Important

Question 1

clinical signs of inflammation

Answer 1

red (erythema)
enlarged tissues (edema)
spongy
IDP bulbous
Probing depths 1-3mm
BOP

Question 2

key points if diagnosis is gingivitis

Answer 2

no apical migration of the JE
reversible
good patient self-care

Question 3

gingival pocket

Answer 3

due to gingival enlargement
NO attachment loss
NO apical migration of JE

Question 4

periodontal pocket

Answer 4

sulcus over 3 mm in depth
apical migration of JE
loss of periodontal tissues/bone

Question 5

code 3 PSR exception

Answer 5

if 2 or more sextants score code 3: a comprehensive full mouth periodontal assessment is required

Question 6

code 0

Answer 6

no bleeding/calculus/defective margins

Question 7

code 1

Answer 7

BOP
no calc/defective margins, remove biofilm

Question 8

code 2

Answer 8

calculus and/or defective margins present
biofilm removal
cal removal
defective margins corrected

Question 9

code 3

Answer 9

probing depths 4-5.5mm
calc/defective margin/BOP may or may not be present
a comprehensive perio assessment required for affected sextant

Question 10

CAL

Answer 10

a clinical measurement of the true perio support around the tooth

Question 11

margin at normal level

Answer 11

probing depth and CAL are the same

Question 12

margin significantly above CEJ

Answer 12

subtract gingival margin level from probing depth

Question 13

gingival margin receded

Answer 13

gingival margin is added to probing depth

Question 14

calculate attached gingiva

Answer 14

total width - probing depth = level of attached gingiva

Question 15

a local contributing factor can

Answer 15

increase plaque biofilm
increase plaque biofilm pathogenicity
can cause direct damage to the periodontium

Question 16

why do we scale

Answer 16

pathogenic potential
irregular surface covered in bacteria
difficult to control disease
alters contours of teeth

Question 17

supracrestal tissue attachment

Answer 17

zone of soft tissue coronal to alveolar crest
biologic width
violated if margin of restoration encroaches upon this zone: body will create room and result in bone resorption and gingival recession

Question 18

faulty removable prosthetics and appliances

Answer 18

patient education
remove daily for cleaning
can promote biofilm and trigger perio inflammation

Question 19

direct damage from patient habits

Answer 19

improper use of plaque biofilm control aids
tongue thrusting
mouth breathing
traumatic tooth brushing
oral jewelry

Question 20

traumatic tooth brushing concerns

Answer 20

gingival recession may lead to associated labial bone loss known as dehiscence

Question 21

primary trauma from occlusion

Answer 21

injury to healthy periodontium due to excessive occlusal forces
from high restoration, ill-fitting bridge/partial denture
manifestations: wider PDL space, tooth mobility, tooth or jaw pain

Question 22

secondary trauma from occlusion

Answer 22

injury from normal or excessive occlusal forces applied to previously damaged periodontium by periodontitis
concern: rapid bone loss
tip teeth laterally

Question 23

periodontitis as a manifestation of systemic disease

Answer 23

when systemic condition is the major predisposing factor and the bacterial infection is secondary

Question 24

systemic diseases/conditions affecting the periodontal supporting tissues

Answer 24

increases the individual’s susceptibility to periodontal infection by modifying the host response to the bacterial infection

Question 25

biologic equilibrium

Answer 25

state of balance in body between bacterial plaque and host

Question 26

risk assessment involves identifying elements that either

Answer 26

predispose a patient to developing perio disease or influence the progression of disease that already exists
