CEJ
Also written as: CEJ — Cementoenamel Junction
Abbreviation for cementoenamel junction, the fixed tooth landmark used as a reference point for attachment level measurements.
Full Definition
CEJ is a widely used abbreviation in periodontal and restorative dentistry research. It denotes the cementoenamel junction and appears frequently in methods and results sections describing probing measurements or radiographic bone loss calculations. Editors should ensure it is introduced in full on first occurrence and is included in any required abbreviations list. Because CEJ is not universally used in all dental specialties, manuscripts intended for general oral health or restorative journals may require the full term to be used more frequently. Confusion with 'clinical endpoints' or other abbreviations beginning with 'CE' should be guarded against in cross-specialty publications.
Usage
Usage note: Always define on first use; do not assume the abbreviation is universally understood outside periodontal specialty journals.
