| 摘 要： | 目的 通过对原位菌斑生物膜发育过程及早期成熟菌斑生物膜的观察,探讨所建立的菌斑生物膜模型用于菌斑化学干预研究的可能性.方法 建立原位菌斑生物膜模型,运用激光共聚焦扫描显微镜结合荧光染色技术观察原位菌斑生物膜0～48 h的发育过程及48 h菌斑生物膜的活性和厚度.结果 可观察到0～48 h菌斑生物膜从无到形成到成熟,细菌排列趋于密集,菌斑厚度逐渐增加的过程.48 h的菌斑生物膜活性和厚度可检测.结论 建立的菌斑生物膜模型可观察原位菌斑的形成过程、形态及活性,适用于菌斑化学干预的研究.

| Abstract: | Objectives To explore whether the established model of dental plaque biofilm can be used in the research of chemical intervention on plaque biofilm via observing the development of biofilm and the vitality of earlier mature biofilm plaque. Methods An in vivo biofilm model was established. The development of biofilms in 48 hours in vivo was observed and the vitality and thickness of earlier mature biofilms were measured by confocal laser scanning microscope and the vital fluorescence techniques. Results The ... |
