Answer 11

Generalized slight with localized moderate chronic periodontitis

Question 12

10% is at low risk

(most people fall somewhere in between)

Answer 16

putative risk factors that have been identified in cross sectional studies but not confirmed longitudinally

Question 17

what are Risk markers/predictors? give examples.

Answer 17

a characteristic associated with elevated risk for disease but may not be part of the causal chain

Furcation involvement
Calculus
History of attachment loss

Question 18

_________ _______ induces gingivitis, but host response determines if Chronic periodontitis will develop

Answer 18

bacterial plaque

Question 19

what did the chinese studies find about the relation between gingivitis and CP?

Answer 19

gingival inflammation a risk for Attachment Loss at any site

Question 20

what did the norwegian studies find about the relation between gingivitis and CP?

_________ Periodontitis is the 6th most prevalent disease in the world

Answer 26

severe

Question 27

what is a “cal” equal to?

Answer 27

probing depth + gingival recession

Question 28

what recordings are taken in the diagnosis of periodontitis?

Answer 28

Probing Depth 
Gingival Recession
CAL
BOP (expressed as % of total sites available)
Furcation involvement
Mobility
Fremitus
Bone defects

Question 29

what type of bone defects are relevant to the diagnosis of periodontitis?

Answer 29

Horizontal vs. vertical

1-wall, 2-wall, 3-wall bony defects.

Question 30

what are the goals of therapy for periodontitis?

Answer 30

Eliminate etiology
Eliminate or reduce risk factors
Prevent recurrence

Question 31

name the steps involved in initial periodontal therapy:

Answer 31

Removal of both sub and supragingival plaque
Adequate oral hygiene
Remove local and systemic risk factors

Question 32

what is the “rationale” for periodontal treatment? (AKA how do we know it works?)

Answer 32

Periodontal treatment of CP is effective (<0.1 tooth loss/year)

Non-compliant patients had double the rate of tooth loss (0.2 teeth/year)

Untreated patients lost approximately 0.6 teeth/year

Question 33

what causes the reduction in probing depths after INITIAL perio therapy?

Answer 33

gingival recession

gain of clinical attachment

pocket shrinkage

Question 34

T/F: after initial therapy, sites with initially shallow pockets tend to lose CAL (possible trauma)

Answer 34

true

Question 35

when would a patient be at a greater risk for additional attachment loss as a result of therapy?

Answer 35

if presenting multiple sites with residual probing depth >6 mm after active treatment

Question 36

T/F: it is possible to maintain a 6mm pocket during periodontitis therapy if the proper precautions are taken

Answer 36

FALSE

You cannot maintain 6 mm pockets- surgical therapy recommended
