Molar Incisor Hypomineralisation - Overview, Clinical Aspects, Treatment Recommendations

Molar incisor hypomineralisation (MIH) is an enamel developmental defect with a currently indistinct etiology. Affected teeth primarily are first permanent molars and/or first permanent incisors. In the first dentition second molars may show the typical structures of molar - incisor hypomineralisation as well. Therapy planning and in many cases restaurative therapy itself is complicated by the occurence of different intra - individual grades of MIH as well as by an ineffectiveness of local anesthetics, that often comes along with dental hypersensitivities caused by MIH. In order to make a good decision of treatment for the young patients, close cooperation and communication between restorative dentistry and orthodontics is essential. This article on the one hand lights up aspects concerning the etiology of molar - incisor hypomineralisation and deals with clinical, diagnostic and therapeutic matters. On the other hand this overview is supposed to serve as an assistance concerning sufficient therapy planning following interdisciplinary decision - making.
