Study Notes
Necrotising Periodontal Diseases (NUG)
- Acute infection affecting marginal gingiva.
- Characterised by a white/grey slough of necrotic tissue, with inflamed tissue adjacent to it.
- Necrotic areas begin at papillae tips, appearing as punched-out ulcers.
- Key bacteria involved are spirochaetes, Borrelia vincentii, and Fusobacterium.
Predisposing Factors for NUG
- Pre-existing gingivitis indicating an unhealthy oral cavity.
- Poor oral hygiene (OH).
- Smoking.
- Stress.
- Compromised immune system (e.g., uncontrolled HIV).
Signs and Symptoms of Necrotising Ulcerative Gingivitis (NUG)
- Ulcers primarily located on the papillae tips of the gingival margin.
- Formation of a pseudo-membrane.
- Pain.
- Distinct, strong bad breath (halitosis).
- Extent beyond 10mm beyond the gingival margin or mucogingival junction—indicating necrotising stomatitis.
Treatment for NUG
- Debridement (removal of necrotic tissue)—can be painful.
- Mouthwashes like chlorhexidine or hydrogen peroxide.
- Potential antibiotic therapy using metronidazole.
- Addressing predisposing factors after the acute phase to prevent recurrence.
