Figure 5From: A new esthetic fiber-reinforced polymer composite resin archwire: a comparative atomic force microscope (AFM) and field-emission scanning electron microscope (FESEM) study Image showing surface roughness analysis of FRPC wire of ICE-FRPC group. The FRPC wire showed maximum roughness with Ra = 496.13 nm, RMS = 635.49 nm, and surface area difference of 25.6% (original magnification ×40, 40 μm).Back to article page
