Summary

This lesson introduces periodontal disease, the tissues it affects, and how plaque-associated inflammation can damage the structures that support teeth. Understanding the process helps explain why prevention and early care matter.

Periodontal disease is a group of inflammatory conditions affecting the tissues surrounding and supporting the teeth. Its early form, gingivitis, causes gum redness, swelling, and possible bleeding. Gingivitis does not involve the attachment loss that characterizes periodontitis and can often be reversed with effective plaque control.

All flashcards

What structures make up the periodontium?
Gingiva, root cementum, alveolar bone, and periodontal ligament.
What does dysbiosis mean in periodontal disease?
Disruption of the balance of the normal oral microbial community.
How can the immune response damage periodontal tissues?
Osteoclasts can resorb bone, while matrix metalloproteinases degrade connective tissue.
What is the role of the periodontal ligament?
It connects root cementum to alveolar bone with connective-tissue fibers.
Why is smoking a periodontal risk factor?
It can impair healing and immune defenses and is linked to greater tissue loss.

Quiz questions

  1. A periodontal probing depth greater than 3 mm may indicate a pocket. What else matters when interpreting the measurement?Answer: Whether the gum attachment has migrated from its usual position.
  2. In periodontal classification, what does grading describe, in contrast to staging?Answer: The rate or risk of disease progression.
  3. Raised C-reactive protein in a person with periodontitis supports which conclusion?Answer: The conditions are associated, but this alone does not establish causation.
  4. After nonsurgical treatment, persistent deep periodontal pockets with bleeding may lead a clinician to consider what?Answer: Periodontal surgery to improve access or address supporting-tissue defects.
  5. What conclusion is supported about periodontal treatment as a method of controlling blood pressure?Answer: Evidence is insufficient to recommend it for blood-pressure control.
