Exam 3 Flashcards
An acute infection involving a circumscribed collection of pus in the periodontium
Abscess of the periodontium
Consists primarily of dead and dying neutrophils, bacteria, cellular debris, and fluid leaked from blood vessels
Pus
The process of forming pus
Suppuration
What are the characteristics of acute periodontal conditions?
Sudden onset of the condition
Rapid course of progression
Accompanied by pain and discomfort
May be unrelated to preexisting gingivitis or periodontitis
What are the causes of abscesses of the periodontium?
Blockage of the orifice or pocket, accidentally forcing a foreign object into the tissues, and incomplete calculus removal in a pocket
An abscess of the periodontium that is primarily limited to the gingival margin or to the interdental papilla without the involvement of deeper structures
Gingival abscess
An abscess of the periodontium that affects deeper structures of the periodontium as well as the gingival tissues
Periodontal abscess
Flap of gingival tissue that covers a portion of the crown of a partially erupted tooth that can become infected
Operculum
Where does pericoronitis most often occur?
The lower third molar
Fundamental treatment steps for a patient with pericoronitis
1 establish a path of drainage for the pus
2 irrigation of the undersurface of the operculum
3 thorough periodontal debridement if the tooth surfaces in the area of the abscess
4 relief of pain
An acute infection of the periodontium that is limited to the gingival tissues
Necrotizing ulcerative gingivitis
Other names for NUG
Vincent infection
Trench mouth
Ulceromembranous gingivitis
Acute NUG (ANUG)
Cell death
Necrosis
The loss of epithelium normally covering underlying connective tissue
Ulceration
Highest incidence of NUG is seen in patients between
20 and 30 years old
