Q

T or F, In many cases in which gingival diseases are modified by systemic factors, the signs of inflammation are only present when large amounts of bacteria are found in the plaque.

A

False, They are present with relatively little amounts of bacterial plaque (in many of the cases, but not necessarily all).
**Controlling the systemic factors becomes more important than controlling bacterial plaque

Q

Describe the differences between Localized Aggressive Periodontitis and Generalized Aggressive Periodontitis

A

Localized:

  • patient exhibits a strong serum antibody response to the infecting agents.
  • Excellent prognosis!! It can be cured

Generalized:

  • Patient exhibits a poor antibody response to infecting agents.
  • Patients do not respond well to conventional periodontal therapy.
  • Use of systemic antibiotics should be considered to help control disease.
