Durham Citizens,

The Williams water  treatment plant that supplies the city of Durham with your tap water spends over $100,000 of YOUR money adding an admitted dangerous substance to the drinking water.  Ironically, the city of Durham’s own Duke University in cooperation with Professor Brian A. Burt conducted a study when this writer was living in Durham at the age of 4-5 years.   The study involved the city turning off public water fluoridation for a period of 11 months during 1990-1991, whilst observing the incisor changes in over 1800 K-5 aged children in Durham, NC.  The study concluded no increase in dental cavities (the very claimed benefit of fluoridation), but a decrease in fluorosis – the Center for Disease Control’s admitted malady to fluoridating public water supplies.

ABSTRACT

Durham, NC, fluoridated since 1962, had an 11-month cessation of fluoridation between September, 1990, and August, 1991. The purpose of this study was to assess the effects of this break on the development of caries and fluorosis in children. Study participants were continuously-resident children in Kindergarten through Grade 5 in Durham’s elementary schools. There were 1696 children, 81.4% of those eligible, for whom a questionnaire was completed and clinical data recorded. Age cohorts were defined by a child’s age at the time that fluoridation ceased. Caries was recorded in children in the Birth Cohort through Cohort 3, and fluorosis for children in Cohorts 1 through 5. Caries was assessed in the primary first and second molars according to the decayed-filled index; fluorosis on the labial surfaces of the upper permanent central and lateral incisors was assessed by the Thylstrup-Fejerskov (TF) index. Mother’s education was associated with caries; higher education of the mother had an odds ratio of 0.53 (95% CI 0.40, 0.76) for caries in the child. No cohort effects could be discerned for caries. Overall prevalence of fluorosis was 44%. Prevalence in Cohorts 1, 2, 3, 4, and 5 was 39.8%, 32.3%, 33.0%, 62.3%, and 57.1%, respectively. These cohort differences remained statistically significant in regression analysis. It was concluded that while the break had little effect on caries, dental fluorosis is sensitive to even small changes in fluoride exposure from drinking water, and this sensitivity is greater at 1 to 3 years of age than at 4 or 5 years.

This incredible hipocrisy and public health danger should be stopped as soon as possible!  Spread the video and the study to all mindful citizens!

    I think city municapalities do become rather complacent once a practice is started such as fluoridation of drinking water. Even though data may have found the practice acceptable in the sixties, one would hope that newer research/data would bring about modifications in practices such as this. Thank you for an insightful article.
