Lecture on Periodontal Disease Classification

Overview

Dentists and hygienists perform a perio assessment to classify periodontal disease or condition.
Patients are categorized based on the condition of their mouth: healthy, gingivitis, periodontitis, or other conditions.
Patients can have multiple conditions simultaneously (e.g., periodontitis and peri-implant disease).
Recent changes have consolidated categories to simplify classification.

Periodontal Health or Gingival Diseases
- Healthy: No disease present.
- Gingivitis: Inflammation of the gums.
- Gingival disease non-dental biofilm-induced: Redness due to non-plaque reasons, e.g., allergic reaction to toothpaste.
Periodontitis
- Formerly divided into chronic and aggressive categories which are now combined.
- Classified by staging and grading, similar to cancer staging:
  - Staging: Reflects severity (Stage 1 to Stage 4)
  - Grading: Described as Grade A, B, or C.
Peri-Implant Diseases
- Conditions affecting tissues around dental implants.
- Can include inflammation and bone loss.
Other Conditions Affecting the Periodontium
- Includes abscesses and other specific conditions affecting oral tissues.

Reduction in Main Categories: From eight categories in 1999 to four categories currently.
Introduction of Peri-Implant Category: New classification for diseases related to dental implants.
Aggressive Periodontitis Removed: Now integrated within the overall periodontitis category.

Reflects underlying medical conditions such as diabetes.
Example: Diabetics with uncontrolled diabetes and periodontitis fall under this category.

The American Academy of Periodontology (AAP) has simplified periodontal classifications.
New system aims for consistency with the medical field by introducing staging and grading.
Understanding these categories helps in diagnosing and managing periodontal health effectively.

Further details and explanations on each category and term will be provided in subsequent videos.
