What is NUG and NUP?

What is NUG and NUP?

Necrotizing ulcerative gingivitis (NUG) is a type of necrotizing periodontal disease in which the necrosis is limited to the gingival tissues and necrotizing ulcerative periodontitis (NUP) includes clinical attachment loss and involvement of the alveolar bone.

What causes necrotizing ulcerative gingivitis?

Acute necrotizing ulcerative gingivitis (ANUG) occurs most frequently in smokers and debilitated patients who are under stress. Other risk factors are poor oral hygiene, nutritional deficiencies, immunodeficiency (eg, HIV/AIDS, use of immunosuppressive drugs), and sleep deprivation.

What is NUG in dental?

Necrotizing Ulcerative Gingivitis (NUG) is an acute and rare (0.5-11% of the population) infectious disease of the gum tissue, which is characterized by ulceration and inflammation of the inter-dental gum tissue.

What is acute necrotising ulcerative gingivitis?

Acute necrotizing ulcerative gingivitis (ANUG) is a rapidly destructive, non-communicable microbial disease of the gingiva in the context of an impaired host immune response. It is characterized by the sudden onset of inflammation, pain, and the presence of “punched-out” crater-like lesions of the papillary gingiva.

How do necrotising diseases differ from periodontitis?

Necrotising (ulcerative) gingivitis – affects only the gums. Necrotising (ulcerative) periodontitis – involves loss of the specialised tissue that surrounds and attaches the teeth.

What is periodontal necrosis?

Abstract. ‘Necrotising periodontal diseases’ is an umbrella term for necrotising gingivitis, necrotising periodontitis, necrotising stomatitis and noma. These rapidly destructive conditions are characterised by pain, interdental ulceration and gingival necrosis which, if left untreated, can result in osteonecrosis.

What is necrotizing periodontitis?

Necrotizing periodontal diseases are a type of inflammatory periodontal or gum disease which are caused by bacteria. Most notably, the bacteria is of the fusobacteria and spirochaete species. The diseases often represent various levels of severity or stages of the same disease process, though this is not certain.

How do you treat necrotizing ulcerative periodontitis?

Treatment

1. Perform debridement under local anesthesia, including gentle scaling.
2. Remove pseudomembrane, using cotton pellet dipped in 0.12% chlorhexidine.
3. Provide the patient with oral hygiene instructions and prescribe antibacterial mouthwash (0.12% chlorhexidine, b.i.d.) or peroxide hydroxyl mouth rinse (b.i.d.).

What is necrotising stomatitis?

Necrotising stomatitis is a fulminating anaerobic polybacterial infection affecting predominantly the oral mucosa of debilitated malnourished children or immunosuppressed HIV-seropositive subjects.

How do you treat necrotizing gingivitis and periodontitis?

Treatment

1. Perform debridement under local anesthesia.
2. Remove pseudomembrane using cotton pellet dipped in chlorhexidine.
3. Provide patient with specific oral hygiene instructions to use a prescription antibacterial mouthwash: chlorhexidine 0.12% twice daily.
4. Control pain with analgesics: ibuprofen 400-600 mg 3 times daily.

How is necrotizing periodontitis diagnosed?

The clinical findings will include a history of rapid onset tissue necrosis, spontaneous bleeding, and pain. In cases of NP, the rapid loss of periodontium will also be noted, including attachment loss, periodontal ligament destruction, and alveolar bone loss producing interproximal cratering.

What is necrotising periodontitis?

What is necrotising periodontal disease? Necrotising periodontal disease is the term used to describe a group of relatively rare infections affecting the mouth in which ulceration with necrosis is the common feature. Necrosis is the term used to describe death of tissue.
