MIH: A Genetic Disorder

Decent Essays

MIH is a common developmental condition that results in enamel defects in first permanent molars and permanent incisors. It presents at eruption of these teeth. One to four molars, and often also the incisors, could be affected. This term was first introduced in 2001 by Weerheim to describe the condition. Prior to introduction of this term, many names were used to describe it, like idiopathic enamel hypomineralization, non-fluoride hypomineralization, cheese molars and etc.
MIH is a qualitative effect of enamel and there is no enamel thickness loss. Any reduction in enamel thickness seen clinically is as a result of post eruptive enamel breakdown. The Asymmetrical occurrence of MIH molars and incisors within individuals suggests that ameloblasts …show more content…

Fluorosis, Enamel hypoplasia and Amelogenesis Imperfecta hypocalcified type may be confused with MIH. Fluorosis is a diffused opacity and is not well demarcated like MIH and other teeth can be involved. Also teeth affected by Fluorosis are caries resistant. Enamel Hypoplasia is a quantitative defect of enamel which causes reduced thickness of enamel and it’s result of disruption of emeloblasts during secretory phase of amelogenesis. MIH and enamel hypoplasia can be difficult to differentiate when they have post eruptive enamel breakdown. Amelogenesis imperfecta is a genetic condition in which all or most of teeth are …show more content…

Complexity of treatment, multiple interventions and limitations of materials available in market also pose a challenge for the treating clinicians. Many studies and authors have referred to MIH as a public health problem and the focus should be more on in depth understanding of etiology and prevention. Identification and understanding of new genes and proteins such as amelotin and apin during the maturation stage of amelogeneis can possibly help to treat MIH in future. Meanwhile, treatment plan for teeth affected with this condition should aim to provide durable restorations in a pain and anxiety free environment for the
