Fig. 4From: New technique for detecting cracked teeth and evaluating the crack depth by contrast-enhanced cone beam computed tomography: an in vitro studyPre-experimental cone beam computed tomography (pre-CBCT), micro-computed tomography (micro-CT), and contrast-enhanced cone beam computed tomography (contrast-enhanced CBCT) images of cracked tooth no. 8, which has a mesiodistal crack. A Horizontal plane of the crack on micro-CT (the blue arrows indicate the crack). B Horizontal plane of the crack on pre-CBCT (showing no crack).
