Molar‐incisor hypomineralization in quilombola children and adolescents: A study of prevalence and associated factors

Abstract

Objectives: This cross-sectional observational study determined the prevalence and factors associated with molar-incisive hypomineralization (MIH) in quilombola children and adolescents in north-eastern Brazil. Methods: The sample consisted of 251 children and adolescents (8 to 14 years old) living in the rural quilombola community Lagoas in São Raimundo Nonato, Piauí (census population). Sociodemographic and health-related data were collected from pre-, peri-and post-natal health records and a clinical examination for MIH diagnosis was performed by four previously trained and calibrated examiners. Descriptive data analysis and Poisson regression were performed. The magnitude of the association was determined by adjusted prevalence ratio (PR) and confidence intervals (95% CI). Results: The prevalence of MIH was 46.6%. The presence of MIH was associated with gestational diabetes (PR = 2.49, 95% CI 2.08−2.99; p <0.001) and acute foetal distress (PR = 1.39; 95% CI 1.04−1.86; p = 0.025). Conclusion:It was concluded that the prevalence of MIH in the quilombola community was high and associated with gestational diabetes and acute foetal distress.

Molar incisor hypomineralization (MIH): prevalence and degree of severity in a Mexican pediatric population living in an endemic fluorosis area

“…As a consequence, there is a predisposition to significant retention of dental biofilm, tooth brushing difficulties, and a rapid caries progression 11 . Historically, this disorder is also known as “cheese teeth,” “hypomineralized” or “dysmineralized” permanent first molars, “idiopathic enamel hypomineralization,” and “nonfluoride hypomineralization.” 7,12 MIH is relatively frequent in many pediatric populations worldwide, exhibiting a very wide prevalence rate, ranging from 2.4 to over 40 percent 2,4‐6,8,10‐36 …”

“…2,[4][5][6]8, Most of the prevalence studies have been carried out in European and Asian countries; however, there have been several recent reports on this clinical topic in Latin American countries. For instance, Mexico, 11,[25][26][27]34 Brazil, 6,10,35,36 Chile, 13 Argentina/Uruguay, 16 and Colombia 23 ; the determined prevalence rates from these studies varied between 11.2 and 42.4 percent. Specifically, five studies have been conducted in México in well-definite and limited geographic zones, on school children from Mexico City and Naucalpan (Estado de México).…”

The Journey of SCAPs (Stem Cells from Apical Papilla), from Their Native Tissue to Grafting: Impact of Oxygen Concentration

“…It will be very interesting to characterize expression of these proteins in cultured SCAPs and to determine whether oxygen concentration regulates the formation of active podosomes towards migration purposes. Also, the present detailed cartography of healthy apical papilla tissue could help to determine whether the structure of this tissue or of dental pulp tissue is altered in pathologies like Molar Incisor Hypomineralization (MIH), a serious health problem which is increasing for still unknown reasons among teenagers [ 61 , 62 , 63 ].…”

Construção e análise das propriedades psicométricas de um questionário para avaliar o impacto da hipomineralização molar-incisivo na qualidade de vida relacionada à saúde bucal em crianças

“…com 20,4% e Dantas-Neta et al (2016) com 18,9%. Uma prevalência alta de 46,6% foi encontrada em crianças de uma comunidade quilombola, associada com histórico materno de diabetes gestacional e sofrimento fetal agudo (Dourado et al, 2021). Os autores sugerem mais estudos, inclusive em outras comunidades parecidas, atentando-se para o número elevado que esse tipo de defeito de desenvolvimento de esmalte pode apresentar algumas regiões do Brasil.…”

“…No Brasil, estudos epidemiológicos relatam que a prevalência de HMI varia de 2,5% a 46,6% da Costa Silva et al, 2010;Jeremias et al, 2013;de Lima et al, 2015;Hanan et al, 2015;Silva Júnior et al, 2015;Tourino et al, 2016;da Costa Silva et al, 2017;Dourado et al, 2021), com uma média nacional descrita em um estudo com metanálise de 13,4% , muito próxima à média mundial .…”
