Compared to the situation in Japan, the USA or Great Britain fissure sealing for caries prevention seems to be less popular in Switzerland. Each Swiss dentist used per year (i.e. statistical average in 1988) sealants for an amount of sfr 40.00 compared to e.g. sfr 50.00 in the USA or sfr 55.00 in Japan. The explanation may be found in the high efforts and positive results already achieved in Switzerland with other preventive measurements such as tooth cleaning and various forms of fluoridation. The three most popular brands used for fissure sealing in Switzerland in 1988 and 1989 are: Delton (market share 66% by value, 50% by weight); Helioseal (10% by value, 20% by weight); White Sealant (20% by value, 18% by weight).
