Objective: To demonstrate a public-domain Cost Calculator (CC) that allows communities with limited data and analytical capabilities to project the cost-effectiveness of fluoridating the water in their community.

Methods: The CC uses methodologies recommended by the Panel on Cost-Effectiveness in Health and Medicine. Users may enter community-specific values for cost and effectiveness parameters (e.g. caries increment, cost of a restoration, and population age distribution) or accept default values obtained from national surveys and published studies specific to the size of the community and region where the community is located.

Results: The CC walks the user through calculation of the annual per person fluoridation cost, resulting averted treatment and productivity costs, and annual per person net cost (fluoridation costs less averted treatment and productivity costs). Finally, the CC projects the annual per person net cost to avert one cavity attributable to community water fluoridation (CWF). Users may vary the input or default parameter estimates to perform sensitivity analysis. Using default parameters the CC found CWF to be cost-saving in every region of the U.S.

Conclusions: In a time of declining public health resources it is important to demonstrate the cost-effectiveness of community based prevention. The CC helps community planners to generate concrete data to promote implementation of this cost effective public

Learning Objectives:
• Describe the information required to estimate cost effectiveness using the community water fluoridation (CWF) Cost Calculator. • Discuss how communities can use the CWF Cost Calculator projections to promote fluoridation. • Using the CWF Cost Calculator, analyze a real or hypothetical community’s cost effectiveness of implementing CWF.
