      <dc:description>The aim of this study was to assess the mechanical and chemical performance of sound&#xd;
and caries-affected dentin (CAD), after Zn-free vs containing amalgam restorations&#xd;
placement and thermocycling. Dentin surfaces were studied by Atomic Force&#xd;
Microscopy (AFM) analysis for surface morphological characterization (including fibril&#xd;
diameter assessment), nano-indentation (to measure nano-hardness-Hi and modulus of&#xd;
Young-Ei), and single point Raman spectroscopy for chemical analysis. Measurements&#xd;
were performed before amalgam placement, after amalgam removal, and after 3 months&#xd;
of thermocycling (100,000cy/5 ºC and 55 ºC). Restorations increased both Hi and Ei at&#xd;
intertubular dentin of CAD. The highest values of Hi were achieved at intertubular&#xd;
dentin after restoring with Zn-containing amalgams. Remineralization of dentin was&#xd;
attributed to the increase of both amorphous and crystalline new mineral, as lower&#xd;
degrees of crystal imperfections in junction with crystal disorders, and improvement in&#xd;
structural stability of collagen were found. Higher presence of minerals were also&#xd;
confirmed after the decrease of fluoridated apatite and the increase of the total water&#xd;
content. Proteoglycans, lipids, and proteins, augmented in both sound and CAD,&#xd;
providing support for the mineral growing. The increase of bands assigned to vibration&#xd;
of carbonate calcium phosphate contributed to a decrease of crystallinity.</dc:description>
