3D data

M3#713_LACM 162449

Right lower molar (m1 or m2). The specimen was scanned with a resolution of 4.5 µm using a μ-CT-scanning station EasyTom 150 / Rx Solutions (Montpellier RIO Imaging, ISE-M, Montpellier, France). AVIZO 7.1 (Visualization Sciences Group) software was used for visualization, segmentation, and 3D rendering. This isolated tooth was prepared within a “labelfield” module of AVIZO, using the segmentation threshold selection tool.
