采用厌氧试管培养技术，对与青少年牙周炎相关的晚期组织破坏（牙周袋）和无附着丧失的对照牙周袋的主要可培养菌群进行定量和定性检查。对照部位的微生物群落主要由链球菌、革兰氏阴性杆菌和革兰氏阳性杆菌组成。相比之下，测试口袋有一个相对稳定的和特征性的微生物群落，占主导地位的各种革兰氏阴性，厌氧杆。革兰氏阴性杆菌被分为几个主要的组，但使用的方法和可用的数据不能对许多这些微生物进行令人满意的分类。占主导地位的革兰氏阴性杆菌不同的个体。革兰氏阴性杆菌在青少年牙周炎病因中的作用尚不清楚。这些微生物的一些潜在的致病机制进行了讨论。
Quantitative and qualitative examinations of the predominant cultivable microflora of the advanced tissue destruction (pocket) associated with juvenile periodontitis and of control pockets without loss of attachment were carried out by using anaerobic tube culture technique. The microflora from the control sites consisted primarily of streptococci, Gram-negative rods, and Gram-positive rods. In contrast, the test pockets had a relatively stable and characteristic microflora, dominated by various Gram-negative, anaerobic rods. The Gram-negative rods were divided into main groups, but a satisfactory classification of many of these microorganisms could not be performed with the methods used and the data available. The predominating Gram-negative rods differed from individual to individual. The role of the Gram-negative rods in the etiology of juvenile periodontitis is unknown. Some potential pathogenic mechanisms of these microorganisms are discussed.
