ALL YOU WANTED TO KNOW ABOUT CBCT
CBCT is a useful tool for imaging the craniofacial area that produces more realistic images that facilitate interpretation.
All the previous conventional and digital intraoral and extraoral procedures, as they were two dimensional (2D) projections, suffer from several limitations. These limitations were magnification, distortion, superimposition and misrepresentation of structures. CBCT has achieved a transition of dental imaging from 2D to 3D images. Moreover, the application of sophisticated software, contribute to the reestablishment of imaging sciences role
Dental Clinical Applications of CBCT
As with any X-ray exposure, CBCT entails a risk to the patient. It is essential that any X-ray examination should show a net benefit to the patient, weighing the total potential diagnostic benefits it produces against the individual detriment that the exposure might cause. The efficacy, benefits and risk of available alternative techniques having the same objective but involving less (or no) exposure to X-rays should be taken into account (1).
In order that the justification process can be carried out, it is essential that selection of CBCT is based on the individual patient’s history and a clinical examination. The ‘routine’ use of CBCT on patients based on a generalized approach rather than individual prescription is unacceptable. A ‘routine’ (or ‘screening’) examination is defined as one in which a radiograph is taken regardless of the presence or absence of clinical signs and symptoms (1).
Choosing CBCT for a patient should also be based upon consideration of the prevalence of diseases, their rates of progression and the diagnostic accuracy of CBCT, compared with traditional techniques, for the application in question. The following are the uses of CBCT in Pediatric dentistry.
1. The Developing dentition
Many children seek orthodontic treatment. Usually the treatment starts at the time period of mixed dentition stage.
