[The use of fluorine-containing coatings for isolating fissures of the molars and premolars to prevent caries].

Experimental and clinical investigations were performed to assess the caries-preventing potencies of hermetic covering with Epoxylite-9075 (USA) and vitacryl (USSR) insulating the intact fissures in molars and premolars. Intact sheathing is capable of protecting the tooth against caries for a long time. Fluoride as a component of the material increased the enamel caries-resistance.
