"Junk science is opinion that gets quoted from press release and letters to the editor, or half-truths cherry-picked out of context from scientific articles." The simplest way to dispel with all the "junk science" ? Produce the factual evidence that the National Sanitation Foundation International requires to approve fluoridation chemicals. The ANSI/NSF Standard 60 will prove the safety of fluorosilicic acid with the following: , toxicity data to be considered shall include but not be limited to, assays of genetic toxicity, acute toxicity …, short term toxicity …, subchronic toxicity …, reproductive toxicity, developmental toxicity, immunotoxicity, neurotoxicity, chronic toxicity (including carcinogenicity), and human data (clinical, epidemiological, or occupational) when available. To more fully understand the toxic potential of the substance, supplemental studies shall be reviewed, including, but not limited to, mode or mechanism of action, pharmacokinetics, pharmacodynamics, sensitization, endocrine disruption, and other endpoints, as well as studies using routes of exposure other than ingestion. Structure activity relationships, physical and chemical properties, and any other chemical specific information relevant to the risk assessment shall also be reviewed. … A weight-of-evidence approach shall be employed in evaluating the results of the available toxicity data. This approach shall include considering the likelihood of hazard to human health and the conditions under which such hazard may be expressed. A minimum data set consisting of a gene mutation assay, chromosomal aberration assay, and a subchronic toxicity study shall be required for the performance of a quantitative risk assessment. So lets quit quibbling, publish the studies in this paper so that everyone can see for themselves that fluoride is "safe and effective". View Comment

I agree with dentist Carl Tegtmeier. "Junk science is opinion that gets quoted from press release and letters to the editor, or half-truths cherry-picked out of context from scientific articles."
