[The characteristics of the functional status of the periodontal circulation following the preparation of pulpectomized teeth under artificial crowns].

Rheoparodontographic findings evidence more profound and manifest shifts in periodontal circulation of pulp-free teeth as against intact teeth after preparation for artificial crowns. Vascular elasticity and distensibility are reduced in pulp-free teeth, vascular tonic tension and periodontal tissue blood content are elevated (according to the inflammatory arterial hyperemia type), peripheral vascular resistance is reduced, and venous blood flow from the periodontal tissues deteriorated.
