摘　　要：目的探讨儿童乳牙根尖周炎感染的根管菌丛构成情况,从而为临床相关防治实践工作提供借鉴和参考。方法选取2016年7月-2017年8月我院口腔科初诊为乳牙根尖周炎患者44例为研究对象,根据患者症状轻重,将其分成急性炎症组和慢性炎症组,分别为16例和27例。对两组儿童乳牙根尖周炎感染的根管菌丛进行分析。结果⑴急性炎症组和慢性炎症组患者的需氧菌、厌氧菌、混合感染患者检出分别为2例、14例、14例和5例、26例和26例,患者各种菌检出率组间比较,差异不大,且无统计学意义;⑵两组患者共计检出410株,急性炎症组和慢性炎症组患者的专性厌氧菌菌属和兼性厌氧菌菌属分别为135株、12株和200株、63株,检出率组间比较差异无统计学意义;⑶急性炎症组和慢性炎症组患者检出的类杆菌、梭杆菌、韦永氏菌、消化链球菌、真细菌分别为42株、20株、10株、53株、8株和40株、9株、24株、97株、17株。类杆菌和梭杆菌检出率组间比较急性炎症组高于慢性炎症组,且差异显著;⑷急性炎症组检出的链球菌和放线菌分别为10株、2株,慢性炎症组检出的链球菌、放线菌、乳杆菌和未定菌分别为41株、9株、3株和10株。检出率组间比较差异无统计学意义。结论儿童乳牙根尖周炎感染患儿致病菌以厌氧菌为主,急性炎症患者的类杆菌和梭杆菌检出率较高,在疾病的发展过程中发挥重要作用,临床实际中应根据根管菌丛分析结果有针对性的实施诊治,以提高临床治疗效果改善临床症状。Objective To investigate the composition of root canal tuberculosis in children with deciduous periapical periodontitis,so as to provide reference for clinical practice.Methods 44 patients with apical periodontitis in our hospital from July 2016 to August 2017 were chosen as the research objects.According to the severity of the patients,the patients were divided into the acute inflammation group(16 cases)and the chronic inflammation group(27 cases).The root canal tuberculosis of apical periodontitis in deciduous teeth was analyzed.Results⑴There were 2 cases and 5 cases for aerobic bacteria,14 cases and 26 cases for anaerobic bacteria,14 cases and 26 cases for mixed infection of patients were detected in acute inflammation group and chronic inflammation group,respectively.There were no significant differences between the detection rates of various bacteria in the patients,and there was no statistical significance.⑵A total of 410 patients were detected in the two groups.The patients with acute anesthesia and facultative anaerobacterium were 135 cases,12 cases,200 cases and 60 cases,and there were no statistical significance between the detection rates of two groups.⑶The detected Bacteroides,Fusobacterium,Vygrenatic,Streptococcus,Streptococcus of patients with acute inflammation and chronic inflammation were 42 cases,20 cases,10 cases,53 cases,8 cases and 40 cases,9 cases,24 cases,97 cases,17 cases.The detection rates of Bacteroides and Bacteroides in the acute inflammatory group were higher than in the chronic inflammatory group,and the differences were significant.⑷Streptococcus and actinomycetes detected in acute inflammation group were 10 cases,2 cases.In the chronic inflammatory group,there were 41 cases,9 cases,3 cases and 10 cases of Streptococcus,actinomycetes,Lactobacillus and Undetermined bacteria.There were no significant differences between the detection rates.Conclusion The pathogens of children with deciduous periapical periodontitis are mainly anaerobic bacteria.The detection rate of Bacter
