Cost aspects of salt fluoridation.
The cost of salt fluoridation in a given country depends primarily on the number of salt factories and on the technical level available in the country. Equipment required may cost U.S. dollars 400,000 for large plants producing at least 20,000 tons/year providing salt for populations of several millions.

متن کاملFluoridation cessation: More science from Alberta
As with many large-scale research projects, we had more information than was possible to include in a single paper. We thus prepared multiple papers addressing different aspects of the study: overall trends in dental caries—tooth-level data and tooth surface-level data; and trends by socioeconomic indicators (Neurath et al [“the authors”] erroneously state that we “control” for these in the lat...
