Pourquoi croire des études bidons? Disons que l'on vous vante les incroyables propriétés de anti-rouille d'une cire pour les automobiles. Mais si vous appliquez trop de couches de cire, la couleur de la peinture se détériorre. Alors, vous persisterez à appliquer des couches de cire pour protéger votre auto de la rouille? Pourquoi dépenser des fortunes pour savoir le nombre exact, ou même approximatif, de couches avant que la décandence survienne? Dr. John Yiamouyiannis examined the raw data from a large study that was conducted by the National Institute for Dental Research (NIDR). He concluded that fluoride did not appear to have any decay preventing success, as there was little difference in the DMFT values (the mean number of decayed, missing or filled teeth) for approximately 40,000 children. It did not matter whether they grew up in fluoridated, non-fluoridated or partially fluoridated communities. (Yiamouyiannis, J.A. "Water Fluoridation and Tooth Decay: Results from the 1986-87 National Survey of U.S. Schoolchildren", Fluoride, 23, 55-67, 1990). |

(Colquhoun, J. "Child Dental Health Differences in New Zealand", Community Healthy Services, XI 85-90, 1987). |
