This paper introduced a new method which was used to study the formation of dental plaque in vitro. From this investigation, it can be regarded that artificial dental plaque is similar to natural dental plaque in structure. In the 1st day, artificial dental plaque was mainly coccal shaped bacteria adherent on the tooth enamel. At the third day, the number of filaments and rods increased obviously, and in 5th and 7th day plaques, main bacteria were filaments, with a few rods and cocci, and the special palisade and corn cob structures were occurred. The morphology of 2-week, 3-week and 4-week plaque were almost the same, but denser in structure.
本文介绍了一种用于体外研究牙菌斑形成的新方法。通过这项研究，可以认为人工牙菌斑在结构上与天然牙菌斑相似。在第1天，人工牙菌斑主要是附着在牙釉质上的球菌形细菌。在第3天，丝状菌和杆菌的数量明显增加，在第5天和第7天的菌斑中，主要细菌是丝状菌，有少量杆菌和球菌，并出现了特殊的栅栏状和玉米棒状结构。2周、3周和4周菌斑的形态几乎相同，但结构更致密。
