Question 1

What is a DVT at the dentist?

Accepted Answer

DVT stands for Digital Volume Tomography – a three-dimensional X-ray technique specifically for the jaw and facial skull. It provides high-resolution 3D images of teeth, bones, and anatomical structures.

Question 2

Is DVT X-ray dangerous?

Accepted Answer

No. A CBCT scan exposes you to a radiation dose of approximately 5–100 microsieverts – comparable to a long-haul flight from Vienna to New York. The radiation exposure is significantly lower than that of a CT scan.

Question 3

When is a DVT necessary?

Accepted Answer

DVT is used for implant planning, wisdom tooth extraction, complex root canal treatments, orthodontics, and periodontology – whenever 2D X-rays are not sufficient.

Question 4

How long does a DVT scan take?

Accepted Answer

The actual scan time is 20–40 seconds. The entire appointment including preparation and discussion takes about 10–15 minutes.

Question 5

What is the difference between CBCT and CT?

Accepted Answer

DVT is specially optimized for the jaw and facial area and uses significantly less radiation than a CT scan, while providing sharper and more detailed images of tooth structures.
