Chronic Periodontitis

Question 1

What is the definition of periodontits?

Answer 1

Loss of attachment and bone

Starts as plaque induced gingivitis

Question 2

What are the characteristics of chronic periodontitis?

Answer 2

• Most prevalent in adults
• Destruction consistent with presence of local factors.
• Subgingival calculus frequent
• Slow to moderate progression, but can have periods of rapid.

Question 3

What are the classifications of chronic periodontitis? (Localized and General. Slight, Moderate, and Severe).

Answer 3

Localized: Less than 30% of teeth
Generalized: More than 30% 
Slight: 12 mm Clinical Attachement Loss (CAL)
Moderate: 3-4 mm CAL
Severe: >=5 mm CAL

Question 4

What is the biggest etiology for getting chronic periodontitis? How does it progress?

Answer 4

Inflammation!

Progresses in an asynchronous model

Question 5

What is treatment of Chronic periodontitis?

Answer 5

• Preventing formation/eradication of plaque.
• Removal of sub and supra gingival plaque.
• OHI very important!

Question 6

What is the definition of Aggressive periodontitis?

Answer 6

• Rare, Severe, rapidly progressing
• Often characterized by early age of manifestation.
• Except for periodontitis, patient otherwise healthy.
• Familial aggregation

Question 7

What are some secondary features of aggressive periodontitis?

Answer 7

• Amounts of microbial deposits are inconsistent with severity of tissue destruction.
• Phagocyte abnormalities.
• Progression of attachment loss and bone may be self-arresting.

Question 8

What is the classification of localized aggressive periodontitis?

Answer 8

• Circumpubertal onset
• robust serum antibody response to infecting agents.
• Localized First molar/incisor presentation with interproximal attachment loss on at least two permanent teeth.

Question 9

What is the classification of generalized aggressive periodontitis?

Answer 9

• Usually affecting persons under 30 yrs.
• Poor serum antibody response
• Pronounced episodic nature of destruction of attachment and alveolar bone.
• Generalized interproximal attachment loss affecting at least 3 permanent teeth other than first molars and incisors.

Question 10

What is important regarding AA?

Answer 10

Has a toxin that kills leukocytes and they are capable of invading into the tissue.

Question 11

What increased titres of antibodies may be protective in preventing localized aggressive to generalized.

Answer 11

IgG2.
