Appropriate uses of fluorides for children: guidelines from the Canadian Workshop on the Evaluation of Current Recommendations Concerning Fluorides.
OBJECTIVE
To prevent fluorosis caused by excessive fluoride ingestion by revising recommendations for fluoride intake by children.


METHODS
Limiting fluoride ingestion from fluoridated water, fluoride supplements and fluoride dentifrices.


RESULTS
Reduction in the prevalence of dental fluorosis and continued prevention of dental caries.


METHODS
Before the workshop, experts prepared comprehensive literature reviews of fluoride therapies, fluoride ingestion and the prevalence and causes of dental fluorosis. The papers, which were peer-reviewed, revised and circulated to the workshop participants, formed the basis of the workshop discussions.


METHODS
Recommendations to limit fluoride intake were vigorously debated before being adopted as the consensus opinion of the workshop group.


RESULTS
Decrease in the prevalence of dental fluorosis with continuing preventive effects of fluoride use. The only significant cost would be in preparing new, low-concentration fluoride products for distribution.


CONCLUSIONS
Fluoride supplementation should be limited to children 3 years of age and older in areas where there is less than 0.3 ppm of fluoride in the water supply. Children in all areas should use only a "pea-sized" amount of fluoride dentifrice no more than twice daily under the supervision of an adult.


RESULTS
These recommendations are almost identical to changes to recommendations for the use of fluoride supplements recently proposed by a group of European countries.


BACKGROUND
The workshop was organized by Dr. D. Christopher Clark, of the University of British Columbia, and Drs. Hardy Limeback and Ralph C. Burgess, of the University of Toronto, and funded by Proctor and Gamble Inc., Toronto, the Medical Research Council of Canada and Health Canada (formerly the Department of National Health and Welfare). The recommendations were formally adopted by the Canadian Dental Association in April 1993.
