OPG
Also written as: OPG — Orthopantomogram
Abbreviation for orthopantomogram, a panoramic dental radiograph showing the full dentition and surrounding structures in a single image.
Full Definition
OPG stands for orthopantomogram (also rendered as orthopantomograph), a two-dimensional panoramic X-ray that captures all teeth, both jaws, the temporomandibular joints, and supporting bone in one wide-format image. It is among the most common radiographic records requested at the start of orthodontic treatment. Editors should note that 'OPG' is the standard abbreviation in clinical documentation and should be expanded on first mention in formal reports. The synonym 'panoramic radiograph' or 'dental panoramic tomograph (DPT)' may appear in British clinical writing.
Usage
Usage note: Expand to 'orthopantomogram (OPG)' on first reference in formal reports. In the UK, 'DPT' is also widely used; ensure consistency within a single document.
