Acceptability of Fluoride Use in Finnish Municipalities

The aim of this study was, firstly, to determine what methods of delivering fluorides might be acceptable to Finnish municipalities and, secondly, to investigate which characeristics of the municipalities best explain the variation in acceptability of fluorides. A sample, composed of 46 Finnish municipalities and representing the communes according to number of inhabitants was drawn and a mail survey sent to decision-makers (n=1922). In this survey we assessed the characteristics of each commune and its decision-makers and asked how acceptable various methods of fluoride delivery were. The acceptability of the various methods was: toothpaste 95%, gels and varnishes 81%, rinses 63%, salt 48%, piped water 33%, and milk 11%. In industrialized communes these methods of delivery were usually slightly better accepted than in nonindustrialized areas. Acceptability of fluorides seemed to differ in the various regions of Finland, Uusimaa region being the most liberal towards use of fluorides. Members of the labour parties seemed to accept piped water containing fluoride and fluoridated milk significantly more often than did conservatives. Among decision-makers, the various methods of delivery were best accepted by dentists, physicians and members of health councils.
