目的:检测和比较有瘘型与无瘘型根尖周病感染根管内优势菌丛的分布特点.方法:选择60位慢性根尖周炎患者共64颗患牙,在对每个患牙进行根管治疗的过程中,髓腔预备及根管初预备后,用无菌纸尖吸取根管内容物进行采样,置入无菌EP管,于10 min内送至-20℃冰箱保存.对根管内样本进行genomic DNA提取,使用27种选取的由基因公司提供的感染根管内优势菌的引物对上述64例样本进行多重模板扩增,根据扩增产物的有无判断各样本中含有的菌种类型.结果:瘘管的发生与Prevotella nigrescens(变黑普氏菌)、Porphyromonas spp.(卟啉单胞菌)、Peptostreptococcus stomatis(口炎消化链球菌)、革兰氏阴性球菌、Capnocytophaga ochracea(黄褐二氧化碳嗜纤维菌)、Corynebacterium matruchotii(马氏棒杆菌)、Hafnia spp.(哈夫尼菌属)及Eubacterium spp.(真杆菌属)的感染有关.结论:慢性根尖周炎瘘管发生与根管内分离到的Prevotella nigrescens、Porphyromonas spp.、Peptostreptococcus stomatis、革兰氏阴性球菌、Capnocytophaga ochracea、Corynebacterium matruchotii、Hafnia spp.及Eubacterium spp.的特异性定植有关.中国科技核心期刊(ISTIC)中国科学引文数据库(CSCD)0101004-10072
