Nectrotizing diseases

Question 1

what is necrotizing periodontal disease

Answer 1

uniquely involve tissue necrosis of gingival epithelium

Question 2

what is NUG

Answer 2

disease limited to the gingival tissues called necrotixing ulcerative gingivitis

Question 3

what is NUP

Answer 3

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

Question 4

what kind of infections are NUG and NUP?

Answer 4

acute infections of the periodontium

Question 5

symptoms of NUG and NUP

Answer 5

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

Question 6

NUG and NUP are associated with what bacteria

Answer 6

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

Question 7

predisposing factors of etiology

Answer 7

smoking, poor nutrition, fatigue, alcohol, immune dysfunction

Question 8

NUG mostly affects what populations

Answer 8

students and military recruits under stress ages 15-25 years

Question 9

NUP mostly affects what populations

Answer 9

HIV individuals and severe malnutritioned people

Question 10

what treatment can be done for someone with NUG/NUP

Answer 10

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

Question 11

NUG appearance

Answer 11

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

Question 12

what is one dominant way to tell a patient has NUG

Answer 12

the smell is really bad

Question 13

s/s of NUG

Answer 13

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

Question 14

how can you tell NUG from plaque-induced gingivitis

Answer 14

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

Question 15

patient characteristics with NUG

Answer 15

history of smoking, history of poor nutrition, HIV positive

Question 16

characteristics of NUP

Answer 16

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

Question 17

how can you tell someone from NUP and aggressive perio

Answer 17

NUP has pain and always steady as well as HIV positive

Question 18

Three types of abscesses

Answer 18

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

Question 19

causes of abscess

Answer 19

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

Question 20

characteristics of gingival abscesses

Answer 20

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

Question 21

where is gingival abscesses limited to

Answer 21

the gingival tissues

Question 22

characteristics of periodontal abscesses

Answer 22

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

Question 23

major sign of periodontal pocket compared to endodontic lesion

Answer 23

you will have a vital pulp with a perio abscess

Question 24

s/s of perio abscess

Answer 24

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

Question 25

treatment for perio abscess

Answer 25

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

Question 26

characteristics of a pericoronal abscess

Answer 26

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

Question 27

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

Answer 27

operculum

Question 28

is there bone loss with a pericoronal abscess?

Answer 28

no

Question 29

s/s of pericoronal abscess

Answer 29

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

Question 30

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

Answer 30

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

Question 31

developmental deformities with mucogingival conditions around teeth

Answer 31

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

Question 32

developmental deformities on edentulous ridges

Answer 32

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

Question 33

symptoms of occlusal trauma

Answer 33

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