CBCT - Cone Beam Computed Tomography X-ray
What is CBCT?
A CBCT or cone-beam computed tomography is used by dentist to capture a three-dimensional (3D) image of the patient’s head and neck anatomy including teeth, jaw and airway. It is now available in our clinic in Johor Bahru.
This advance machine rotates around the head in less than a minute, emitting cone shaped x-ray beam. The data gathered in the digital sensor will then used to reconstruct a 3D image of the teeth or jaws. The process is quick, painless and non-invasive.
Modern dentistry uses CBCT to provide 3D imaging for more accurate diagnosis and treatment in many areas.
- Wisdom teeth
- Impacted/unerupted tooth
- Root canal treatment
- Implant treatment planning
- Airway assessment
- Trauma and bone fracture
- TMJ (temporomandibular joint) diseases
- Other oral pathology
Is it safe?
CBCT emits far less radiation compared to traditional medical CT scan, thanks to its innovative cone-shaped X-ray and digital sensors. For example, the typical radiation dose for dental CBCT will vary from 18–200 µSv depending on the size of field of view (FOV). However, a typical effective dose from medical CT scan of an adult brain is around 2000µSv.
Our dentists follow strict radiology safety guidelines and limit the indication of CBCT x-ray to only those who need it in their diagnosis and treatment where benefits outweigh the risks.
