Test 2 Flashcards
leukoedema
characterized by white hue or vertical wrinkles that disappear when skin is stretched
Actinic Keratosis
A preconcerous skin condition
what drugs cause gingival enlargement
Dilantin, cyclosporin, calcium blocckers
Oral Lichen Planus Description
oral Lichenoid mucositits
interlacing white lines with circular radiating lines
Caused by reaction to drugs( thiazides, beta blockers diaretics) or amalgam
purpura or ecchymosis
caused by extravation of blood
Described as red purple blotches mixed with yellow greenish backgroud
Epulis fissuratum
Denture induced: inflammatory fibrous hyperplasia
Described as
Multiple soft tissue enlargements or thick folds with prominent fissure where denture flanges fit
categories as a physical injury
Morsicato buccarum/ Labiorum
Physical injury
Cheek and lip biting , a factitial injury
described by white patches of buccal and labial mucosa with ragged or shredded surface and areas of red underneath
Irritation from masticatory function may cause
Frictional Keratosis on gingiva
frictional keratosis on alveolar mucosa and retromolar pad/ridge
Chemical injury
Aspirin burn
thin white folds on mucosa can be peeled off
Leukoplakia
a white patch on
the oral mucosa which cannot
be removed by scraping and
cannot be attributed to any
other diagnosable disease
Squamous cell carcinoma
A mixed red and white area at commisural mucosa, with IRREGULAR borders and mulberry looking growth.
Induration to palpulation
can be multiple red lesion on lip covered in crust stayed for more than 3 months
what is the major contribbuter of resting salivary gland
Submandibular gland
What is the main contributor of stimulate salivaa
Parotid gland
whats the difference between xerostoma and hyposalivation
xerostomia is a sensation
Hyposalivation is a reduced salivary flow rate
What is hyper salivation called
sialorrhea
how long would it take to notice xerostomia
sometimes until more than 50% is gone
What are signs of hyposalivation
thin and atropic mucosa mouth mirror sticks to muccal mucosa Limited saliva flow Disappearing of filiform and fungiform papillae Cervical decays Oral candidiasis
When is it considered hyposalivation
less than .1 g(ml)/minute unstimulated
less than .7 g(ml)/minuted stimulaateds
or both
When are men considered anemic
when Hb gets 13.5 g/dl
When are women considered anemic
Hb 12 g/dl
lichen planus has what kind of histology
Civatte bodies&
Intense fibrinogen deposition at the basement membrane zone is
typical of oral lesions of lichen planus
Ecchymosis or purpura
extravasion of blood to skin surface
epilus fissuratum
denture induced inflammatory fibrous hyperplasia
- T/F Q: ulceration is total loss of epithelial layer. Erosion is thinning of epithelial layer
True and true
angiodema is caused by what drug
Ace inhibitors
what causes jaw bone necrosis
osteoporosis
cancer patients on anti resorptive and antiangiogenic drugs
pagent disease, osteopenia
radionecrosis
when bone necrosis happens above 60 gray scale
important anti resorptive drug
Bisphosphanate
Trismus
muscle is involved inability to open, radiotherapy can contribute to trismus
acceptable INR range Patient on oral anticoagulant therapy (AT) with warfarin (Coumadin):
2-3
Patient on AT with warfarin due to artificial heart valve may have INR up to
3.5
iNR reference range
0.8-1.2
TRUE OR FALSE
INR can be used in assessing coagulation status of patients not take vitamin K
False
INR CAN NOT be used for assessing coagulation status of patients NOT taking vitamin K antagonists
true or false
INR can be used to accurately reflect inhibition of coagulation in liver disease
False
The effect of ISI is much greater on PT in warfarin users than in liver disease individuals, therefore INR does NOT accurately reflect inhibition of coagulation in liver disease
True or false
INR has no value in the new oral anticoagulants users (factor Xa inhibitor[Xarelto, Eliquis] or Factor IIa inhibitor[Pradaxa])
True
what is PTR (prothrombin time ratio)
is the patient’s PT divided by that of reference control plasma PT: PTR = (PT)/(Ref Control PT)
ISI stands for
International service index
What is PT=Prothrobin Time used for
Detection of inherited or acquired couagulation defects
deficiencies in factor II V VII X and Fibrinogen
monitoring warfarin ratio using INR
aPTT=
activated Partial Thromboplastin time
Severe neutropenia
(ANC < 500) — severe risk of bacterial infection.
ANC=Absolute neutrophil count
with Platelet count when does risk of increase bleeding occur
50,000/mm^3 =50k microliters
with platelet count when does spontaneous bleeding occur
20,000/mm^3= 20K microL or less
When is a patient considered thrombocytopenic
150,000 mm^3= 150K or less
E1 caries
lesion is limited to the outer 1/2 of the enamel
Triangle base is at surface pointy part to the pulp… like drill(radiolucent)
seen radiographically only on Proximal surfaces
E2
lesions penetrates more than 1/2 trough enamel up to DEJ
Can be seen radiographically ONLY on proximal surface
D1
lesion in dentin less than 1/3
Rounded, poorly defined radiolucent
Difference between enamel lesion. and dentin lesion
Enamel - sharp triangle
Dentin- rounded poorly defined
D2 lesion
extends more than 1/3 but less than 2/3 towards the pulp
D3
lesion extends more than 2/3 towards the pulp
which disease has the fistula
CAA
physical examination methods
inspection palpation Percussion" auscultation Instrumentation cold test
true or false
a diagnosis is complete once u discover disease name
false
incomplete diagnosis until cause is I identified
