OPG
Also written as: OPG — Orthopantomogram
Abbreviation for orthopantomogram, a panoramic dental radiograph providing a two-dimensional view of the entire dentition and surrounding structures.
Full Definition
OPG (orthopantomogram) is the standard abbreviation for a panoramic dental X-ray that captures the full upper and lower jaw, all teeth, the temporomandibular joints, and the maxillary sinuses on a single film or digital image. It is also referred to as a dental panoramic tomograph (DPT) or panoramic radiograph. Editors should be aware that 'OPG' is often used generically even though OPG is a registered trademark of a specific manufacturer; some house styles prefer 'dental panoramic radiograph' or 'DPT' for neutrality. The acronym should appear in full on first use in formal publications.
Usage
Usage note: Expand to 'orthopantomogram (OPG)' on first use. Some editors prefer 'dental panoramic radiograph' to avoid reliance on a trademarked term.
