Q

what treatment can be done for someone with NUG/NUP

A

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

Q

characteristics of NUP

A

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

17
Q

how can you tell someone from NUP and aggressive perio

A

NUP has pain and always steady as well as HIV positive

18
Q

Three types of abscesses

A
  1. gingival abscess
  2. periodontal abscess
  3. pericoronal abscess
19
Q

causes of abscess

A

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
Q

characteristics of gingival abscesses

A

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

21
Q

where is gingival abscesses limited to

A

the gingival tissues

22
Q

characteristics of periodontal abscesses

A
  • 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
Q

major sign of periodontal pocket compared to endodontic lesion

A

you will have a vital pulp with a perio abscess

24
Q

s/s of perio abscess

A
  • constant pain that is easy to localize
  • localized swelling
  • alveolar bone loss
  • pus drainage
25
Q

treatment for perio abscess

A
  • drain pus
  • perio debridement of tooth surfaces
  • control discomfort
  • occlusal adjustment
  • antibiotics
  • salt water rinse
26
Q

characteristics of a pericoronal abscess

A

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

27
Q

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

A

operculum

28
Q

is there bone loss with a pericoronal abscess?

A

no

29
Q

s/s of pericoronal abscess

A
  • pain
  • soft tissue swelling
  • redness
  • limited mouth opening
30
Q

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

A
  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
Q

developmental deformities with mucogingival conditions around teeth

A
  1. soft tissue recession
  2. decreased vestibular depth
  3. abnormal color
  4. gingival excess
32
Q

developmental deformities on edentulous ridges

A
  1. vertical or horizontal ridge deficiency
  2. lack of gingival tissue
  3. abnormal color
33
Q

symptoms of occlusal trauma

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