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.

The difficulty for lhe diagnosis of carieo lessions in temporal teelh has made lhis work improve in a closer diagnosis using the F1uorescence of!he Laser. As we know lhe most sensitive part for caries is the Oclusal surface, because of !he characleristic morphology lhat this piece presents, make lhe micro organisms and rest oí íoad to stay. Normally !he caries diagnosis on !he oclusal surface is determinated by a combination of different techniques lhat includes lhe intra oral exam wilh lhe use of an explorer and radiographies. The purpose oí lhis research is to determinate lhe efficiency oí lhe Visual and radiographics exam in lhe diagnosis oí incipient caries lesion and compare lhem wilh lhe results found wilh lhe fluorescence laser technique.
