采用严格的厌氧技术和稳定的实验条件,通过与15例慢性根尖周炎的对照分析,对30例急性根尖周炎患牙根管内厌氧菌的分离培养研究表明:急性根尖周炎是以厌氧菌为主的混合感染,厌氧菌主要分布干类杆菌、梭杆菌、丙酸杆菌、消化链球菌、真细菌和韦荣氏球菌等6属,其中产黑素类杆菌组菌和核梭杆菌菌种与其发生有密切关系;急性根尖周炎是由口腔正常菌群失调所致的内源性感染,厌氧菌与需氧菌以及不同菌属、种之间的协同作用都参与了其发生。
Using strict anaerobic technology and stable experimental conditions, with 15 cases of chronic periapical periodontitis control analysis of 30 cases of acute apical periodontitis with root canal anaerobic bacteria isolated and cultured studies have shown that: acute apical periodontitis Anaerobic bacteria are mainly mixed infections, anaerobic bacteria are mainly distributed in the dry bacillus, Fusobacterium, Propionibacterium, Peptostreptococcus, eubacteria and Veillonella, 6 genera, which produce melanobacteria group of bacteria And Fusobacterium species is closely related to its occurrence; acute periapical periodontitis is caused by the normal oral flora imbalance caused by endogenous infections, anaerobic bacteria and aerobic bacteria, as well as the synergistic effect of different genus, species Have participated in its occurrence.
