Variability in the ingestion of toothpaste by preschool children.
The amount of dentifrice used and ingested on three occasions by a group of 48 children aged between 3 and 5 years was measured. The purpose of the present study was to investigate the variability in the amount of dentifrice used and ingested. The quantity of toothpaste ingested was derived from the differences between the amounts used and rejected. On average, the difference in the amount used between any two brushings was less than 0.250 g for 66% of the subjects, and the difference in the amount ingested was less than 0.100 g for 69% of the children. There were no statistically significant differences in the quantities used and ingested between the three brushings.
