New Periodontal X

Question 1

What’s healthy periodontium ?

Answer 1

● Absence or up to two sites of clinically detectable
inflammation
● Minimal or no bleeding on probing
● Normal (≤3 mm) probing depths
● Can be on an intact (no attachment or bone loss) or
reduced (previous attachment or bone loss) periodontium

Question 2

What’s gingivitis ?

Answer 2

● Inflammation
● Erythema, edema, bleeding on probing
● Normal (≤3 mm) probing depths
● Stable periodontium with no current
progressive attachment or bone loss

Question 3

What’s periodontitis?

Answer 3

● Loss of periodontal support due to
microbial-associated, host-mediated
inflammation
● Deeper (≥4 mm) probing depths
● Presence of interproximal attachment loss
from current disease state; not including
attachment loss from a history of disease in
currently stable patients

Question 4

Severity based on what ?

Answer 4

Interdental CAL
Percent of bone loss.
Number of teeth lost due to periodontitis

Question 5

Complexity based on what ?

Answer 5

Max probing depth
Type of tooth loss horizontal or vertical
Furcation involvement
Tooth mobility
Number of teeth remaining

Question 6

Grading based on what ?

Answer 6

Primary criteria :
1. radiographical bone loss or CAL over past 5 years
2. Percent of tooth loss to age
3. Case phenotype ( plaque deposition to destruction )

Modified criteria : severity of smoking and diabeties

Question 7

Gingival recession class 1 ?

Answer 7

● Recession does not extend to mucogingival junction (MGJ)
● No loss of interdental bone or soft tissue
● 100% root coverage expected after connective
tissue graft

Question 8

Gingival recession class 2 ?

Answer 8

● Recession extends to or beyond MGJ
● No loss of interdental bone or soft tissue
● 100% root coverage expected after connective tissue graft

Question 9

Gingival recession class 3?

Answer 9

● Recession extends to or beyond MGJ
● Mild/moderate interproximal bone or soft tissue loss present
● Partial root coverage expected after connective tissue

Question 10

Gingival recession class 4 ?

Answer 10

● Recession extends to or beyond MGJ
● Severe interdental bone or soft tissue loss
● No root coverage expected after connective tissue graft
