Periodontics Bootcamp Quiz

Periodontal Health

• A healthy periodontium is characterized by the absence or presence of up to two sites of clinically detectable inflammation, minimal or no bleeding on probing, and normal probing depths (≤3 mm).
• The periodontium can be intact (no attachment or bone loss) or reduced (previous attachment or bone loss).

Gingivitis

• Gingivitis is characterized by inflammation, erythema, edema, bleeding on probing, and normal probing depths (≤3 mm).
• The periodontium is stable with no current progressive attachment or bone loss.

Periodontitis

• Periodontitis is characterized by loss of periodontal support due to microbial-associated, host-mediated inflammation.
• It is marked by deeper probing depths (≥4 mm) and presence of interproximal attachment loss from the current disease state.
• This does not include attachment loss from a history of disease in currently stable patients.

Periodontal Staging

Stage I

• Characterized by 1-2 mm greatest interdental clinical attachment loss.
• Less than 10% bone loss.

Stage II

• Characterized by 3-4 mm greatest interdental clinical attachment loss.
• 10-20% bone loss.

Stage III

• Characterized by 4-5 mm greatest interdental clinical attachment loss.
• 20-30% bone loss.

Stage IV

• Characterized by ≥5 mm greatest interdental clinical attachment loss.
• More than 30% bone loss.
