Relationship between XXXX and those in saliva.

@entity6586 @entity2413 @entity885
A variety of indices has been developed for the quantitation of dental plaque. The aim of this study was to determine the correlation between the L  e plaque index and the number of bacteria on the same tooth. Furthermore, the effect of plaque accumulation on the salivary counts of some @entity2413 was estimated. Twenty volunteers were asked to abstain from all oral hygiene for a one-week period. Clinical indices and bacteriological samples were taken at the start and at the end of the experimental period. After an interval of seven days, the experiment was repeated. The relationship between the L  e plaque index and the total bacterial counts on the same area of the tooth was found to be highly significant. After seven days without oral hygiene, the total counts and the Actinomyces viscosus/naeslundii and @entity885 counts in dental plaque had increased by approximately two log units, while the @entity6586 counts had increased by more than one log unit. The large increase in the number of bacteria on the teeth was reflected in the salivary counts of the Actinomyces species, but not in the @entity885 or @entity6586 counts. This was due to differences in ecological habitats of these species in the mouth. Highly significant correlations were found between the @entity6586 level in dental plaque and the salivary level, and between the @entity6586 counts of the subjects in the first and second trials of the experiment.
