Hipomineralização incisivo-molar em crianças

Abstract

Introdução: A Hipomineralização incisivo-molar (HIM) é uma patologia de origem sistémica caracterizada pela redução da mineralização de um a quatro primeiros molares permanentes, podendo também afetar os incisivos permanentes. Objetivo: A presente revisão da literatura tem como objetivo sistematizar o conhecimento existente sobre HIM, assumindo como foco de discussão central, a caracterização do quadro clínico e o padrão de distribuição das lesões observadas nas crianças com HIM. Metodologia: Realizou-se uma pesquisa bibliográfica nas bases de dados MEDLINE, PubMed, B-on, ScienceDirect, Elsevier e Google Académico, com as palavras-chave “molar incisor hypomineralization”, ”prevalence”, “amelogenesis”, “ etiology”, “clinical features”, “diagnosis”, “differential diagnosis” e “treatment” conjugadas com os conectores boleanos “AND” e “OR”. Os critérios de inclusão foram: artigos em inglês, espanhol e português, com data de publicação nos últimos 20 anos. Foram considerados relevantes 68 artigos. Na observação, foram observadas 18 crianças com idades compreendidas entre os 8 e os 14 anos de um total de 238 crianças rastreadas nas escolas. Como critérios de inclusão, foram incluídas crianças com idades compreendidas entre os 7 e os 16 anos, que apresentavam pelo menos um dos primeiros molares permanentes com HIM. Nos critérios de exclusão, foram consideradas não elegíveis, crianças com opacidades 2mm, FPE, sensibilidade dentária, restaurações atípicas, carie dentária e extrações devido a HIM. Resultados: Das 18 crianças observadas 7.6% tinham HIM. Dos 216 dentes observados, 25.9% tinham HIM ligeira, 17.1 % tinham HIM severa, 43.1% tinham opacidades >2mm, 6.9% tinham FPE, 15.7% tinham sensibilidade dentária, 8.3% tinham restaurações atípicas, 7.9% tinham carie dentária e 0.9% foram extraídos devido a HIM. Conclusão: A HIM é um defeito qualitativo do esmalte de etiologia desconhecida. A sua prevalência diverge de acordo com os critérios de diagnóstico e metodologia utilizada, pelo que são necessários mais estudos.

Introduction: Molar-incisor hypomineralization (MIH) is a pathology of systemic origin characterized by the reduction of mineralization from one to four first permanent molars, which often also affects permanent incisors. Objective: This literature review aims to systematize the existing knowledge about HIM, taking as a central discussion the characterization of the clinical picture and the pattern of distribution of lesions observed in children with MIH. Methodology: A bibliographic search was carried out in the Medline, PubMed, B-on, ScienceDirect, Elsevier and Academic Google databases, with the keywords “molar incisor hypomineralization”, ”prevalence”, “amelogenesis”, “etiology”, “clinical features”, “diagnosis”, “differential diagnosis” and “treatment” combined with the “AND” and “OR” boolean connectors. The inclusion criteria were: articles in English, Spanish and Portuguese, published in the last 20 years. 68 articles were considered relevant. In observation, 18 children aged between 8 and 14 were observed out of a total of 238 children screened in schools. As inclusion criteria, children aged between 7 and 16 years, who had at least one of the first permanent molars with MIH, were included. The exclusion criteria, children with opacities 2mm, FPE, tooth sensitivity, atypical restorations, tooth decay and extractions due to MIH were recorded. Results: Of the 18 children observed, 7.6% had MIH. Of the 216 teeth observed, 25.9% had mild MIH, 17.1% had severe MIH, 43.1% had opacities >2mm, 6.9% had FPE, 15.7% had tooth sensitivity, 8.3% had atypical restorations, 7.9% had dental caries and 0.9% were extracted due to MIH. Conclusion: MIH is a qualitative enamel defect of unknown etiology. Its prevalence differs according to the diagnostic criteria and methodology used, so further studies are needed.
