The Halo Effect: Quantifying the diffused benefit from water fluoridation in the United States
Griffin SO, Gooch BF, Lockwood SA, Tomar SL. Community Dent Oral Epidemiol 2001;29:120–129.
Demonstrates the total contribution of water fluoridation, not just to fluoridated communities but to surrounding nonfluoridated communities as well. This article helps to:

  • Explain the reason for the decrease in measurable effectiveness of fluoridation efforts over time.
  • Explain that rates of dental disease between fluoridated and nonfluoridated communities underestimate the effectiveness of community water fluoridation because nonfluoridated communities are receiving benefits from neighboring fluoridated communities.
  • Quantify the diffused benefit of community water fluoridation.
  • Explain increases in dental decay if fluoridation is discontinued by taking into account the diffusion effect.
