Dose Adjustments for Accuracy: Ultralow Dose Radiation 3D CBCT for Dental and Orthodontic Application
Cone beam computed tomography (CBCT) is increasingly popular when gathering initial patient imaging records for diagnosis and treatment planning. Although traditional two-dimensional panoramic or cephalometric radiographs can provide sufficient information to perform treatment in most cases, clinicians have become aware of the distortion inherent with these radiographs that can affect angular and linear measurements and, more importantly, tooth location and tooth-bone-jaw relationships.
A problem with CBCT technology is that its routine use poses a health risk as a source of ionizing radiation, especially in orthodontic patients who are mostly growing patients, preadolescent, and adolescent.
But what if there was a way to reduce the radiation dose and still reap the benefits of this technology to better serve our patients? This chapter will discuss dose adjustment methods used in the medical arena and their applications in the dental profession, with special focus on orthodontics.
