A new guide jointly produced by the British Fluoridation Society and the American Fluoridation Society, “How to Read a Study About Fluoride or Fluoridation,” can help dental and public health professionals strengthen their ability to assess water fluoridation research quality. The guide offers nine scientifically-based suggestions for assessing the quality of published research. The guide is accompanied by a “spoof research paper” that can be used to to apply these nine suggestions.
