Supragingival
Pronunciation: soo-pruh-JIN-jih-vul
Located or occurring above the gingival margin (the gum line).
Full Definition
Supragingival is an adjective describing structures, deposits, or clinical activity situated above the free gingival margin—that is, the visible portion of the tooth surface above the gum. In dental clinical notes and procedure descriptions, it most frequently modifies 'calculus', 'plaque', or 'scaling'. Editors must distinguish it from its antonym 'subgingival', which refers to activity below the gum line. The prefix 'supra-' is not hyphenated in this compound; both supragingival and subgingival are written as single words. Misuse of these directional terms in clinical documentation can have billing and legal implications.
Usage
Usage note: Write as a single word without a hyphen. Always paired with or distinguished from 'subgingival' in clinical contexts.
