Yay for fluoride

The Guardian has a story up about how Queensland is a good way to track the effectiveness of fluoridation of water:
Dentists and doctors in Queensland are reporting “extensive tooth decay” in parts of the state that refuse to add fluoride to the water supply, especially among children and the elderly.

One in four Queensland children admitted to hospital requires treatment for a dental condition, according to the most recent report by the state’s chief medical officer.

Indigenous children, many of whom live in communities without fluoride, have a staggering 70% rate of tooth decay. The rate is 55% among all Queensland children aged between five and 15.

The thing is, the State government has left it up to Councils to decide on the matter, with some not doing it citing cost concerns, but there are also anti-fluoride activists playing a role (or trying to) as well.  Which means you get evidence like this:
In Bundaberg, which does not have fluoride, the rate of tooth decay is about 2.5 times higher than the rest of the state. There were 244 admissions to hospital for dental conditions in the town last year. Across the state, the number is in excess of 4,000....

Neil Johnson, the foundation dean of the Griffith University dental school and an emeritus professor, has been involved in a long-running study of dental heath in a Cape York Indigenous community.

Fluoride was added to the water supply in 2006. About six years later, there had been “a considerable improvement” in the health of the community, and about a 40% reduction in tooth decay.
