The increase of the enamel hipomineralizarion prevalence worries pediatric dentistry. It goes from delimited yellowish whited opacities to the rupture of the enamel, always related to the permanent first molars and incisives. It is because this reason that this patology is redefined as "Molar Incisor Hipomineralization", what motives the international use of the term MIH. This is about a hipomineralization enamel lesion, of sistemic origin and complex ethiology which is developed on the first year of the patient’s life. The diagnosys must be done whith different enamel hypoplasia, fluorosis and imperfect amelogenesis This has a significant impact in the treatment necesities even in comunities whith low caries activity which make difficult the adhesive techniques and require expensive rehabilitation processes in adults. It’s prevalence varies between 3 and 23.4% and both sexes are affected equally. In our country studies are needed to determine it’s prevalence.
