COMMENT: One sample in a far, far away place in Alaska while picturing an adult picture to imply adults involved in the study, we find out that it was adolescents only and only those that Medicaid dental care as opposed to out of pocket or other insurance options. One sample does not make a definitive result. Also, adolescent behaviors do change over time. On top of that, studies show that tooth paste with fluoride has not prevented as many cavities as they brag about. So, before declaring the results as a fluoride does prevent rotting teeth, how a bit better control study and multiple studies? Be careful of "oppositions of science falsely so called" (1 Timothy 6:20).
