Frequently Asked Questions (FAQs) – CBCT Scan
What is a CBCT scan?
CBCT (Cone Beam Computed Tomography) is an advanced 3D imaging technique used in dentistry to obtain detailed images of teeth, jawbones, nerves, sinuses, and surrounding structures for accurate diagnosis and treatment planning.
How is CBCT different from a regular dental X-ray?
Unlike regular 2D dental X-rays, CBCT provides
three-dimensional images
offering precise details of bone structure, nerve position, and soft tissues, which are not visible in standard X-rays.
Why is a CBCT scan recommended?
CBCT is recommended for procedures such as dental implants, root canal treatment, orthodontic planning, impacted wisdom teeth evaluation, TMJ disorders, and oral surgery to ensure safe and accurate treatment.
Is CBCT scan safe?
Yes. CBCT uses a
low radiation dose,
significantly lower than conventional medical CT scans. It is safe when performed under professional guidance and only when clinically required.
How long does a CBCT scan take?
The scanning process usually takes
20–40 seconds,
while the entire appointment may take about
5–10 minutes.
Is the CBCT scan painful?
No. The CBCT scan is completely
painless and non-invasive
. You only need to stand or sit still for a few seconds during the scan.
Do I need any special preparation before a CBCT scan?
No special preparation is required. You may be asked to remove metal objects such as earrings, spectacles, or dentures before the scan.
Can pregnant women undergo CBCT?
CBCT is generally
avoided during pregnancy
unless absolutely necessary. Always inform your dentist or radiology staff if you are pregnant or suspect pregnancy.
When will I receive my CBCT report?
CBCT images are available
immediately
, and a detailed report is usually provided the same day or as advised by your dentist.
Who interprets the CBCT scan?
CBCT scans are interpreted by
qualified dental professionals or oral & maxillofacial radiologists
to ensure accurate diagnosis.
Is CBCT necessary for every dental treatment?
No. CBCT is prescribed only when advanced 3D imaging is required. Routine dental treatments may only need standard X-rays.
Can children undergo CBCT?
Yes, CBCT can be done for children when clinically indicated, using
child-specific low radiation protocols.
How much radiation does a CBCT scan involve?
CBCT delivers
much lower radiation
than medical CT scans and is comparable to a few dental X-rays, depending on the scan area.
Where can I get a CBCT scan?
CBCT scans are available at advanced dental clinics and imaging centers equipped with modern CBCT machines.
