Since 1950, the investigations of Cox, Dean and Armstrong Iead to conclude that fluoride increased the resistance to dental caries but produced fluorosis in high concentrations (over 1 ppm ). Nowadays, in spite of the varied lines of research based in caries prevention methods, none of them has overcome Fluoride as a cheap, inoffensive and efficient method for this purpose. A review about FIuoride as an Early Childhood Dental Caries preventive method is presented, focused in fluoride varnishes. We also show the scheme of Fluoride application.
