Abstract(s)
Hipomineralização molar-incisivo (MIH) é um defeito estrutural do esmalte. Os dentes afetados apresentam opacidades isoladas, assimétricas em dentes homólogos, manchas de cor branca, amarelo ou castanha, consoante a severidade da lesão afetando como o nome sugere, os primeiros molares e incisivos da dentição permanente.
A exigência estética dos pacientes é cada vez mais importante, pois as manchas coloridas do esmalte podem, dependendo de sua localização e gravidade, ter um grande impacto estético no sorriso dos nossos pacientes e prejudicar muito a sua vida social.
Atualmente existem soluções simples e minimamente invasivas para lidar com estas situações, sendo uma das opções de tratamento muito utilizada, a técnica de resina infiltrativa ICON®, sendo a sua ação baseada na erosão da superfície da lesão através da utilização de um ácido e na subsequente infiltração de uma resina de baixa viscosidade.
A realização desta revisão narrativa tem como principal objetivo relembrar os fatores etiológicos, diagnóstico, características clínicas e tratamento de lesões de hipomineralização molar-incisivo, assim como, demonstrar a eficácia da técnica do ICON® na remoção destas lesões.
Molar-incisor hypomineralization (MIH) is a structural defect of the enamel. Affected teeth present isolated opacities, asymmetric in homologous teeth, white, yellow or brown stains, depending on the severity of the lesion, affecting, as the name suggests, the first molars and incisors of the permanent dentition. The esthetic demands of patients are increasingly important, as the colored stains on the enamel can, depending on their location and severity, have a great aesthetic impact on our patients' smiles and greatly impair their social life. Currently, there are simple and minimally invasive solutions to deal with these situations. One of the most widely used treatment options is the infiltrative resin technique ICON®, its action based on erosion of the surface of the lesion through the use of an acid and the subsequent infiltration of a low viscosity resin. The main objective of this narrative literature review is to recall the etiological factors, diagnosis, clinical characteristics and treatment of molar-incisive hypomineralization lesions, as well as to demonstrate the effectiveness of the ICON® technique in removing these lesions.
