OPG
Pronunciation: O-P-G (spelled out)
Also written as: OPG — Orthopantomogram
Abbreviation for orthopantomogram; the standard panoramic dental radiograph used in orthodontic record-taking.
Full Definition
OPG is the widely used clinical abbreviation for orthopantomogram (or orthopantomograph), the panoramic dental X-ray that captures both jaws and associated craniofacial structures in one image. In formal documents, OPG must be expanded at first use. Some style guides and journals prefer DPT (dental panoramic tomograph) or simply 'panoramic radiograph'; editors must apply the publication's preferred form consistently. The abbreviation should not be used in patient-facing materials without explanation.
Usage
Usage note: Define at first use in all formal documents. Confirm the journal or publisher preference between OPG and DPT before finalising copy.
