Abstract:

Molar incisor hypomineralisation (MIH) is a common developmental condition resulting in enamel defects in first permanent molars and permanent incisors. Its prevalance varies between 2.8% and 44%. The etiology of MIH has not been fully clarified; however it is supposed that environmental and systemic conditions may be possible reasons for this condition. Hypomineralized molars exhibit proneness to caries, and severe restorative problems are often associated with such teeth. Incisors also present demarcated enamel opacities, although enamel breakdown is uncommon. The treatment of MIH depends on the severity of the enamel defect. A six step approach to management has been suggested, comprising: risk identification, early diagnosis, remineralization and desensitization, prevention of caries and post-eruption breakdown, restoration and extraction and maintenance of oral hygiene and oral care. The purpose of this review was to inform the reader on the diagnosis and treatment of MIH.
