Nectrotizing diseases Flashcards
what is necrotizing periodontal disease
uniquely involve tissue necrosis of gingival epithelium
what is NUG
disease limited to the gingival tissues called necrotixing ulcerative gingivitis
what is NUP
disease includes gingival tissues and loss of attackment and bone loss called necrotixing ulcerative periodontitis
what kind of infections are NUG and NUP?
acute infections of the periodontium
symptoms of NUG and NUP
materia alba, plaque, sloughed tissue, excessive saliva, shiny gingival tissues
NUG and NUP are associated with what bacteria
prevotella intermedia, spirochetes, T.D. and P.Gingivalis
predisposing factors of etiology
smoking, poor nutrition, fatigue, alcohol, immune dysfunction
NUG mostly affects what populations
students and military recruits under stress ages 15-25 years
NUP mostly affects what populations
HIV individuals and severe malnutritioned people
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
NUG appearance
punched out or cratered papillae, gray-white pseudomembrane formation, bleeding upon slight manipulation, fiery red gingiva
what is one dominant way to tell a patient has NUG
the smell is really bad
s/s of NUG
pain from ulceration, swollen lymph nodes, vague feeling of discomfort, halitosis-fetid odor
how can you tell NUG from plaque-induced gingivitis
NUG has exudate present with gray membrane on tissues and swollen lymph nodes, and smell
patient characteristics with NUG
history of smoking, history of poor nutrition, HIV positive
characteristics of NUP
rapid gingival recession and irregular bone loss, delayed healing, and spread of infection to oral mucosa
how can you tell someone from NUP and aggressive perio
NUP has pain and always steady as well as HIV positive
Three types of abscesses
- gingival abscess
- periodontal abscess
- pericoronal abscess
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
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.
where is gingival abscesses limited to
the gingival tissues
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
major sign of periodontal pocket compared to endodontic lesion
you will have a vital pulp with a perio abscess
s/s of perio abscess
- constant pain that is easy to localize
- localized swelling
- alveolar bone loss
- pus drainage
treatment for perio abscess
- drain pus
- perio debridement of tooth surfaces
- control discomfort
- occlusal adjustment
- antibiotics
- salt water rinse
characteristics of a pericoronal abscess
infection of soft tissue surrounding the crown of a partially erupted tooth
frequently seen around mandibular third molars
what is the flap of tissue that covers part of the occlusal surface called in a pericoronal abscess
operculum
is there bone loss with a pericoronal abscess?
no
s/s of pericoronal abscess
- pain
- soft tissue swelling
- redness
- limited mouth opening
what are developmental or acquired deformities and conditions that modify or predispose to plaque-induced disease or perio
- tooth anatomical factors-enamel pearls, furcations, root proximity, open contacts
- dental restorations/appliances-overhangs, poor margins, ortho bands
- root fractures
- cervical root resorption and cemental tears
developmental deformities with mucogingival conditions around teeth
- soft tissue recession
- decreased vestibular depth
- abnormal color
- gingival excess
developmental deformities on edentulous ridges
- vertical or horizontal ridge deficiency
- lack of gingival tissue
- abnormal color
symptoms of occlusal trauma
- mobility
- sensitive to pressure
- tooth migration
