What are the Epidemiological Methods Used to Study Water Fluoridation?
Epidemiologists use various methods to study the effects of water fluoridation. Ecological studies compare caries rates between fluoridated and non-fluoridated communities. Cohort studies and case-control studies can provide more detailed information on individual exposure and outcomes. Randomized controlled trials (RCTs) are less common due to ethical considerations but can offer high-quality evidence when feasible.
