Summary of influence factors and possible strategies improving accuracy in the diagnosis of cracks/fractures using CBCT

	Influence factors	Possible strategies improving accuracy
CBCT Unit	Voxel size	Choose smaller voxel size for narrower cracks/fractures
	FOV	Choose dentoalveolar FOV
	Exposure parameter	Increase mAs and number of basis images if possible
	Receptor technology	Inherent property of CBCT units, unelectable
	Reconstruction algorithm	Inherent property of CBCT units, unelectable
Patient (teeth)	Motion Artefact	Keep patients as still as possible
	Beam hardening artefacts	Take off removable metal materials Develop artefact reduction algorithm
	Width of the cracks/fractures	Congenital property of teeth
Observer	Experience	Advance training
