Morphofunctional State of the Periodontal Tissues in Humans and Rats with Arterial Hypertension.

We performed comparative analysis of hemodynamic in the periodontal microcirculatory bed in adolescents with arterial hypertension (AH) and morphological changes in the periodontal tissues of in hypertensive ISIAH rats of comparable biological age. In the periodontal tissues of adolescents with hypertension, the blood flow velocity and index of peripheral resistance increased, while pulse pressure decreased. In ISIAH rats, the mean area of periodontal and pulp vessels increased and the area of the connective tissue decreased. These results can be used in the complex assessment of morphofunctional state periodontium during hypertension development.
