Molaren Inzisiven Hypomineralisation und Milchmolaren Hypomineralisation - klinisches Erscheinungsbild, Prävalenz und deren Ursachen - Molar Incisor Hypomineralisation and Deciduous Molar Hypomineralisation - clinical appearance, prevalence and determinants for its occurrence

Abstract

Background: Molar Incisor Hypomineralisation (MIH) and Deciduous Molar Hypomineralisation (DMH) are frequently occurring dental problems in children. Children with MIH have demarcated opacities in their erupting first permanent molars often in combination with demarcated opacities in their permanent incisors. Children with DMH have comparable demarcated opacities in their second primary molars. The hypomineralised enamel contains less mineral, often resulting in an easy post eruptive enamel loss with rapid caries progression. Results: The prevalence of MIH and DMH varies between birth-years and countries and even between cities. The most recent prevalence of MIH in Germany is 9.9 %, the prevalence of DMH has not been described yet in Germany. The aetiology of MIH and DMH is still unclear. Many possible determinants have been described in literature. The determinants for DMH can be found earlier in life than the determinants for MIH, but they show overlap. This can be related to the dental development. Children with DMH have an increased risk of having MIH. Conclusion: Early diagnosis of DMH and MIH is important, so extra attention can be paid to these children by dentists and their team in the period of eruption of the second primary molars and first permanent molars
