“…Some authors have suggested MIH to be an autosomal recessive condition or localized amelogenesis imperfecta with possible association with genes related to enamel formation such as AMBN, TUFT1, and TFIP11. [ 19 ] MIH may be acquired as a result of prenatal, perinatal, and postnatal illness; low birth weight; antibiotic consumption; and toxins from breastfeeding. [ 1 11 ] Certain drugs such as chemotherapeutic, antibiotics, asthma, and antiepileptic drugs can cause MIH.…”

Background:Molar incisor hypomineralization (MIH) is the hypomineralization of systemic origin of one to four permanent first molars, frequently associated with affected incisors. It is presented as demarcated enamel opacities of different colors, occasionally undergoing posteruptive breakdown. The characteristic feature of MIH is the clear demarcation between the affected and sound enamel. There is asymmetry of defects present in the molars and incisors where one molar or incisor can be severely affected, while the contralateral tooth may be clinically sound or have only minor defects.Aim and Objective:The aim of this study is to evaluate schoolchildren of 7–12 years of age with at least one of the first permanent molars fully or partially erupted from randomly selected government and private schools in Chennai using the European Academy of Pediatric Dentistry (EAPD) criteria for MIH, to determine the prevalence and characteristics of MIH.Materials and Methods:The dental examinations were performed in the classroom using a mouth mirror and explorer under a headlight. Teeth were wiped with gauze when necessary to remove plaque or the food accumulations. Surfaces that were examined were the buccal, lingual, palatal, and occlusal surfaces of permanent first molars and labial surfaces of upper and lower incisors. A single examiner was involved to avoid interexaminer bias. All the data were collected and scored using the EAPD criteria for MIH.Results:A total of 22 (12.9%) children out of the examined 170 had MIH.Conclusion:Distribution of MIH was more in males, more in 9 years of age. A total of 13 children had first molars affected and 9 children had both incisors and molars affected. Molars were affected more than the incisors. Mandible was affected more in comparison with the maxilla. Right side was affected more than the left side. The distribution of MIH was more in government schools compared to private schools.

“…Clinical management of MIH is difficult due to the rapid development of dental caries, limited cooperation of children, and repeated breakdown of restorations [ 11 ]. MIH can affect both aesthetics and cariogenic susceptibility and is considered a global dental problem [ 12 ].…”

Molar incisor hypomineralization (MIH) is defined as hypomineralization of systemic origin of one to four first permanent molars, and incisors are also frequently affected. This disorder is a serious concern in pediatric dentistry. Teeth affected by MIH have many dental problems, such as hypersensitivity, poor aesthetics, and rapid progression of dental caries. The prevalence of MIH ranges from 2.8% to 21% among studies with more than 1000 subjects in different countries and age groups. The etiology of MIH is unclear, but genetic and environmental factors have been proposed. This review describes the prevalence, etiology, and clinical management of MIH. A detailed description of MIH prevalence in Japan is also provided.

“…These enamel defects tend to fracture during eruption and cause not only dentin hypersensitivity but also increased susceptibility to caries. [5] Therefore, given the burden of disease and high prevalence of MIH in some populations, [6][7] the cost of these conditions to the affected families as well as the general community can be substantial.…”

“…[8] In addition, while MIH diagnosis is reported by some studies based on the presence of at least one affected first permanent molar (FPM), other studies have based the diagnosis on affected anterior teeth when an affected FPM was not present. [6] The presence of hypomineralization in other teeth including the second primary molars, cusp tips of second permanent molar and canines have been reported. [5] Furthermore, evidence from several studies and systematic reviews indicate hypomineralized second primary molars are highly predictive of MIH with a 33% increase in incidence of MIH if an affected primary tooth is diagnosed.…”

“…[9][10][11] Consequently, a number of studies have adopted other terminologies and suggest that incisor hypomineralization (IH), molar hypomineralization (MH) or deciduous molar incisor hypomineralization (DMH) terms which take into account all the other affected teeth should be included as part of the MIH spectrum. [6,12] In addition, there is inconsistency in applying diagnostic criteria that quantifies MIH enamel defects. While some studies report using EAPD system, others have applied modified criteria to include severity level of MIH or developed their own diagnostic criteria to account for extent of the defect.…”

Background: Molar Incisor Hypomineralization (MIH) is considered a highly prevalent clinical problem worldwide. The etiology of MIH involves a complex interaction between systemic and environmental insults with possible genetic contribution. Early diagnosis is facilitated by collaboration between clinicians responsible for oral health management of the patient and is the key for enhancing the long-term prognosis and quality of life of affected children. MIH management is a formidable oral health challenge due to the wide spectrum of clinical presentation with the need for tailored treatment for the child affected by MIH condition. Objective: To provide dental practitioners with an updated and evidence-based overview of MIH etiology, diagnosis, and treatments modalities available for its management. Conclusion: In this review, recent clinical evidence on MIH etiology, diagnosis and treatment is presented. Given recent availability of sophisticated technologies there is an increasing number of treatment modalities now at the fingertips of all oral health clinicians alike, ranging from preventive measures, management of hypersensitivity to advanced restorative techniques. The tailored treatment plan should encompass a short and long-term approach requiring more frequent dental check-ups in order to achieve better outcomes and prognosis. Future translational clinical research to best practice that will enhance our understanding of the exact causes of MIH and allow development of standardized diagnostic criteria as well as optimal treatment strategies are warranted.
