Vitamin D may ward off tooth decay: Study Saturday, December 01, 2012 -
 VITAMIN D is associated with a 50 per cent reduction in tooth decay, according to new research.The new review of studies of children in several countries highlighted the potential role for vitamin D in helping to prevent tooth decay or dental caries.The review, published in the journal Nutrition Reviews, encompassed 24 controlled clinical trials, spanning the 1920s to the 1980s, on approximately 3,000 children in several countries.
 These trials showed that vitamin D was associated with an approximately 50 per cent reduction in the incidence of tooth decay. In the trials Dr Philippe Hujoel from University of Washington reviewed, vitamin D levels in children were increased through the use of supplemental UV radiation or by supplementing the children‘s diet with cod-liver oil or other products containing the vitamin.
 The clinical trials he reviewed were conducted in the United States, Great Britain, Canada, Austria, New Zealand and Sweden. Trials were conducted in institutional settings, schools, medical and dental practices, or hospitals. The subjects were children or young adults between the ages of 2 and 16 years, with a weighted mean age of 10 years. Hujoel‘s findings come as no surprise to researchers familiar with past vitamin D studies. According to Dr Michael Hollick, professor of medicine at the Boston University Medical Center, “the findings from the University of Washington reaffirm the importance of vitamin D for dental health”.....
