Objective: To determine the association between genetic factors and molar-incisor hypomineralisation (MIH) and/or hypomineralised second primary molars by means of a systematic review.

Design: A search was performed in Medline-PubMed, Scopus, Embase and Web of Science databases; manual search and search in gray literature were also performed. Selection of articles was performed independently by two researchers. A third examiner was involved in cases of disagreement. Data extraction was performed using an Excel® spreadsheet and independent analysis was performed for each outcome.

Results: Sixteen studies were included. There was an association between MIH and genetic variants related to amelogenesis, immune response, xenobiotic detoxification and other genes. Moreover, interactions between amelogenesis and immune response genes, and SNPs in the aquaporin gene and vitamin D receptors were associated with MIH. Greater agreement of MIH was found in pairs of monozygotic twins than dizygotic twins. The heritability of MIH was 20 %. Hypomineralised second primary molars was associated with SNPs in the hypoxia-related HIF-1 gene and methylation in genes related to amelogenesis.

Conclusion: With very low or low certainty of evidence, an association was observed between MIH and SNPs in genes associated with amelogenesis, immune response, xenobiotic detox and ion transport. Interactions between genes related to amelogenesis and immune response as well as aquaporin genes were associated to MIH. With very low certainty of evidence, hypomineralised second primary molars was associated to a hypoxia-related gene and to methylation in genes related to amelogenesis. Moreover, higher agreement of MIH in pairs of monozygotic twins than dizygotic twins was observed.

Knowledge, awareness and attitudes among a group of Turkish dental students regarding molar incisor hypomineralization: a cross-sectional study.

Background: Molar incisor hypomineralization (MIH) is estimated to affect more than 800 million people worldwide. The clinical management of MIH can be challenging. For dentists, to provide effective and high-quality dental care to people affected by MIH, it is essential that they improve their awareness, ability to describe the clinical situation, and knowledge of treatment modalities.

Objective: Success of resin infiltration for the masking of MIH-lesions remains difficult to predict, prompting suggestions to adjust the treatment protocol. This exploratory in vivo study aims to evaluate whether monitoring the resin infiltration process using transmitted light, compared to ambient light, enables a better estimation of when the infiltration process is completed, and to assess how the treatment success, i.e.

Prevalence and predictors of molar-incisor hypomineralization among Egyptian children: a cross-sectional study.

Eur Oral Res

September 2024

Department of Pediatric Dentistry and Dental Public Health, Faculty of Dentistry, Mansoura University, Mansoura, Egypt.

Article Synopsis
  • The study aimed to assess the prevalence of molar incisor hypomineralization (MIH) in Egyptian children and explore its correlation with age, sex, birth complications, and endogamous marriage.
  • Approximately 3000 children aged 8-12 were examined using EAPD criteria, revealing a MIH prevalence rate of 7.2%, with molars being more affected than incisors.
  • Results indicated higher MIH rates in boys and a significant link between MIH and factors like birth complications and endogamous marriages, emphasizing the need for increased dental check-ups for at-risk children.*

First permanent molars (FPM) are highly susceptible to decay before the age of 15. When they are severely affected, the decision between conservation and extraction arises, particularly considering the potential for the second permanent molar (SPM) to replace the FPM. This cohort study aimed to evaluate clinical practices regarding FPM pulp necrosis treatment in children aged eight to twelve in two hospital departments in the Paris region.
