Since November 28, 1985, fluoridated salt at a concentration of 250 mg KF per Kg has been authorized in food in France. It was introduced in the market at the end of 1986 and represented, in 1993, more than 60% of the market of salt. The effect of this Public Health measure will be shown. The efficiency is evaluated in epidemiological studies concerning DMF in the whole of France and in terms of safety by measurement of urinary excretion of fluoride in children who consume potassium fluoride in the salt and fluoride tablets. Last, the prevention policy in France will be described, including the use of fluoridated salt.
In 1951, A. Dahlberg took casts of 82 children aged 8-17 who lived in the Sac-Fox Settlement near Tama, Iowa. In 1990, the Indian Health Service supported a survey of 44 survivors from the 1951 study. All were contacted and 23 were examined. The findings from this study were compared with findings from similar aged Sac-Fox residents surveyed in 1982, and with the residents of Iowa of a similar age surveyed in 1980. The DMFS score of the 1990 Sac-Fox samples was larger (92.4) than that for the Iowa Survey (75.3). The periodontal findings were similar in the three samples, with one exception, the category 6+mm pockets were seen more frequently in the 1990 Sac-Fox sample (13.0%) than in the 1982 Sac-Fox (8.7%) and 1980 Iowa (2.9%) samples. Mucosal lesions were observed much more frequently in the Sac-Fox 1990 (69.6%) and 1982 (65.2%) samples, compared to the 1980 sample (8.6%). The frequency of totally edentulous persons was also much greater in the Sac-Fox samples, as compared to the Iowa Sample. It appears that the 1982 recommendations for making preventive procedures available to Sac-Fox adults is still appropriate in 1990.
