SIGNIFICANT CORRELATIONS BETWEEN THE BULK OF THE DESQUAMATED EPITHELIUM, LACTOBACILLUS, STREPTOCOCCUS, AND VEILLONELLA COUNTS OF THE HUMAN MOUTH

抄録

Correlation among the bulk of epithelial sediment in a gargled water and the Lactobacillus, Streptococcus and Veillonella counts were examined. The results obtained were as follows:
1. A majority of the sediment in a gargled water consisted of epithelial sediment, 82.6% of desquamated cells and 11.9% nucleal residue of the epithelial and salivary corpuscles. A bulk of the oral microorganisms was negligible.
2. Strong correlations were found between any two of the epithelial sediment, Lactobacillus, Stretococcus, and Veillonella; namely 0.910 between the sediment and Str. mitis, 0.901 between sediment and total Streptococcus, 0.865 between sediment and Veillonella, 0.694 between sediment and Lactobacillus, 0.475 between sediment and Str. salivarius, 0.819 between Veillonella and Lactobacillus, 0.867 between Veillonella and total Streptococcus, and 0.753 between Lactobacillus and total Streptococcus.
3. The statistical analysis disclosed that Veillonella was involved in the glycolytic layer, and the role of this newly joined organism in the glycolytic layer was discussed.
4. Factors controlling the desquamation of oral mucosa may simultaneously play a role in maintaining an intraoral population of every member of the glycolytic layer.
5. DMFT did not indicate the existence of a significant relationship to counts of any one of the glycolytic layer but to disquamation.
