Debridement
Pronunciation: deh-BREED-muh
The professional removal of microbial biofilm, calculus, and associated toxins from tooth and root surfaces using mechanical, ultrasonic, or hand instrumentation.
Full Definition
In dental hygiene, debridement refers broadly to the disruption and removal of microbial biofilm (plaque), calculus, and bacterial endotoxins from tooth surfaces and the surrounding periodontium. Full-mouth debridement (CDT code D4355) is a specific procedure performed when heavy deposits prevent comprehensive examination, and it precedes definitive periodontal diagnosis. Periodontal debridement (D4346) applies to patients with generalised moderate to severe gingival inflammation. Unlike scaling and root planing, the term 'debridement' is sometimes used to indicate a less aggressive endpoint—disruption of biofilm rather than root smoothing. Editors must check that the correct CDT code accompanies the procedure description.
Usage
Usage note: Note the French-derived pronunciation. In clinical documents, specify whether 'full-mouth debridement' or 'periodontal debridement' is intended, and include the corresponding CDT code.
In Context
- "Full-mouth debridement was performed at the initial visit to allow for accurate periodontal assessment at the subsequent appointment." — Clinical chart note
- "The hygienist documented periodontal debridement (D4346) rather than prophylaxis (D1110), reflecting the patient's diagnosis of severe gingivitis." — Insurance claim document
