Why it matters clinically
DDJ uses the term for imaging decisions: when a volumetric view adds clear value for treatment beyond plain 2D radiographs.
Dental term
cone beam computed tomography (DVT)
Three-dimensional dental X-ray that shows the jaw and teeth as a volume rather than a flat single-plane image.
How DDJ writes it
On first use: cone beam computed tomography (CBCT/DVT). After that, the acronym; lay term "3D X-ray".
What to avoid
- Do not frame it as routine diagnostics.
- Do not recommend it without justification and radiation protection (ALARA).
