[Vital microscopic examination of the periodontal blood circulation of incisors in rats (author's transl)].
This paper describes a method of making microscopic in vivo examinations of the periodontal blood vessels of the lower incisors in rats. On an anesthetized animal, part of the lower jaw is laid open by a U-shaped skin incision and the ligament joining the halves of jaw is cut through. After macrosopic and microscopic preparation, the circulation of blood in the exposed marginal gingiva or in the windowed periodontal space may be observed in vivo by transmitted-light microscopy. The standardized biological model enables the structure and function of the periodontal blood vessels and their normal and disturbed mechanisms of regulation to be examined and compared with conventional histological findings. The functional and morphological parameters are representative of the human periodontium.
