Abstract

This study focused on determining the structural framework by oral microbiota in supragingival plaque on a carbonate apatite film applied to human tooth surfaces. The sequential phases of plaque formation over a 3‐wk period were found to be equivalent to those previously reported for natural tooth surfaces. Scanning electron microscopy of specimens prepared by vertical sectioning demonstrated the organization of two types of framework between certain genera of initial and secondary colonizers in the pre‐ and post‐organization phases, respectively. The initial colonizers in the pre‐organization phase were of a coccoid type, while colonizers in the post‐organization phase were of a bacillary type. Secondary colonizers, filamentous cells, were common to both frameworks. Transmission electron microscopy using freeze‐substitution and immunohistochemistry demonstrated two types of coaggregation, fibril‐ and saliva‐mediated modes, among the plaque microbiota. Coaggregation between microbiota, which organized the framework, showed a tendency to occur in the fibril‐mediated mode, and the filamentous secondary colonizers were characterized by inducing multigeneric coaggregation. The present findings indicate that a structural framework and specific cells to form this framework are essential for plaque formation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
