Summary

Young children may ingest excessive fluoride from toothpaste. Toothpaste quantity used increases with age, but swallowing 15-30% poses a risk for 3- and 7-year-olds using high-fluoride toothpaste.

Area of Science:

  • Pediatric Dentistry
  • Public Health Nutrition
  • Fluoride Toxicology

Background:

  • Toothpaste consumption varies by age and is influenced by tube design.
  • Young children often swallow a significant portion of toothpaste during brushing.
  • Assessing fluoride intake from dentifrice is crucial for pediatric oral health.

Purpose of the Study:

  • To quantify dentifrice usage in Danish children across different age groups.
  • To investigate the relationship between tube orifice diameter and toothpaste amount used.
  • To evaluate potential fluoride over-ingestion risks in young children.

Main Methods:

  • Studied 179 Danish children aged 3, 7, 9, and 16 years.
  • Measured aggregated dentifrice quantities used at home over two weeks.
  • Collected data on toothbrushing habits and tube orifice diameters.

Main Results:

  • Mean daily toothpaste usage increased with age, from 1.1g (3-year-olds) to 3.4g (16-year-olds).
  • Higher toothpaste usage correlated positively with larger tube orifice diameters.
  • Despite similar ribbon lengths, younger children's swallowing habits increase fluoride ingestion risk.

Conclusions:

  • A significant number of 3- and 7-year-olds may exceed recommended daily fluoride intake.
  • Toothpaste tube design (orifice diameter) impacts overall consumption.
  • Careful monitoring of toothpaste use and fluoride content is essential for young children.
