(a) Shows a sagittal section providing the height of the cavity, (b) shows a sagittal section providing the depth of the cavity, (c) shows an axial section providing the diameter of the cavity and (d) shows sagittal sections illustrating the segmentation process for volume quantification. Each sagittal slice of the region containing the cavity was delineated by a turquoise green coloured border using the mouse cursor. ERR, external root resorption.
