The status of fluoride mouthrinse programmes in Japan: a national survey

The purpose of this investigation was to determine the current status of fluoride mouthrinse programmes throughout Japan. Data collection and analysis took place in 1992. The focus of this study was on schools that were participating in the rinse programme at the time of the survey. Questionnaires were sent by mail to 49 dentist-members of the Association for the Promotion of Fluoride Use in Japan. These members gathered information from the schools and, when necessary, also from local government offices. Starting with a single prefecture in 1970, the rinse programme increased to 32 out of 47 prefectures by 1992. The total number of schools using fluoride mouthrinse was 1,183 (nursery schools and kindergartens 48 per cent, primary schools 46 per cent, and secondary schools 6 per cent). In nursery schools and kindergartens, 60 per cent of the participating schools adopted the daily method using 0.05 per cent NaF solution. In primary and secondary schools, 78 per cent adopted the weekly method using 0.2 per cent NaF solution. The costs for the rinse regimen were paid for by public funds of the prefectural and municipal governments in 71 per cent of the schools. Fifty-four per cent of the schools which first initiated the rinse programmes in their districts identified dentists and dental associations as the most influential in programme acceptance and implementation. Although the number of fluoride rinse programmes is increasing, it is still modest. These results suggest that cooperation between dental organisations, dental schools and prefectural governments can play very important roles in implementing school based rinse programmes.
