Fig. 5From: Vinegar inhibits the formation of oral biofilm in situTotal globular particle numbers of the 3-min pellicle detected by SEM were counted. The enamel surface kept quite clean after rinsed with vinegar within 120 min over time. After rinsing with water, there were significant differences compared to the vinegar group immediately (p < 0.01), in 30 min (p < 0.001) and in 120 min (p < 0.001) after rinsing. ** p < 0.01, ***p < 0.001Back to article page
