PCD
Also written as: PCD — Periapical Cemental Dysplasia
Abbreviation for Periapical Cemental Dysplasia, a benign fibro-osseous jaw lesion occurring at tooth apices in vital teeth.
Full Definition
PCD is the standard abbreviation used in oral and maxillofacial radiology literature for periapical cemental dysplasia. It should be defined on first use in any document before being used as a standalone abbreviation. Editors should be aware that PCD can also represent 'primary ciliary dyskinesia' in other medical specialties; context is essential to disambiguate. In dental radiology documents, PCD invariably refers to the jaw lesion. Its use as an abbreviation is appropriate in technical and research contexts but should be expanded in patient-facing or lay-audience materials.
Usage
Usage note: Always expand on first use. Clarify specialty context if the document spans multiple clinical disciplines to avoid confusion with 'primary ciliary dyskinesia.'
In Context
- "Three cases of PCD were identified incidentally on routine panoramic radiographs; none of the affected teeth required endodontic intervention." — Retrospective radiographic study
- "The abbreviation PCD was introduced without expansion on first use; the editor inserted the full term 'periapical cemental dysplasia' at first mention." — Manuscript editing note
