“…Although conventional radiographs, because they are two-dimensional, do not allow the qualitative visualization of images with high magnification (up to 300,000 X) and resolution, nor the observation and recording of three-dimensional images such as scanning electron microscopy -SEM (PICON et al, 2006). Therefore, studies using SEM in bone tissues allow the analysis of the bone architecture, bone neoformation and, in cases of bone repair, its maturation (CRUZ et al, 2007;SCHIAPPARELLI;ZEFIRO;TACCINI, 2009).
