Necrotising Periodontal Disease
Pronunciation: NEK-roh-TY-zing pair-ee-oh-DON-tal dih-ZEEZ
A group of severe, rapidly destructive periodontal conditions characterised by necrosis of gingival tissues, interdental papilla destruction, pain, and the presence of a pseudomembrane, associated with host immunocompromise or significant stress.
Full Definition
Necrotising periodontal diseases (NPD) include necrotising gingivitis (NG), necrotising periodontitis (NP), and necrotising stomatitis (NS), representing a clinical spectrum of tissue destruction linked to specific anaerobic bacterial complexes and predisposing systemic factors such as HIV/AIDS, malnutrition, and psychological stress. The 2017 AAP/EFP classification formally recognises these as distinct from plaque-induced and non-plaque-induced gingivitis. Editors must use the preferred British/international spelling 'necrotising' (not 'necrotizing') in publications following British English house style, and the reverse for American English — and ensure consistency throughout. The outdated term 'acute necrotising ulcerative gingivitis (ANUG)' or 'trench mouth' should be flagged as deprecated in current clinical manuscripts.
Usage
Usage note: Standardise spelling to 'necrotising' (British) or 'necrotizing' (American) per house style. Flag and replace 'ANUG' and 'trench mouth' as deprecated. Distinguish NG (gingiva only, no bone loss) from NP (bone loss present) when the clinical record permits.
In Context
- "The patient presented with classic signs of necrotising gingivitis: punched-out papillae, pseudomembrane, and a distinctive fetor oris." — Emergency periodontal clinical assessment
- "Replace 'ANUG' with 'necrotising gingivitis' throughout the manuscript, consistent with the 2017 classification." — Journal editorial revision instruction
