[Results of collective caries prevention by means of rinsing with a 0.2 percent sodium solution after 88 months].

In the framework of a governmental program in the Republic of Cuba, mouth rinsing actions with a 0.2% sodium fluoride solution were accomplished in more than 900,000 children at a 14-day rhythm. The caries-statistical investigations performed in groups of 400 6-13-year-old children each showed a significant caries reduction (40-50%). The cost-benefit ration can be regarded as positive.
