Introduction: Dental enamel is an uncommon tissue in body .Once it is formed, it is not remodeled, unlike other hard tissues such as bone. Because of its non- remodeling nature, alterations of enamel during its formation permanent damage of the enamel is Molar Incisor Hypo-mineralization (MIH) Methods and results: it can be said that the prevalence of MIH appears to be increasing, and managing affected children is a general problem for pediatric dentists. The etiology is unclear and may be multifactorial, in fact the children born preterm and in their first 3 years with poor general health or systemic conditions may develop MIH. The early identification of such children may permit monitoring of their PFMs so that remineralization and preventive measures can be considered as soon as affected surfaces are visible in oral cavity. In order to provide the complex care, it must address the child's behavior and anxiety, seeking to provide durable and pain-free restorations. It is recommended that it is necessary to consider further research to clarify etiological factors and improve the durability of restorations in affected teeth Key words: MIH, Enamel, PFM, Hypo-mineralization.
