Final answer:
Community water fluoridation is an ideal public health measure characterized by reducing dental caries, being safe and effective, and being cost-effective. The exception is the increase in mottled enamel cases.
Step-by-step explanation:
Community water fluoridation is an ideal public health measure characterized by all of the following EXCEPT mottled enamel cases. Community water fluoridation helps reduce dental caries, is safe and effective, and is a cost-effective method of delivering fluoride to all.
It has been shown to prevent tooth decay, strengthen enamel, and enhance remineralization of teeth. However, in areas with naturally high levels of fluoride in groundwater, both dental and skeletal fluorosis can occur.
