Midterm 2 Review Flashcards
Characteristics of Gingivitis
- confined to gingiva
- presence of plaque
- inflammation
- no loss of attachment
- reversibility
- precursor to attachment loss
- modified by endocrine, blood, medications, nutrition
Plaque induced gingivitis
- plaque present at margin
- bleeding
- increased GCF
- histological changes
- reversible with plaque removal
Non-plaque induced gingivitis
-Tooth abnormalities, dental restorations, root fractures, cervical root resorption
Aggressive periodontitis
- between puberty & 20yrs
- localized CAL in first molars/incisors at least 1 molar affected
- no more than 2 teeth other than first molar and incisor
- CAL inconsistent with plaque and calculus
- less intense gingival inflammation
- IgG2 serum antibody response
- self-limiting
Localized chronic periodontitis symptoms
<30%
Generalized periodontitis symptoms
> 30%
poor serum antibody response
Severity levels
slight- 1-2mm CAL
moderate- 3-4mm CAL
severe- >5mm
Recurrent HSV
- herpes labialis
- vermilion border
- DD: apthous ulcers
- Tx: limit bacterial superinfection, antiviral in immunocompromised patients
Herpes zoster
- varicella zoster virus
- unilateral lesions- small ulcers usually on tongue, palatal and gingiva; skin lesion may be associated with intraoral lesions
- latent in DRG
- 2nd and 3rd branch of tri gang
- tx: soft diet, rest, atraumatic plaque removal, diluted chlorhexidine rinses- supplement with antivirals
Thrush
Candida albicans
acquired during birth
pseudomembranous/erosive lesions
predisposing conditions: antibiotics, immunosuppresions, malnutrion, HIV, diabetes
diagnosis: microscopic exam, clinical signs, culture misleading (on Nickerson’s medium)
tx: fluconazole, amphotericin B
Lichen planus
- oral involvement alone
- low premalignant potential
- characteristic skin lesions
- subepithelial accumulation of lymphocytes
- type IV hypersensitivity rxn
- fibrin in basement membrane
- deposits of IgM, C3, C4, C5
Pemphigoid
- Autoantibody rxn against hemidesmosomes and lamina lucida components
- detachment of epithelium from the CT
- complement mediated cell destructive processes implicated
- deposits of C3, IgG and other Igs
Reliability
similar results when tests are performed
Validity
results accurate
NUG
- pain, ulceration and necrosis of interdental papillae
- DD: herpetic gingivostomatitis
- Predisposing: AIDS, systemic diseases, WBC disorders
- Tx: oral hygiene, mechanical debridement, systemic antibiotic therapy, surgical correction of gingival destruction
Periapical cemental dysplasia
- fibrous-osseous cemental lesions
- tooth vital
- asymptomatic
- periapical bone replaced by cellular fibroblastic tissue through cementoblastic phase
- DD: cemento-ossifying fibroma, fibrous dysplasia
