| 目的 探究微小小单胞菌在慢性根尖周炎感染根管中的定植情况。方法 选取收治的、符合纳入标准的慢性根尖周炎病人138例,共150颗患牙,并采集患牙的根管标本。根据患牙是否为初次治疗,分为初次治疗组(n=75)和非初次治疗组(n=75)。对于根管标本做以下处理:应用16S rDNA PCR技术,检测微小小单胞菌的DNA,并比较两组的检出率差异；对标本检测出的牙龈卟啉单胞菌、牙髓卟啉单胞菌以及粪肠球菌与微小小单胞菌进行关联影响分析。结果 检出率:与非初次治疗组相比,初次治疗组的微小小单胞菌检出率较高,差异有统计学意义(P<0.05)；Logistic回归分析:两组的微小小单胞菌检出情况均与牙髓卟啉单胞菌密切关联(P＜0.05)。结论 微小小单胞菌在慢性根尖周炎定植可能与牙髓卟啉单胞菌存在共生关系。 |

| Objective To explore the colonization of Parvimonas micra in the root canal of chronic periapical periodontitis. Methods A total of 138 cases of chronic periapical periodontitis with the criteria of inclusion criteria were selectedand a total of 150 teethand root canal specimens were collected.According to whether the tooth was first treatment,the cases were divided into initial treatment group (n=75) and non-initial treatment group (n=75).The DNA of Parvimonas micra from root canal specimens were detected by 16S rDNA PCR.The difference were compared between the two groups.The association effects of porphyrin gingivalis,pulp porphyrin and enterococcus faecalis were analyzed. Results Detection rate:Compared with the non-initial treatment group,the detection rate of Parvimonas micra in the first treatment group was higher,with statistical significance (P<0.05)；Logistic regression analysis:The detection of Parvimonas micra in two groups was closely related to pulp Single (P<0.05). Conclusion The colonization of Parvimonas micra in chronic periapical periodontitis may have a symbiotic relationship with pulp Single. |
