Exam #2 Review Flashcards
(35 cards)
Loe and Silness Gingival Index
0 = Normal 1 = Mild inflammation, slight color change and edema, no bleeding 2 = Moderate inflammation, redness, edema, bleeds on probing 3 = Severe inflammation, marked redness and edema, ulceration, spontaneous bleeding
Loe and Silness Plaque Index
0 = No plaque 1 = A film of plaque adhereing to the FGM and adjacent area of the tooth. This plaque may only be seen by using the probe to scrape it 2 = Moderate accumulation of soft deposits within the gingival pocket, or the tooth and the gingival margin which can be seen with the naked eye 3 = Abundance of soft matter within the gingival pockets and or on the tooth and gingival margin
How to do a PSR
Go by sextants and check depths with CIPTN
If you have a score of 3 in a quad, stop and do a full perio exam
PSR Codes
0 = Colored area visible, no calc or defective margins, no BoP 1 = Colored area visible, no calc or defective margins, BoP present 2 = Colored area visible, calc or defective margins present, BoP can be present 3 = Colored area partially visible, calc and CoP may or may not be visible 4 = Colored area not visible
O’Leary Index
Put a disclosing agent in the mouth, rinse, and count the red surfaces
Teeth have 4 surfaces, MLDF
NIDR Calculus Inex
0 = no calc 1 = supragingival calculus, but none subgingivial 2 = Supragingival and subgingival calculus OR just subgingival calculus
Reliability
If you run a test on the same patient multiple times, how likely you are to get the same result
Sensitivity
When disease is present, how likely you are to detect it
If its high, you won’t get false negatives
Specificity
When disease is not present, how likely you are to say its absent
If its high, you won’t get false positives
Predictive Value Positive
The probability of disease in a subject with a positive test result
Predictive Value Negative
The probability of no disease in a subject with a negative result
Herpetic Lesion syptoms
Painful gingivitis with redness
Ulcerations with serofibrinous exudate
Edema accompanied by stomatitis
Herpetic lesions Characterisitics
Incubation period is one week
Formation of vesicles, which rupture, coalesce, and leave fibrin-coated ulcers
Healing within 10-14 days
Recurrent HSV
Common presentation = herpes labialis
On vermillion border and/or adjacent to it
Intra-oral ulcers in attached gingiva and hard palate
Recurrent HSV treatmet
Limit bacterial superinfection (careful plaque control)
Can use antivials in immunocompromised patients
Herpes Zoster
Varicella zoster virus causes chicken pox
Small ulcers on the tongue, palate, and gingiva
Latent in the dorsal root ganglion
Unilateral lesions
2nd and 3rd branch of the trigeminal ganglion
Thrush
Candida albicans
Acquired during birth
Pseudomembranous/erosive lesions
Thrush Predisposing conditions
Antibiotics Immunosuppresion Malnutrition HIV Diabetes
Thrush oral locations
Can be just about anywhere
Thrush clinical manifestations
Pseudomembranous candidosis = white plaque
Erythematous candidosis = looks like gingivitis
Thrush diagnosis and treatment
via clinical signs and symptoms
Microscopic exam of smear - can be misleading
Correct predisposing factors and give antifungals
Lichen planus
Oral involvement alone is uncommon Dangerous because it has premalignant potential Characteristic skin lesions Varied clinical appearances Any area of the oral mucosa
Lichen planus Histopathology
Subepithelial band-like accumulation of lymphocytes
Characteristics of a type IV hypersensitivity
Fibrin in the basement membrane
Accumulation/Deposits of IgM, C3, C4, C5
Pemphigoid
Autoantibody reactions against hemidesmosomes and lamina lucida components
Detachment of the epithelium from the CT
Compliment-mediated cell destructive process may be involved in the pathogenesis
Deposits of C3, IgG, and other Ig’s
