Estudio del Esmalte Dental Humano por Microscopía Electrónica

Abstract: En el diente humano, la dentina y el esmalte presentan una estructura tipo compósito formada por cristales de hidroxiapatita (HAP) de tamaño nanométrico embebidos en una matriz de material orgánico. En este trabajo se describe el estudio de la estructura y composición química por microscopía electrónica del esmalte dental humano, así como del defecto que se observa en el centro de los cristales del esmalte, llamado “línea obscura” (CDL). Las imágenes del esmalte dental fueron tomadas por microscopia electrónic… Show more

“…The inorganic part of the tooth is made up of calcium phosphate, called hydroxyapatite, which contains impurities of sodium, magnesium, and chlorine; while the organic part of the enamel is distributed in the spaces left free by the inorganic material, whose main elements are the proteins called amelogenins and enamelins. On the other hand, the basic structure of enamel is prisms formed by hydroxyapatite that adopt a crystalline arrangement, creating elongated crystals; thus, any alteration during enamel formation leads to permanent marks because the ameloblast (the cell that forms enamel) has a little reparative capacity 1,4,5 .…”
