Summary
Early and substantial fluoride dentifrice use in infants is common, posing a risk for dental fluorosis. Monitoring fluoride intake is crucial for young children
Area of Science:
- Pediatric Dentistry
- Dental Public Health
- Fluoride Toxicology
Background:
- Dental fluorosis is a risk associated with early and high-quantity fluoride dentifrice use.
- Limited data exists on fluoride dentifrice consumption patterns in infants and young children.
- Developing permanent teeth in young children are particularly vulnerable to dental fluorosis.
Purpose of the Study:
- To investigate patterns of fluoride dentifrice usage and ingestion among infants up to 12 months of age.
- To identify potential risk factors for dental fluorosis related to early fluoride exposure.
Main Methods:
- A birth cohort study design was employed.
- Mothers reported on fluoride dentifrice use via written questionnaires.
- Data collected at 6, 9, and 12 months of age included brushing frequency, type of dentifrice, and estimated quantities used.
Main Results:
- Tooth brushing increased significantly from 6 to 12 months (12.9% to 64.5%).
- Fluoride dentifrice use rose from 1.9% at 6 months to 31.7% at 12 months.
- Among dentifrice users, 94-97% used fluoride, with substantial mean daily fluoride intake (0.19-0.21 mg F).
Conclusions:
- Fluoride dentifrice use among infants is variable but can be substantial.
- The quantity of fluoride ingested from dentifrice by infants can be significant.
- Infant fluoride dentifrice use represents a potential risk factor for developing dental fluorosis.
