What differentiates gingivitis vs periodontitis?
CAL
What is the easiest clinical way to know if gingivitis is plaque induced or non-plaque induced?
Plaque induced will go away with prophy
T/F: Diabetes and pregnancy CAUSE periodontitis.
FALSE
Increase risk but do not cause it
What are the characteristics for aggressive periodontitis?
- Younger patients
- Systemically healthy
- Disease progression does not match clinical findings
- Robust antibody response
How do we classify aggressive periodontitis as localized?
1st molar must be involved
Molars and incisors and no more than two other teeth
How do we categorize chronic periodontitis as localized?
30% or less of probe sites are diseased
How do you differentiate between slight, moderate and severe disease?
Slight = 1-2 mm CAL Moderate = 3-4 mm CAL Severe = 5 or more CAL
How do you score the gingival index?
0 = normal 1 = mild inflam, slight color change, NO bleeding 2 = moderate inflam, redness, edema, BoP 3 = severe inflam, SELF REPORTED BLEEDING
If the patient comes in and says their gums bleed when they brush, eat, or sleep what should you expect some of their GI scores would be?
Will have some 3s due to spontaneous bleeding
T/F: You can only give a GI score of 2 if it is bleeding.
FALSE
Bleeding always will give a score of 2.
But if inflammation is bad enough without bleeding can still give score of 2
T/F: The Gingival Index is very subjective.
True
Doctors can have different scores
What are the scores for the plaque index?
0 = no plaque 1 = plaque seen by swiping probe along the margin 2 = moderate amounts of visible plaque 3 = visible plaque seen in abundance
T/F: Disclosing agents are used to do the Loe and Silness plaque index.
FALSE
It is a non-disclosed index
What are the dimensions of the PSR probe?
Ball = 1/2 mm Clear = 3 mm Color = 2 mm
TOTAL = 5.5 mm
What are the PSR codes?
0 = colored area visible, no plaque/defective margins, no BoP 1 = colored area visible, no plaque, yes BoP 2 = colored area visible, yes plaque, yes/no BoP 3 = colored area partially visible, yes/no plaque, yes/no BoP 4 = colored area not visible, yes/no plaque, yes/no BoP
Why do we do PSR?
Understand patient needs
Can only use it once on a patient
Can not use during maintenance
T/F: With PSR you record the average of each sextant.
FALSE
GI = averages per sextant PSR = worst code is put down per sextant
T/F: If one sextant is recorded as a three in PSR, the patient needs full mouth perio evaluation.
FALSE
3 on one sextant = perio eval that sextant
4 on one sextant or 3 on two sextants = full mouth perio eval
Who can get PSR eval?
Adults only during the first visit
T/F: BoP is always immediately seen upon probing.
False
Takes 30 secs - 1 minute
What is the O’Leary Index?
Uses disclosing rinse and look for stained surfaces
Calculated in percentage
Only counts presence/absence
What is a sensitive test?
You will diagnose the disease when they have it
What is a specific test?
You will know when the patient does not have disease
Will only pick up disease when it is definitely there
What is predictive value positive?
The probability of disease in a subject with a positive test
