Question



  1. What is the effectiveness of community water fluoridation (fluoride level between 0.4 ppm and 1.5 ppm) compared with non-fluoridated drinking water (fluoride level < 0.4 ppm) in the prevention of dental caries in children and adults?




  2. What are the effects of community water fluoridation cessation (fluoride level < 0.4 ppm) on dental caries in children and adults compared with continued community water fluoridation (fluoride level between 0.4 ppm and 1.5 ppm), the period before cessation of water fluoridation (fluoride level between 0.4 ppm and 1.5 ppm), or nonfluorinated communities (fluoride level < 0.4 ppm)?




  3. What are the negative effects of community water fluoridation (at a given fluoride level) compared with non-fluoridated drinking water (fluoride level < 0.4 ppm) or fluoridation at different levels on human health outcomes?




Key Message

Five non-randomized studies were identified regarding the clinical effectiveness of community water fluoridation in the prevention of dental caries and the negative effects of community water fluoridation on human health outcomes. No relevant studies were identified regarding the effects of community water fluoridation cessation on dental caries.
