March 24, 2017 -- SAN FRANCISCO - Reducing community water fluoridation to 0.7 mg/L appears to be effective at reducing fluoride exposure while still preventing caries, according to research presented at the International Association for Dental Research (IADR) annual meeting.
Helen Whelton, BDS, MDPH, PhD.
A team of scientists from Ireland and the U.K. compared the caries incidence rates before and after Ireland lowered the recommended water fluoridation level from 0.8-0.9 mg/L to 0.6-0.8 mg/L in 2007. They found that the lower fluoridation rate did not increase caries levels.
"Caries levels did not increase following the reduction in fluoride levels, and there was no increase in caries between 2002 and 2013/2014," said Helen Whelton, BDS, MDPH, PhD, in her presentation at the IADR annual meeting.
Dr. Whelton is a professor of dental public health and preventive dentistry and the dean of the University of Leeds School of Dentistry in the U.K.........................
.......In addition, they found that caries levels were still dramatically lower for kids in fluoridated counties than those living in counties without community water fluoridation. In fact, living in an area with fluoridated water reduced the odds of a child having caries by about 46%.
46% - do we believe it?
