Variations in microbial and biochemical components of four-day plaque during a four-week controlled diet period

Variation in microbial and biochemical components of human four-day plaque was studied in seven subjects who were maintained on a high-sucrose diet during a four-week period. Significant changes in populations of lactobacilli dextranase-producing organisms, Streptococcus mutans, and S sanguis occurred during this period.
