Scanning Electrochemical Microscopy as a Tool for the Characterization of Dental Erosion

Figure 2

Approach curves obtained with a platinum microelectrode (𝑟=12.5 μm) in a 0.2 mmol L⁻¹ H₂SO₄ + 0.1 mol L⁻¹ KCl solution (pH = 3.4) for an insulating substrate (A) and a teeth sample (B), 𝐿 = ratio between tip-substrate distance and microelectrode radius. Scan rate = 10 μm s⁻¹.
