Comparison of radiation dose for implant imaging using conventional spiral tomography, computed tomography, and cone-beam computed tomography

Awareness and Attitude among Dental Professional towards CBCT

“…they reported that CBCT delivers lowest radiation dose to organs while spiral multi slice CT delivers highest dose. 7 About 43.90% believed that CBCT would be used in the near future in all areas of dentistry, 7.32% believed that it will not be commonly used in routine practice and 12.2% have no idea. 39.02% thought that it is necessary for CBCT to be available at their speciality, 56.1% did not think as necessary and 4.88% have no idea.…”

Measuring absorbed dose for i-CAT CBCT examinations in child, adolescent and adult phantoms

“…6 However, dental CBCT is often used to supplement conventional radiography such as bitewing, periapical, panoramic and cephalometric radiographs. The radiation doses from full FOV dental CBCT scans have been measured to be 4-42 times the dose from a panoramic radiograph.…”

Comparison of two cone beam computed tomography multiplanar reconstruction orientation protocols

“…Cross-sectional information can be acquired with conventional medical computed tomography (CT) [4] . Despite the usefulness of medical CT in implant imaging [7][8][9] , the high cost, limited availability, and relatively high radiation exposure make its routine use impractical [5][6][7][8][9] . Cone Beam Computed Tomography (CBCT) is a relatively newer 3D imaging modality specifically designed for oral and maxillofacial regions [9][10][11] .…”

“…Unlike two-dimensional (2D) conventional radiographs, images obtained from CBCT scans are free of geometric distortion and superimposition [12,13] . Previous studies have established both the accuracy of linear measurements on 3D surfacerendered images and 2D tomographic slices generated from CBCT data [5,[19][20][21] as well as the utility in determining available bone height and width before implant selection [14][15][16][17] .…”
