A new classification of the angioarchitecture and blood flow is proposed in light of the results of vital microscopy studies of the windowed periodontium and gingiva of the incisors of rats. The flow pattern and the rate of blood flow are different in different vessels. The flow of blood in segmented and interconnected arterial and venous vascular sections in the alveolar and marginal periodontium corresponds to what is known as systemic circulation, whereas that in arterioles, capillaries, and venoles must be considered as belonging to what is referred to as microcirculation. Subepithelially, the microcirculatory elements constitute a nutritive, typically ordered capillary network as contrasted with the random spatial arrangement of capillary loops in the alveolar periodontium. Numerous anastomoses provide the basis for possible functional adaptation, leading to the formation of polygonal ring closures in the alveolar region. The interpretations of functional findings are based upon histotopological reexaminations.
根据对大鼠切牙开窗牙周组织和牙龈进行活体显微镜研究的结果，提出了一种新的血管构筑和血流分类方法。不同血管中的血流模式和血流速度各不相同。牙槽和边缘牙周组织中分段且相互连接的动脉和静脉血管段中的血流与所谓的体循环相对应，而小动脉、毛细血管和小静脉中的血流则必须被视为属于所谓的微循环。在上皮下，微循环元件构成了一个营养性的、典型的有序毛细血管网络，这与牙槽牙周组织中毛细血管袢的随机空间排列形成对比。众多的吻合支为可能的功能适应提供了基础，导致在牙槽区域形成多边形的环闭。功能研究结果的解释基于组织拓扑学的重新审视。
