Flashcards in Nectrotizing diseases Deck (33):
1

what is necrotizing periodontal disease

uniquely involve tissue necrosis of gingival epithelium

2

what is NUG

disease limited to the gingival tissues called necrotixing ulcerative gingivitis

3

what is NUP

disease includes gingival tissues and loss of attackment and bone loss called necrotixing ulcerative periodontitis

4

what kind of infections are NUG and NUP?

acute infections of the periodontium

5

symptoms of NUG and NUP

materia alba, plaque, sloughed tissue, excessive saliva, shiny gingival tissues

6

NUG and NUP are associated with what bacteria

prevotella intermedia, spirochetes, T.D. and P.Gingivalis

7

predisposing factors of etiology

smoking, poor nutrition, fatigue, alcohol, immune dysfunction

8

NUG mostly affects what populations

students and military recruits under stress ages 15-25 years

9

NUP mostly affects what populations

HIV individuals and severe malnutritioned people

10

what treatment can be done for someone with NUG/NUP

debridement, patient self care, pain control, fluids and liquid diet, metromidazole 250 mg 3x/day to prevent secondary infections

11

NUG appearance

punched out or cratered papillae, gray-white pseudomembrane formation, bleeding upon slight manipulation, fiery red gingiva

12

what is one dominant way to tell a patient has NUG

the smell is really bad

13

s/s of NUG

pain from ulceration, swollen lymph nodes, vague feeling of discomfort, halitosis-fetid odor

14

how can you tell NUG from plaque-induced gingivitis

NUG has exudate present with gray membrane on tissues and swollen lymph nodes, and smell

15

patient characteristics with NUG

history of smoking, history of poor nutrition, HIV positive

16

characteristics of NUP

rapid gingival recession and irregular bone loss, delayed healing, and spread of infection to oral mucosa

17

how can you tell someone from NUP and aggressive perio

NUP has pain and always steady as well as HIV positive

18

Three types of abscesses

1. gingival abscess
2. periodontal abscess
3. pericoronal abscess

19

causes of abscess

blockage of an opening of an existing perio pocket forcing a foreign object into the supporting tissues of the tooth such as toothpick, and incomplete calculus removal

20

characteristics of gingival abscesses

localized, painful foreign substance in healthy gingiva, tissue is red and shiny, limited to marginal or papillae with no previous disease.

21

where is gingival abscesses limited to

the gingival tissues

22

characteristics of periodontal abscesses

-occurs at a site with pre-existing periodontal pocket
-affects deeper structures
-not limited to gingival margin
-pressure in gums, mobility, tooth is elevated

23

major sign of periodontal pocket compared to endodontic lesion

you will have a vital pulp with a perio abscess

24

s/s of perio abscess

-constant pain that is easy to localize
-localized swelling
-alveolar bone loss
-pus drainage

25

treatment for perio abscess

-drain pus
-perio debridement of tooth surfaces
-control discomfort
-occlusal adjustment
-antibiotics
-salt water rinse

26

characteristics of a pericoronal abscess

infection of soft tissue surrounding the crown of a partially erupted tooth
frequently seen around mandibular third molars

27

what is the flap of tissue that covers part of the occlusal surface called in a pericoronal abscess

operculum

28

is there bone loss with a pericoronal abscess?

no

29

s/s of pericoronal abscess

-pain
-soft tissue swelling
-redness
-limited mouth opening

30

what are developmental or acquired deformities and conditions that modify or predispose to plaque-induced disease or perio

1. tooth anatomical factors-enamel pearls, furcations, root proximity, open contacts
2. dental restorations/appliances-overhangs, poor margins, ortho bands
3. root fractures
4. cervical root resorption and cemental tears

31

developmental deformities with mucogingival conditions around teeth

1. soft tissue recession
2. decreased vestibular depth
3. abnormal color
4. gingival excess

32

developmental deformities on edentulous ridges

1. vertical or horizontal ridge deficiency
2. lack of gingival tissue
3. abnormal color

33

symptoms of occlusal trauma

1. mobility
2. sensitive to pressure
3. tooth migration
