[Fissure sealing combined with enamel fluoridation. Follow-up study 2 year after sealing].

In a two-year study the adhesion of diluted composite material as fissure sealant was tested upon etched and etched-fluoridated (aminofluoride) occlusal surfaces of molars and premolars. After 24 months the sealant was found to be intact in 89.3% of the only etched and in 85.6% of the etched-fluoridated fissures. 3.9% of all sealed fissures showed either an increase in the degree of caries or a filling, while the control teeth showed a percentage of 49.7 DF. Fissure sealing therefore appears to be an adequate method for reducing occlusal caries.
