Flashcards

Necrotizing Periodontal Disease

A severe gum infection that destroys gum tissue and bone. It's characterized by painful ulcers, a white-grey slough, and bad breath.

Bacteria involved in NUG

The bacteria that are commonly found in necrotizing periodontal disease. They include spirochetes like Borrelia Vincenti and Fusobacterium.

Predisposing factors of Necrotizing Periodontal Disease

Pre-existing gingivitis (inflammation of the gums), poor oral hygiene, smoking, stress, and a weakened immune system (especially in cases of uncontrolled HIV).

Ulcers in NUG

A common symptom of necrotizing periodontal disease. The ulcers are deep and can extend beyond the gum line, potentially affecting other tissues.

Pseudo membrane in NUG

A thick, yellowish coating on the gums that is a sign of NUG. It's formed by dead tissue and bacteria.

Treatment for NUG

The primary treatment for NUG. It includes cleaning the affected area, using mouthwashes (e.g., chlorhexidine), and sometimes, antibiotics (e.g., metronidazole).

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.
