Which group of people tend to have more cases of NUP?
NUG and NUP are similar in that they both show: necrosis, ulceration of the coronal portion of the interdental papillae and gingival margin. What feature separates NUP from NUG?
Periodontal attachment and bone loss. This is part of the destructive profession of the disease.
What is the name of the severe, progressive lesion with extension into the vestibular area and the palate as it relates to NUP?
Necrotizing ulcerative stomatitis
Feller and Lemner suggested that (these 4) can have pathogenic roles in NUP lesions in HIV seropositive individuals.
Spirochetes, Herpesviruses, Candida and HIV
The etiology of NUG and NUP can be reduced down to what four main causes?
1. Microbiological aspects - Spirochetes, Herpesviruses, Candida and HIV
2. Immunocompromised status
3. Psychological stress
As it relates to NUP, studies have found that increase levels of (this) have a suppressed effect in the immune system. We get increased level of (this) via stress, anxiety and recent stressful life events.
What kind of flora would you expect on the surface biofilm of patients with NUP?
Mixed microbial flora
What is the name of this condition that includes: dental plaque, periodontal inflammation and attachment as well as alveolar bone loss?
Which type of bone loss (vertical and horizontal) is associated with suprabony pockets? Which one for infrabony pocket formation?
Horizontal bone loss for suprabony and vertical for intrabony pocket formation.
What are the exact disease severity ranges in mm for periodontitis? Mild chronic periodontitis is what? Moderate chronic periodontitis is what? Severe periodontitis?
Mild chronic periodontitis (stage 1) - 1-2 mm or less
Moderate chronic periodontitis (stage 2) - 3-4 mm
Severe periodontitis (stage 3,4) - 5 mm or more
What is the first sign of chronic periodontitis that is found in the majority of patients during oral hygiene procedures?
Does chronic periodontitis cause people to feel pain? Yes or no?
What causes "black triangles" between teeth with people with chronic periodontitis?
This model suggests that disease progression is slow and continuous, with affected site showing a constantly progressive rate of destruction throughout the duration of disease.
This model proposes that periodontal dies progresses by short burst of destruction followed by periods of no destruction.
Random or episodic burst model
This model of disease progression suggests that periodontal destruction occurs around affected teeth during defined periods of life and that these burst of activity are interspersed with periods of inactivity or remission.
Asynchronous multiple bust model
What is considered the primary initiating agent in the etiology of gingivitis and chronic periodontitis?
Plaque accumulation on the tooth surfaces at the dentogingival junction
What are the 3 red complex bacteria?
1. P Gingivalis 2. T. Forsythia and 3 . T Denticola
What is considered to be the most important plaque retentive factor in chronic periodontitis as a result of its ability to retain and harbor plaque bacteria on its rough surface as well as inside?
Plaque retention may be influenced by (this) in chronic periodontitis.
In chronic periodontitis teeth may show these special characteristics.
Grooves, concavities and enamel projections
What are the four tissue invasive microorganisms associated with chronic periodontitis?
P. Gingivalis, A actinoycetemcomitans, F nucelatum and T. denticola
