CDC: Dental Caries in Rural Alaska Native Children — Alaska, 2008

This study concludes that tooth decay is higher in rural Alaska. Click here for a news article discussing this study by the State of Alaska and CDC.

The study itself (click here) states:

“Dental caries severity was greater in nonfluoridated villages. Children from nonfluoridated villages had 1.2–2.9 times higher mean dft or DMFT than children from fluoridated villages and 1.2–3.1 times the mean number of decayed teeth. Children from the Alaska region had 1.5–4.5 times the number of dft or DMFT than same-aged U.S. children and 1.6–9.0 times the number of decayed teeth. On age-adjusted bivariate analysis, only lack of water fluoridation, increased soda pop consumption, and infrequent brushing of teeth were significantly associated with dental caries severity in primary and permanent teeth (all p-values <0.05).”

Lack of water fluoridation is implicated,
