As the editors of the prestigious medical journal anticipated, the newly published Canadian study is causing a stir.
The paper, which appears in JAMA Pediatrics links higher fluoride consumption by pregnant women with lower intelligence scores in their offspring. The findings represent the latest foray by researchers into fluoride safety, an emotionally fraught topic in both the U.S. and Canada.
The authors of the paper studied fluoride exposure for 512 mother-child pairs, about 40% of whom lived in fluoridated communities across six Canadian cities. They calculated fluoride levels in local water supplies and fluoride concentrations in the pregnant women’s’ urine.
Last fall, oral health advocates joined a successful push to save a city water fluoridation ordinance in Rugby, N.D.
Meanwhile, in Buda, Texas, voters rejected a measure that would have reinstated water fluoridation in their Austin suburb. Continue reading
Children living in counties with fluoridated water have significantly less tooth decay than those living in counties that lack water fluoridation programs, according to a newly published large-scale study.
Reduced decay rates were most pronounced in the primary teeth of children living in fluoridated counties. Yet community water fluoridation (CWF) also was credited with conferring a meaningful level of protection to the permanent teeth of children and adolescents. Continue reading
The ongoing controversy over community water fluoridation is unlikely to go away despite a recent U.S. Environmental Protection Agency (EPA) ruling that won praise from the American Dental Association (ADA) and similar groups.
The EPA denied a petition filed by groups seeking to ban the addition of fluoride to community water systems, a longtime practice aimed at reducing tooth decay. Critics of the practice, led by the Fluoride Action Network, contend that that fluoride supplementation poses neurotoxic risks to the U.S. population. Continue reading
It took engineering and fundraising efforts as well as years of work by oral health and children’s advocates, but the Santa Clara Water District is finally providing fluoridated tap water to large sections of San Jose, Calif.
The sprawling city, with a population of more than 1 million, had been known as the largest metropolitan jurisdiction in the nation that lacked a fluoridated drinking water program. The decay-fighting mineral will be phased into water supplies as upgrades to the city’s water treatment plants are completed. Continue reading
Tooth decay rates among children in Calgary, Canada have spiked in recent years.
The authors of two newly published studies say they suspect a decision by Calgary officials to discontinue the city’s water fluoridation program in 2011 could be to blame. Continue reading
