Intro to Perio: ADA Periodontal Disease

Questions and Answers

What is periodontal disease?

Any group of inflammatory and microbial infections diseases affecting the gingiva and supporting teeth; consists of gingivitis and periodontitis.

What is the difference between gingivitis and periodontitis?

Gingivitis is the inflammation of the gingival tissues (does not involve attachment apparatus), while periodontitis is an inflammatory disease of the supporting tissues of the teeth.

What causes pocket depths to increase? (Select all that apply)

Deep cleaning

Pseudopockets (correct)

Periodontal pockets (correct)

Dental caries

What is a pseudopocket?

Not associated with bone loss; only tissue enlargement with a deepened sulcus due to increased bulk of gingiva. Signup and view all the answers

What characterizes a periodontal pocket?

Study Notes

Periodontal Disease Overview

Periodontal disease includes inflammatory and microbial infections affecting the gingiva and supporting teeth, comprising gingivitis and periodontitis.

Gingivitis vs. Periodontitis

Gingivitis: Inflammation of gingival tissues; does not affect attachment apparatus.
Periodontitis: Inflammatory disease involving supportive tissues of teeth, resulting in attachment loss.

Causes of Pocket Depth Increase

Pocket depth can increase due to pseudopockets or periodontal pockets.

Pseudopocket

Characterized by tissue enlargement without bone loss.
Sulcus deepens due to increased bulk of gingiva.

Periodontal Pocket

Associated with tissue destruction and bone loss.
Divided into suprabony and infrabony pockets.

Suprabony vs. Infrabony Pockets

Suprabony Pockets: Base is coronal to the alveolar bone crest; typically results from horizontal bone loss.
Infrabony Pockets: Base is located below the alveolar bone crest; indicates vertical bone loss.

ADA Disease Classifications

ADA I: Gingivitis
ADA II: Early Periodontitis
ADA III: Moderate Periodontitis
ADA IV: Advanced Periodontitis

ADA Case Type I: Gingivitis

Alveolar crest positioned 1-2mm from CEJ.
Probing depth ranges from 1-3mm.
No bone loss or clinical attachment loss; variations classified as early, moderate, and severe.

ADA Case Type II: Early Periodontitis

Alveolar crest 3-4mm from CEJ.
Probing depth approximately 4mm.
Horizontal bone loss; clinical attachment loss of 1-2mm.

ADA Case Type III: Moderate Periodontitis

Alveolar crest 5-6mm from CEJ.
Probing depth between 5-6mm.
Presence of bone loss; clinical attachment loss of 3-4mm.

Attachment Level for Recession

Attachment level is calculated by summing the probing depth and the measurement of recession.

ADA Case Type IV: Advanced Periodontitis

Alveolar crest is 7mm or more from CEJ.
Probing depths of 7mm or greater.
Significant bone loss and clinical attachment loss of 5mm or more.
