However, the features of microbial habitation in dental plaque, which are considered to induce dental caries and periodontitis, has not been clarified thoroughly. To clarify the features of microbiota in dental plaque, this study morphologically investigated supragingival dental plaque on a carbonate apatite film applied to human natural tooth surfaces for 8-20 days. The morphology of microbial habitation in plaque was confirmed to be identical to that in plaque on human natural tooth surface under poor oral hygiene. Old plaque formed after an 8-day exposure to the oral environment exhibited a tendency for the microbial flora to preserve stationary state, especially two layers consisting of grampositive bacillary type (initial colonizer) and gram-negative filamentous type (secondary colonizer) without showing remarkable change. From the above, it was concluded that the dental plaque at the stage regarded to be deeply related to the initiation of oral infections such as dental caries and periodontitis shows a basic arrangement of microbiota formed between bacillary initial and filamentous secondary colonizers and gram-negative cocci and bacilli on the surface of the basic arrangement. These major microbiota were identified as Actinomyces and streptococci (initial colonizer) by immunoelectron microscopy. Fusobacterium (secondary colonizer) and Porphyromonas gingivalis (predominant microbiota on the surface of the basic arrangement) then sequentially accumulate.","subitem_description_type":"Other"}]},"item_10002_full_name_75":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"4611","nameIdentifierScheme":"WEKO"}],"names":[{"name":"YAMADA,
