Another look at Brunelle & Carlos
Recently we received a letter commenting on our analysis of the Brunelle & Carlos (1990) paper. Before we print the letter and Michael’s response, a little background. The Brunelle & Carlos paper was published in the Journal of Dental Research, Volume 69, pages 723-727, in 1990. The paper was the official analysis of the data […]
More Discussion on Brunelle & Carlos
We have received several responses to IFIN #290 on the very meager benefits demonstrated in the largest survey ever conducted on tooth decay in the US (Brunelle and Carlos, 1990). 1) Cory Mermer points out that 0.6 tooth surfaces out of 128 is actually less than 0.5% not just “less than 1%” as we more […]
Recent Trends in Dental Caries in U.S. Children and the Effect of Water Fluoridation
This study presents the DMFS results of the National Institute of Dental Research’s 1986-87 national survey of tooth decay in the United States. Among 5-17 year old children, it found an average difference of 0.6 DMFS between children living in fluoridated vs. unfluoridated areas. Although the authors don’t mention it, 0.6 DMFS represents less than 1% of the number tooth surfaces in a child’s mouth.

An analysis of national survey data collected by the National Institute of Dental Research (NIDR) concludes that children who live in areas of the U.S. where the water supplies are fluoridated have tooth decay rates nearly identical with those who live in nonfluoridated areas.
