[Morphofunctional parallels in the development of pulpitis].

In 16 mongrel dogs rheodontography was applied to study the functional state of inflamed dental pulp blood vessels. At the same time, pathological investigation of the pulp tissues was performed within 1 h to 40 days after the pulpitis modelling. Direct correlation of purulent-infiltrative pulp changes in acute and chronic inflammation with rheodentographic features was shown. The rheodentographic technique was shown effective for intravital diagnosis of the acute and chronic dental pulp inflammation.
