研究根尖周炎根管内微生物之间是否存在亲合力或拮抗关系。从65个感染的人根管中取样，并根据总分离植物群的种类、发生频率和比例进行分析。最常见的菌种为具核梭杆菌、中间普雷沃氏菌、微小消化链霉菌、厌氧消化链霉菌、解乳真杆菌、迟缓真杆菌和直窝氏菌。优势比系统用于计算分离的细菌之间的阳性或阴性关联。F. nucleatum和P.micros、牙髓卟啉单胞菌（Porphyromonas endodontalis）、生痰月形单胞菌（Selenomonassputigena）和W.直肌中间型P与微小型P、厌氧型P与真细菌之间也存在正相关。一般来说，链球菌、丙酸杆菌、赭色二氧化碳嗜纤维菌和小韦荣球菌与其他细菌没有相关性或呈负相关性。结果是一致的概念发生在根管中的一个特殊的和选择性的环境，这是由于，在一定程度上，合作以及根管中的细菌之间的关系的拮抗性质。
The existence of commensal or antagonistic relationships between microorganisms in the root canals of teeth with apical periodontitis was investigated. Samples were taken from 65 infected human root canals and were analysed according to species, frequency of occurrence and proportion of the total isolated flora. The most frequent species were Fusobacterium nucleatum, Prevotella intermedia, Peptostreptococcus micros, Peptostreptococcus anaerobius, Eubacterium alactolyticum, Eubacterium lentum and Wolinella recta. An odds ratio system was used to calculate positive or negative associations between the isolated bacteria. Strong positive associations were found between F. nucleatum and P. micros, Porphyromonas endodontalis, Selenomonas sputigena and W. recta. There was also a positive association between P intermedia and P micros, P anaerobius and the eubacteria. In general, species of streptococci, Propionibacterium propionica, Capnocytophaga ochracea and Veillonella parvula showed no or negative associations with the other bacteria. The results are consistent with the concept of a special and selective environment occurring in the root canal that is due, in part, to the cooperative as well as antagonistic nature of the relationships between bacteria in the root canal.
