Acute necrotizing ulcerative gingivitis
Background
- Also known as "trench mouth"
- Often abbreviated as ANUG
- Some literature equates as the same as Vincent's angina, and other literature suggests ANUG and Vincent's angina are different
- Severe gingival disease that may spread to local soft tissue and bone
- Must distinguish from Herpes gingivostomatitis
- Herpes has more systemic signs, less bleeding, lack of interdental papilla involvement
- Bacteria involved: anaerobic fusobacterium and Borellia spirochete[1], Treponema, Selenomonas, Prevotella
- Vincent's angina is sometimes confused with ANUG, but the former is tonsillitis and pharyngitis, and the latter involves the gums
Clinical Features
Mild presentation at the typical site on the gums of the lower front teeth.
Early
- Fever
- Halitosis
- Dental/mouth pain
- Gingival bleeding
- Teeth mobility
- Malaise
Secondary signs
- Fetid breath with metallic taste
- "Wooden teeth" feeling
- Regional lymphadenopathy
- Ulcerated, with grayish pseudomembrane or "punched out" interdental papillae
- Blunting of the typically pointed edges of the papillae
Differential Diagnosis
Evaluation
- Usually clinical
Management
Organisms involved are polymycrobial but often include Fusobacterium necrophorum, Treponema spp, Selenomonas, and Prevotella
Uncomplicated Disease
- Amoxicillin/Clavulanate 875 mg PO two times daily AND
- Metronidazole 500mg PO three times daily x 7 days [3] OR
- Clindamycin 300mg PO three times daily OR
- Doxycycline 100 mg PO BID x 10 days[4]
- If allergic to penicillin, the use Ciprofloxacin 500mg twice daily AND metronidazole 500mg PO three times daily
Additional Therapies for the immunocompromised
For patient with AIDS or immunocompromised with risk of oral candidal infection then add:
- Nystatin oral rinse four times daily x 14 days OR
- Fluconazole 200mg PO daily x 14 days
Additional Therapies for all patients
- Chlorhexidine 0.01% oral rinse BID
- Hydrogen peroxide swishing (innexpensive home remedy)
- Ibuprofen 400-600mg 3 times daily for pain
- Magic Mouthwash (multiple variations) - 300cc of 1:1:1 viscous lidocaine 2%, Maalox, diphenhydramine 12.5mg/5ml elixir
