摘要
目的:研究复合树脂和银汞合金充填体周缘继发龋的细菌组成。方法:充填体周缘继发龋采样,常规培养鉴定。结果:继发龋的主要优势菌为不产黑色素普雷沃菌、产黑色素普雷沃菌等。每组中各种细菌的几何均数之间有显著差异(P<0.05)。每组中各菌种占可培养菌的百分比之间有显著差异(P<0.05)。每组中各菌种的检出率有显著差异(P<0.05)。结论:继发龋的主要优势菌为不产黑色素普雷沃菌、产黑色素普雷沃菌、韦荣菌、乳杆菌、变形链球菌、奈瑟菌,其次为放线菌、核梭杆菌、消化链球菌、牙龈卟啉菌。
Objective： To compare the microbial spectrum around amalgam and composite resin restorations in classⅠ and Ⅱ cavities.Methods： Clinical samples from marginal gaps of the restorations were inoculated onto special agars.The bacteria spectrum was identified by KLDBME system.Results： The bacteria of secondary caries included primarily Prevotella,Veillonella,Lactobacilli,Streptococci mutans and Neisseriae.In each group the geometric mean of the detected bacteria had statistical difference（P0.05）.Although the percent of each detected bacteria had no statistical difference among the four groups（P0.05）.In each group the percent of the detected bacteria was significantly different（P0.05）.The prevalence of the detected bacteria had statistical difference in each group（P0.05）.Conclusion： The bacteria of secondary caries include obligate anaerobic species and facultative anaerobic species.
