Subgingival Scaling
The instrumentation of root surfaces below the gingival margin to remove calculus, biofilm, and endotoxins from within periodontal pockets.
Full Definition
Subgingival scaling is a core component of non-surgical periodontal therapy, performed using hand instruments (curettes) or powered scalers introduced beneath the free gingival margin. It targets calculus deposits and bacterial biofilm that cannot be reached by supragingival instrumentation. When combined with root planing to produce a smooth, hard root surface, the procedure is referred to collectively as scaling and root planing (SRP). Editors reviewing clinical documentation should confirm that 'subgingival scaling' is not used as a synonym for the full SRP procedure, as root planing implies an additional smoothing step. CDT code D4341 or D4342 may accompany this term in insurance-related documents.
Usage
Usage note: Do not abbreviate to 'scaling' in formal clinical documents without qualification, as scaling may refer to supragingival or subgingival procedures.
