摘要 目的研究老年人根面龋牙菌斑内细菌群落构成,以期为今后深入研究根面龋的病因提供依据。方法提取9例60岁以上根面龋患者9颗患牙的牙菌斑细菌DNA,应用聚合酶链反应一变性梯度凝胶电泳(PCR-denaturing gradient gelelectrophoresis,PCR-DGGE)技术扩增,克隆、测序并与核酸序列数据库进行比对,鉴定优势菌属种类。结果老年人根面龋牙菌斑中共检测到114个细菌基因型,分属于不动杆菌属[0.9%(1/114)]、放线杆菌属[1.8%(2/114)]、放线菌属[15.8%(18/114)]、Aggregatibacter菌属[0.9%(1/114)]、二氧化碳嗜纤维菌属[14.0%(16/114)]、棒状杆菌属[0.9%(1/114)]、嗜血杆菌属[0.9%(1/114)]、动弯杆菌属[0.9%(1/114)]、纳西杆菌属[0.9%(1/114)]、奈瑟球菌属[10.5%(12/114)]、卟啉单胞菌属[0.9%(1/114)]、普氏菌属[12.3%(14/114)]、新月单胞菌属[6.1%(7/114)]、葡萄球菌属[1.8%(2/114)]、口腔链球菌群[6.1%(7/114)]和变异链球菌群[7.9%(9/114)]、Tannerella菌属[0.9%(1/114)]、密螺旋体[1.8%(2/114)]和韦永球菌属[10.5%(12/114)],以及两例未获培养的不知名菌种[1.8%(2/114)]。未获培养的基因型占总数的19.3%(22/114)。革兰阳性细菌的基因型占31.6%(36/114),革兰阴性细菌的基因型占66.7%(76/114)。结论老年人根面龋牙菌斑中细菌基因型多且分布较广,以革兰阴性菌占多数;未发现特异性致龋细菌基因型。 Objective To analyze the community in dental plaque of elder people with root caries. Methods Total DNAs were extracted fi'om the root caries dental plaques of nine eiders over 60 years of age. Polymerase ehaid reaction-based denaturing gradient gel electrophoresis (PCR-DGGE) was used to analyze the microbial composition, DGGE bands were excised from the gels for sequencing and identification. Results The dominant genus in root caries dental plaque of elder people were: Aciuetobacte [0. 9% (1/114) ], Actinobaculum [ 1.8% ( 2/114 ) ], Actinomyces [ 15.8% ( 18/114 ) ], Aggregatibacter [0. 9% (1/114) ~, Capnocytophaga [ 14. 0% ( 16/114 ) ], Corynebacterium [ 0. 9% ( 1/114 ) ], Haemophilus [0. 9% ( 1/114 ) 1, Mobiluncus [ 0. 9% ( 1/114 ) ], Naxibacter [ 0. 9% ( 1/114 ) 1, Neisseriaceae [ 10. 5% (12/114) 1, Porphyromonas [ 0. 9% ( 1/114 ) 1, Prevotella [ 12. 3% ( 14/114 ) ], Selenomonas [ 6. 1% (7/114) 1, Staphylococcus [ 1.8% (2/114)], Oralis streptococcus [6. 1% (7/114)], Mutans streptoeoccu [7.9% (9/114) ], Tannerella [0.9% (1/114)1, Treponema [1.8% (2/114)], Veillonella [ 10.5% (12/114)1 and two uncultured unknown genus[ 1.8% (2/114)]. Uncuhred genotypes accounted for 19.30% of the total. Gram-positive bacteria genotype accounted for 31.6% (36/114) , and Gram-negative bacteria genotype accounted for 66.7% (76/114). Conclusions There were many bacteria genotypes in root caries dental plaque in the elderly, which were widely distributed. Gram-negative bacteria accounted for the majority. Genotype-specific pathogenic bacteria were not found.
