4 Most clinicians support the use of CBCT scans for specific cases, such as impactions, skeletal asymmetries, root resorption, and airway concerns where conventional radiography would not provide adequate diagnostic information, 5 but they discourage routine use because of increased radiation dosages. Although three-dimensional (3D) volumetric data have provided practitioners and researchers with valuable new information, there is no consensus regarding their actual diagnostic value when it comes to making treatment decisions. Since its introduction in 1998, the use of cone-beam computed tomography (CBCT) scans in general dentistry and orthodontics and other specialties has increased in popularity. Technological advances in imaging have been able to address the shortcomings of traditional two-dimensional radiography (2D).
