A recent Cochrane review on water fluoridation found that the initiation of water fluoridation resulted in reductions in dmft of 1.81 (35%) and in DMFT of 1.16 (26%).

However, the majority of the studies were conducted prior to 1975, and the widespread use of fluoride toothp...

Thus, the law does not consider that both caries and fluorosis are dependent on the dosage and duration of fluoride exposure because they are both ...

OBJECTIVES The aim of this study was to evaluate the systemic effect of water fluoridation on dental caries prevalence and experience in Cheongju, South Korea, where water fluoridation ceased 7 years previously. METHODS A cross-sectional survey was employed at two schools where water fluoridation had ceased (WF-ceased area) and at two schools where the water had never been fluoridated (non-WF...

The city of Araçatuba, in the Northwest region of the São Paulo state, Brazil, started public water supply fluoridation in 1972 and, based on the average annual highest temperature, has kept the ...
