Abstract
A telephone survey was carried out in 1994, in the Quebec City region, among 1006 people living in two municipalities where tap water is fluoridated and 1003 people living in two municipalities where there is no fluoridation. Knowledge of the main benefit associated with the use of fluoride (prevention of tooth decay) in drinking water was not different in fluorated versus non- fluoridated municipalities (20.4% vs 19.4%, p = 0.57). Knowledge of its main disadvantage (increase of dental fluorosis) was very low and similar in both groups (3.1% vs 2.0%, p = 0.11). Opposition to fluoridation was slightly higher in fluoridated areas (22.0% vs 18.3%, p = 0.04), and the use of fluoridated supplements for children was much less important in fluoridated areas (4.4% vs 12.4%, p = 0.001). No changes in the measures of association (odds ratios) were found after adjustment for the different characteristics of the participants (age, family income, education). Opposition to fluoridation was lower among those who believed their tap water was fluoridated (even if not): 19.9% vs 34.5%, p < 0.001. This study demonstrates that there is still need for public health education on the uses of fluorides. Une enquête téléphonique a été menée en 1994, auprès d’un échantillon de personnes résidant dans la région de Québec: 1006 résidants dans deux municipalités avec fluoruration et 1003 personnes dans deux municipalités sans fluoruration. La connaissance du principale bénéfice associé à l’utilisation de fluorures dans l’eau potable (prévention de la carie dentaire) n’était pas différente dans les municipalités fluorées et non fluorées (20,4 vs 19,4 %; p = 0,57). La connaissance du principal désavantage (augmentation de la fluorose dentaire) était très faible et semblable dans les deux groupes (3,1 % vs 2,0 %; p = 0,11). Les mesures d’association considérées (rapports de cotes) n’étaient pas modifiées après ajustement pour les différentes caractéristiques des participants (âge, revenu familial, éducation). L’opposition à la fluoruration était plus faible chez ceux qui pensaient que leur eau était fluorée (même si elle ne l était pas): 19,9 % vs 34,5 %; p < 0,001. Cette étude démontre qu’une éducation sanitaire sur l’usage des fluorures est encore nécessaire.Keywords
