Re: A question of fluoride?2 October 2009 at 9:15am Last edited: 12 October 2009 8:01am Statements regarding the scientific controversy surrounding water fluoridation are generally regarded as artefacts of antifluoridationist activity, with actual scientific debate over water fluoridation being resolved decades ago. Almost all major dental and health organisations either support water fluoridation or have found no association between it and adverse health effects [20]. Nonetheless, propagating the idea of an ongoing scientific debate gives the illusion of scientific uncertainty and is a favoured tactic of water fluoridation opponents.. Interestingly this is exactly the same tactic used by creationists and intelligent design advocates against evolution. |

Re: A question of fluoride?2 October 2009 at 9:49am Last edited: 12 October 2009 8:01am Another extract from the article: The major public health implications of the spread of misinformation regarding water fluoridation on the Internet is that this information finds its way into local anti-fluoride campaign materials which are used to influence councils who ultimately are required to make decisions on water fluoridation implementation. The standard procedure for making council decisions on matters outside of the expertise of council members is to invite comment from representatives of different sides of the issue. Councillors are presented with conflicting information of which they are not qualified to judge, and under public pressure by a small number of committed activists, may decide to maintain the status quo which means to not introduce water fluoridation. Other councillors may decide to carry out their own research and may turn to the Internet which is the primary source of misinformation regarding the fluoridation of water. One councillor from Northern NSW has quipped that "It took five minutes of research to confirm my opinion about fluoride" [34]. |

Re: A question of fluoride?5 October 2009 at 4:09am Last edited: 12 October 2009 8:01am Under the guise of being objective you seem the most deceptive. Most countries which do not fluoridate have decreased cavities as fast and often faster show the WHO data very clearly which can be found on the internet also. The US health department and CDC mayb e by accidnet only report that the cause of cavity decreases was fluoridation not mentioning cause was never proven, just claimed.

Re: A question of fluoride?5 October 2009 at 8:25am Last edited: 12 October 2009 8:01am I note that the list of references included in the EPA unions includes Colquhoun whom we referred to earlier in the thread. It also includes the Chinese study which talks about hip fractures: I refer you to the article I posted selections from earlier, When public action undermines public health: a critical examination of antifluoridationist literature, in particular to the sections labelled "Fear Mongering" and "Misrepresentation of the truth. This last section actually deals with the Chinese study referred to by the EPA unions. Misrepresentation often takes place by omission. Connett [83,84], for example, has regularly cited a study from China [85] as finding a doubling of hip fractures when people consume water with 1.5 ppm fluoride and a tripling of fractures when consuming water of greater than 4.3 ppm fluoride. This is cited as evidence of the deleterious effect of water fluoridation on the bones. What Connett does not state is that the doubling of hip fractures at 1.5ppm is not statistically significant and that the authors' find a 'U' shaped relationship between the amount of fluoride in the water and fractures, with optimally fluoridated water actually conferring a protective effect on bone fractures. Yet, handpicked and misrepresentative information may find its way from the Internet to prominent pieces in national newspapers [86] with little regard for the truth |

Re: A question of fluoride?6 October 2009 at 2:45am Last edited: 12 October 2009 8:01am Am I asking too much to show just one researcher that can show a mechanism of ingested benefit. Even the CDC and ADA now admit(just not to the public) the primary benefit is topical. By the way none have shown a mechanism that this happens at 1ppm. The Uk Health did admit in Aug 2008 that toothpaste below 1000ppm had little measurable benefit below 1000ppm for young kids. Same for the Aussies about three months ago but they suggested 5000ppm would be much more effective byut with much greater dental fluoroisis. Featherstone JADA 2000shjows it about as well as any but FAN has the list of 20 plus.

Re: A question of fluoride?6 October 2009 at 5:55am Last edited: 12 October 2009 8:01am Am I asking too much to show just one researcher that can show a mechanism of ingested benefit. I refer you once again to the article I have been quoting from: Another example of downplaying the evidence of the effectiveness of water fluoridation is the argument that fluoridated water is not required to be ingested to be effective. Opponents of water fluoridation often present quotes by researchers saying that the primary effect of fluoride is topical (that is acting on the tooth surface) rather than systemic [59]. However, recent research in Australia by Singh and colleagues [74-76] has found that the pre-eruptive or systemic effect of fluoride in water supplies is at least as important in accounting for the caries preventive effect of consumption of fluoridated water as the post-eruptive or topical effect. It is common for opponents of water fluoridation to cling to old or out-of-date research while ignoring newer research that might cast doubt on their theories. Sometimes statistics and results from many decades ago are quoted to support their beliefs and statements. Singh KA, Spencer AJ, Armfield JM. Relative effects of pre- and posteruption water fluoride on caries experience of permanent first molars. J Public Health Dent. 2003;63:11–19. doi: 10.1111/j.1752-7325.2003.tb03469.x. [PubMed] Singh KA, Spencer AJ. Relative effects of pre- and post-eruption water fluoride on caries experience by surface type of permanent first molars. Community Dent Oral Epidemiol. 2004;32:435–446. doi: 10.1111/j.1600-0528.2004.00182.x. [PubMed] Singh KA, Spencer AJ, Brennan DS. Effects of water fluoride exposure at crown completion and maturation on caries of permanent first molars. Caries Res. 2007;41:34–42. doi: 10.1159/000096103. [PubMed] Fluoridation is nothing more them a smoke screen government uses to make it look like they care. Conspiracy Theory Alert! Besides which, the argument you use to justify that claim isn't even remotely relevant in New Zealand. |

Re: A question of fluoride?6 October 2009 at 6:39am Last edited: 12 October 2009 8:01am Incidently, I did look up the Warren Levy study you mention. The study concerns the overuse of fluoride and does not support removing it altogether. In fact, the most telling point is that most of the scientists involved in the study including Steven M Levy, the head of the team that conducted the study, support the continued use of fluoride in water. They do say that in areas where there is a good level of dental care that the case for fluoridation is not as strong as it once was. "Instead of just pushing for more fluoride, we need to find the right balance," Levy says. Scientific American, January 2008. Dont' you just love those peer reviewed studies appearing in peer review journals? |
