Periodontal examination Flashcards
when do you do a medical consult for a diabetic patient?
if the patient does not know HbA1c or if it was taken >3 months ago
What four questions do you ask the diabetic pt?
1) how often do you check your blood sugar levels?
2) how often do you see your dr to check your diabetes control?
3) do you know your most recent HbA1c value?
4) did you eat and take your medications today?
what percentage should the HbA1c be below?
<10%
what should the blood glucose level be below?
<200 mg/dl
can dental emergency tx be conducted outside the range in diabetes pt’s?
yes (infection may increase blood glucose value)
what are clinical photographs useful for?
recording appearance of tissue, recession, papilla loss, and for patient education
when recording plaque how many surfaces per tooth are recorded?
6 surfaces
what will result in corrosion?
acidic foods/beverages
acid reflux
bulimia
where does abrasion come from?
mechanical wear other than that of mastication
what results in abfraction?
microfractures at the CEJ from tooth flexure due to occlusal forces
what is attrition?
occlusal or incisal wear
what is class I mobility?
tooth moves buccal-lingually <1 mm
what is class II mobility?
tooth moves buccal-lingually 1 mm
what is class III mobility?
tooth moves buccal-lingually >1 mm or is depressible in the socket
how do you check for fremitus?
place finger on facial of tooth
ask pt to gently tap up and down
feel for vibration or movement of tooth
how do you check for pathologic tooth migration?
check occlusion
check for habits (tongue thrust)
what are the signs of occlusal trauma?
mobility
widened PDL
vertical defects
pathologic tooth migration
root resorption
what are parafunctional habit examples?
bruxism
clenching
holding objects b/w teeth
what are the issues of the plunger cusp?
may lead to: food impaction, tooth migration, open contact formation (opens up the contact)
absence of _________ is a good predictor of future periodontal stability
BOP
how do you determine the biologic depth?
histologically
T/F biologic depth is the same as the biologic width
FALSE
what is the biologic depth?
distance b/w gingival margin and the base of the pocket (coronal end of the junctional epithelium)
how do you determine the probing depth?
clinically
what is the Hamp classification?
furcation bone loss or
furcation involvement
what is degree I of hamp classification?
<3 mm, roof of furcation detectable
what is degree II of hamp classification?
≥3 mm, not completely through furcation
what is degree III of hamp classification?
probe passes completely through furcation, covered with tissue
what is grade IV of Glickman classification?
through-and-through loss of interradicular bone, with total exposure of furcation owing to gingival recession
what is the equation for CAL?
CAL = PD + Gingival margin
when is the gingival margin positive?
when it is apical to CEJ
when is the gingival margin negative?
when it is coronal to CEJ
what laboratory aids can you use for the pt?
blood tests
genetic tests
