title: [Types of interbacterial coaggregation in dental plaque].
abstract: Scanning electron microscopic observations of teeth-gingiva fragments removed among children or dogs made an important contribution to our knowledge of the composition of the microbial flora in gingival crevice. It was possible to appreciate special relationships between forms as "corn-cob" or "bristle brush" arrangements. The development of these formations were observed: coccal form apposition preceded corn-cob organization; abundant extra-cellular amorphous material preceded bristle brush arrangement. Inter or/intra bacterial calcification models are proposed to explain calculus formation.
