Evaluation of Surface Roughness Characteristics Using Atomic Force Microscopy and Inspection of Microhardness Following Resin Infiltration with Icon.

Objective: The aim of this study was to evaluate the surface roughness via atomic force microscopy (AFM) as well as to evaluate the microhardness values of Icon in comparison with sound and demineralized enamel in a large subject group.

Materials And Methods: Enamel samples were prepared from sound bovine incisors and randomly allocated into either AFM (n = 60) or microhardness (n = 60) groups. The AFM group was divided into control (n = 30) and Icon (n = 30) subgroups.
