麦克唐纳、黑尔和伍德以及布朗和鲁道夫已经从完整但受到创伤的牙齿的牙髓组织或根管中分离出微生物。2.健康、无龋的牙齿在外伤后发生急性或慢性脓肿并不罕见。在这样的化脓中，微生物已经从化脓物质本身或根管中分离出来。微生物可能到达牙髓的途径是通过牙周组织中的切断血管（微生物的来源是龈沟）或血流，或两者兼而有之。本研究计划通过易于识别的试验微生物粘质沙雷氏菌（通常不存在于犬或猴口腔中）确定创伤、健康牙齿中微生物的来源。
Microorganisms have been isolated from the pulp tissue or root canals of intact but traumatized teeth by MacDonald, Hare, and Wood ~ and by Brown and Rudolph. 2 It is not uncommon for an acute or chronic abscess to develop after trauma to a sound, noncarious tooth. In such abscesses, microorganisms have been isolated from the purulent material itself or from the root canal. The pathways by which microorganisms may reach the pulp are through the severed blood vessels in the periodontium (the source of the microorganisms being the gingival sulcus) or the blood stream, or both. This study was planned to determine the source of the microorganisms in traumatized, sound teeth by means of a readily identifiable test organism, Serratia marcescens, not ordinarily present in the mouths of dogs or monkeys.
