Supragingival
Pronunciation: soo-pruh-JIN-jih-vul
Located or occurring above the gingival margin; used to describe calculus, plaque, restorations, or scaling procedures coronal to the gum line.
Full Definition
The prefix 'supra-' (above) combined with 'gingival' (relating to the gingiva) designates the zone coronal to the free gingival margin — the portion of tooth surface and any deposits or restorations visible above the gum line. Supragingival calculus is typically white or yellowish, less mineralised than its subgingival counterpart, and more accessible during routine scaling. In restorative dentistry, margin placement is described as supragingival, equigingival, or subgingival, influencing periodontal health and accessibility for impression-taking. Editors must not conflate supragingival with 'subgingival', as treatment protocols differ substantially.
Usage
Usage note: Always hyphenate variants such as 'supra-gingival' only if house style requires it; the closed form 'supragingival' is standard in dental literature.
