Molar incisor hypomineralization in pediatric dentistry: general considerations

Abstract

Introduction: Molar incisor hypomineralization (MIH) encompasses the hypomineralization of the enamel that afflicts one or more first permanent molars and may also affect permanent incisors. Second premolars and permanent canines may also be involved, as well as some deciduous ones, among which the second molars are mentioned. Objective: The aim of the present article was to investigate the clinical manifestations caused by molar incisor hypomineralization under the pediatric dentistry approach. Method: A bibliographic review study was carried out with search in the databases LILACS and Google Scholar. In the LILACS database, the search expression was used: molar incisor hypomineralization and pediatric dentistry. In the Google Scholar database we used the search term: molar incisor hypomineralization and pediatric dentistry. Results: It is important to carry out the early and correct diagnosis of MIH, based on detailed anamnesis, which is capable of investigating the existence of possible diseases in the period of childhood and proceeding concomitantly to the clinical examination form to establish an adequate prognosis. Conclusions: It was concluded that the early diagnosis of MIH, established immediately and concomitantly at the time of dental eruption and that a preventive approach avoids the accomplishment of treatments with greater complexity and is capable of minimizing any damages, arising from some clinical manifestations of MIH that may occur, such as: dental caries; wear of dental tissue; loss of enamel and tooth sensitivity, among others.
