Measurement of the crack depth of a cracked tooth on micro-computed tomography. A Appearance of the crown crack on the horizontal plane at layer 1213 (indicated with a red circle); B complete disappearance of the root crack at layer 715 (indicated with a green circle); C the distance from layer 1213 to layer 715, as measured with the ruler tool (indicated with a yellow line), is the crack depth; in this case, the depth is 8.833 mm
