[Periapical tissues microvessels reactivity study after pulp extirpation and on different stages of endodontic treatment].

Reaction of the microvessels in the gingival periapical tissues on pulp extirpation was followed by hyperemia development in microcirculatory bed, its expression increased in proportion as parodontal inflammation intensified and further strengthened after root canal filling. Microcirculation normalization in the gingival periapical tissues after endodontic treatment of chronic pulpitis and pulp extirpation as part of endodontic treatment was evident in 1 month in intact parodontium and in 6 months in case of its inflammation.
