ABSTRACT
Daily supplementation of a high sucrose diet with 5 gm TMP resulted in significant alterations in certain human plaque components. Veillonella and Neisseria population (as percent total viable microorganisms), S sanguis (as percent streptococci), and levan hydrolase activity per milligram of plaque increased, whereas total viable microorganisms per milligram of plaque, streptococci per milligram of plaque, and specific fructosyltransferase activity decreased during the TMP-containing diet regimen.

The effects of dietary sucrose levels on the microbial composition of 4- and 12-day plaque were investigated in eight dental students. Sucrose-rich diets had no demonstrable effects on total plaque accumulation, whereas total viable microbial density, Streptococcus mutans, and the lactobacilli populations increased. The S sanguis population was unaffected. However, in individual subjects, an inverse relationship between the S sanguis and S mutans population was observed.
