Q

What is the difference between gingivitis and periodontitis?

A

Gingivitis is reversible and periodontitis is not.

2
Q

What clinically can be seen in gingivitis?

A

Inflammation

Deep periodontal pockets

3
Q

What can be seen clinically in periodontitis?

A
Inflammation
Migration of epithelial attachment 
Destruction of periodontal ligament
Destruction of bone
Recession
True pockets
Bleeding
4
Q

What are the 3 main damaging products that bacteria produce?

A
  1. Metabolic products (highly acidic)
  2. Enzymes (proteases to break down connective tissue)
  3. Toxins (damage immune cells)
5
Q

What is the host response to bacteria?

A

Inflammation
Innate and adaptive
Removal of damaged tissues / repair

6
Q

What is the gingivitis not found in the crevicular fluid?

A

Immune cells here

7
Q

What is occurring between the bacteria and the host in gingivitis?

A
  • Natural biofilm
  • Organised microbial community
  • Composition depends on environment
  • Coordinated response to plaque
  • Protective response
8
Q

What happens when periodontitis progresses?

A
Mature plaque
Pathogenic species
Effective inflammatory response 
Local host response unbalanced
Loss of periodontal support
9
Q

What is the definition fo a bacterial virulence factor?

A

Products of a pathogenic organism essential for development of disease.
Mya have direct damage to host or indirect via inflammatory response.

10
Q

What pathogen is associated with periodontitis?

A

P gingivalis

11
Q

Give some host risk factors

A
Genetics
Age 
Stress
Smoking
Systemic conditions e.g. diabetes
12
Q

How can we treat periodontal diseases?

A

1) Prevent plaque from maturing (teach OHI)
2) Remove mature plaque (scaling needed)
3) Anti-septic mouthwashes
4) Antibiotics (when bacteria are multiplying in tissue)
