OPG
Also written as: OPG — Orthopantomogram
Abbreviation for orthopantomogram; a panoramic extraoral dental radiograph showing the entire dentition and supporting structures in a single image.
Full Definition
OPG is the widely used abbreviation for orthopantomogram in dental and maxillofacial radiology. In clinical records, referral letters, and radiological reports, OPG is commonly used after the full term has been introduced. Some style guides and institutions prefer 'DPT' (dental panoramic tomograph) as the abbreviation; editors should apply whichever abbreviation is house-style and use it consistently. Because OPG is a trademarked brand name in some jurisdictions, some formal publications prefer the generic term 'panoramic radiograph.' Editors must ensure OPG is not used as a synonym for 'periapical radiograph' or 'cephalometric radiograph.'
Usage
Usage note: Define as 'orthopantomogram (OPG)' on first use. Some institutions prefer 'DPT'; editors should apply house style consistently. In jurisdictions where OPG is trademarked, 'panoramic radiograph' may be preferred.
