Datation du stress induisant les hypominéralisations de l'émail à partir d'un échantillon de premières molaires permanentes

Abstract : Molar incisor hypominéralisation (MIH) is a structural defect of the permanent first molars (PFMs) that causes white, creamy or yellow-brown demarcated opacities. Over thirty etiological theories have been proposed at various stages of a child’s development (0 to 4years). MIH stress dating was measured with layers from Reid and Dean’s research on histological slices splitting enamel formation time in decile. The end of the enamel formation, in the sample’s hypomineralised area, is on average 1.3 and 1.8 year and can be up to 1.3 and 2.7 years. No defect has been recorded in the last two deciles. No difference was found in the occurring time of the defect in regard to its color or localization. Very few studies about MIH mapping and dating and about precise age range etiology were found. That is why no etiology could be excluded.
