GCF
Also written as: GCF — Gingival Crevicular Fluid
Abbreviation for Gingival Crevicular Fluid; a sulcular exudate collected as a periodontal biomarker in clinical and research settings.
Full Definition
GCF stands for Gingival Crevicular Fluid, the serum-derived inflammatory exudate found in the gingival sulcus. In periodontal literature, the acronym appears frequently in methods and results sections of biomarker studies. Editors must ensure the acronym is defined on first use and that the expanded form is spelled as three separate words with initial capitals. GCF should not be confused with 'GBR' (Guided Bone Regeneration) or other similar-looking periodontal acronyms. Some older literature uses 'GF' for 'gingival fluid,' which is a less precise variant.
Usage
Usage note: Always expand on first use. Confirm the author has not confused GCF with other three-letter periodontal acronyms.
