Flawed foundation: a re-examination of the scientific basis for a dental benefit from fluoridation.
The scientific basis for a dental benefit from water fluoridation is critically examined. Professional responses and the "mind set" about fluoridation are described and discussed.

Influence of social class and fluoridation on child dental health.
In this study in oral epidemiology, officially collected statistics are presented which show that, 15 yr after fluoridation commenced in Auckland, New Zealand, there was still a significant correlation between dental health of children and their social class. They also show that treatment levels have continued to decline in both fluoridated and unfluoridated areas, and are related to social class factors rather than to the presence or absence of water fluoridation. In the unfluoridated areas all the children, and in the fluoridated areas only selected children, had received regular topical fluoride treatments. In both areas the use of fluoride tooth-pastes and oral hygiene had been encouraged. When the socioeconomic variable is allowed for, child dental health appears to be better in the unfluoridated areas.
