chewing masticatory loading reduction on nonworking side increased vessel's tonus and capillary blood flow level. In case of regular use of chewing gum and filbert nuts vasoconstriction was developed, blood supply was considerably reduced and capillary blood flow level in the pulp was sharply increased that made up its functional adaptive mechanism of defense for the provision of plastic odontoblast function.
