Molar-Incisor-Hypomineralisation: A literature review

Abstract

It is important that children with MIH are diagnosed as early as possible and managed appropriately; this will involve multidisciplinary input.

Molar Incisor Hypomineralization in Monozygotic Twins: A Case Report

“…In addition, the sensitivity may lead to the avoidance of brushing in the area, which can hasten the post eruptive enamel breakdown. 3,8 The management of MIH is thus very challenging and depends on various factors such as the extent and severity of the lesion, presence of sensitivity, post eruptive enamel breakdown, the patient's age and cooperation level and the child and parental expectations. Clinical approaches may vary accordingly, from simple preventive measures such as resin or glass ionomer sealants to more invasive approaches such as extraction in association with orthodontic management.…”

“…A multidisciplinary approach is therefore mandatory. 3,8,13 In a study conducted by Jalevik et al 17 on Swedish children, it was found that by the age of 9, children with MIH-affected FPMs had undergone dental treatment nearly ten times more frequently than the controls undergone by healthy children, who were the controls, and the affected teeth had each been treated twice, on an average. This underscores the importance of maintaining good oral hygiene and other preventive measures which may help in the prevention of dental caries and post eruptive breakdown.…”

“…These teeth do however require regular follow up to monitor the retention of the sealants. 3 A study by Lygidakis 10 has shown that application of a 5 th generation bonding agent prior to sealant placement improves its retention. Glass ionomer sealants are recommended for partially erupted molars or when adequate control of moisture is not possible, but are shown to have very poor retention rates.…”

“…8,13 In mild MIH-affected molars with small carious lesions involving 1 to 2 surfaces, composite resins are the restorations of choice and in carious teeth involving 2 or more surfaces with increased or spontaneous sensitivity, full coronal coverage with prefabricated stainless steel crowns is the preferred treatment option. 3,8,13 Composite restorations bonded with a self etching primer adhesive are shown to be successful in mildly affected MIH lesions. 12 In some cases of teeth with severe MIH where the teeth are non restorable and have a poor prognosis, extraction may be the only option.…”

“…It is strongly believed that these factors act synergistically since none of them has a definite causative relation to the condition. 3,4,5 The prevalence of MIH has been studied extensively and it varies greatly from 2.4% in Germany and Bulgaria to 40.2% in Brazil. 6 The condition shows no gender predilection and the maxillary teeth, most specifically the molars, are most commonly affected.…”
