Use of cone beam computed tomography in periodontology

Table 1 Comparison of cone beam computed tomography and medical computed tomography are listed in the table

CBCT	Medical CT
Single rotation	Multiple rotations
Lower radiation dose	Higher radiation dose
Isotropic voxels	Anisotropic voxels
Lower cost	Higher cost
Smaller space requirement	Larger devices
Better spatial resolution	Better contrast resolution
Deficiency to display soft tissues	Clear evaluation of soft tissues
Higher scatter radiation	Lower scatter radiation

CT: computed tomography; CBCT: Cone beam computed tomography.

Table 2 The table shows the features of cone beam computed tomography and conventional radiographs

CBCT	Conventional radiography
3D imaging	2D imaging
Cross-sectional and volumetric images	Superpositions
Elimination of image deformity	Distortion and magnification
Higher radiation dose	Lower radiation dose
Higher cost	Lower cost
Larger devices	Smaller space requirement

CBCT: Cone beam computed tomography.
