Vascular changes after experimentally-induced inflammation in the mandible.

In this study, the vascular supply of an experimentally-induced inflammatory reaction in 5 monkey mandibles is examined. A barium sulfate injection method, combined with contact microradiography was used. In all monkeys, marked vascular changes were seen within the areas of inflammation. Vertical nutrient branches were interrupted shortly after leaving the inferior alveolar artery, and a conglomerate of thin irregular vessels were seen interspersed through newly formed bone trabeculae. The vascular supply to the neighbouring teeth seemed to be unaltered; neither was there any evidence of vascular thrombosis or vasculitis.
