"if you want to say the study was wrong and amalgams are safe, i agree with the others in here, go get a mouthful. ... i don't believe in conspiracy. i call a duck a duck. the nhanes III survey was just fine. and, it did compare the amount of fillings. i have given you other studies and you have not read any of them."
I'm not saying the study was "wrong". I'm saying that you are misinterpreting the data. It DID find a correlation bewteen more amalgams and chronic disease. An ASSOCIATION does not infer causality nor risk. In other words, maybe the people in worse health had more amalgams because sicker people may have fewer available resources to get composites and instead opt for the cheaper amalgams. In other words, epidemiological studies do not comment on which came first....the amalgam or the disease.
As far as other studies, I have read some of them. They are ALL biased. Just kidding. The ones I have read tend to be designed without controls, and are not blinded. Many are unavailable....it doesn't help as much to post only the citation. Post the actual text (as I have done) and it is available for all of us to discuss. BTW, studies in support of amalgam have weaknesses also.....there is no "perfect" study.
