Abstract

The majority of total ingested fluoride is obtained from dietary source and dental products in nonfluoridated areas. Since the dietary fluoride intake of Korean young children and adults is not known, a study was designed to determine the dietary fluoride intake of 2-4-year-old children and 28-39-year-old females residing in nonfluoridated Seoul. Parents of 25 young children and 23 female adults duplicated quantitatively and qualitatively all foods that the young children and females, ingested during 24-hours. Homogenated food samples were ashed, and then fluoride was isolated by the hexamethyldisiloxane diffusion method during 24 hours. And fluoride ion concentration was measured with an ion-specific combination fluoride electrode. Daily fluoride intakes of female adults and young children were calculated, and estimated from standard diet table. The obtained results were as follows
1. Dietary fluoride intake of female adults was 1.260±0.366 mg/day and the intake of young children was 0.650±0.220 mg/day.
2. Mean daily dietary fluoride intake of young children was 0.046±0.016 mg/kg body weight.
3. Estimated dietary fluoride intakes from standard diet table were 1.538 mg/day for female adults, 2.091 mg/day for male adults and 0.759 mg/day for young children.
4. Dietary fluoride intake of Seoul citizens was less than the recommended intake for dental caries
prevention. Therefore, it is recommended that community water fluoridation be implemented in Seoul.
