Periodontology Chapter 7 & 8

What is associated with RT 1 in the Cairo Classification System?

Which type of recession does RT 2 in the Cairo Classification System describe?

How does RT 3 differ from RT 2 in the Cairo Classification System?

What does the Cairo Classification System for recession of the gingival margin base its classifications on?

What characterizes Class IV of the Miller Classification System?

How does Class III differ from Class IV in the Miller Classification System?

Class II of the Miller Classification System indicates loss of bone or soft tissue in the interdental area.

Class I of the Miller Classification System is characterized by marginal recession that extends to MGJ.

Cairo Classification System Recession Types

RT 1: Gingival recession without interproximal attachment loss; often linked to traumatic toothbrushing.
RT 2: Gingival recession with interproximal attachment loss; commonly associated with periodontitis and horizontal bone loss.
RT 3: Similar to RT 2, but characterized by greater interproximal attachment loss compared to buccal loss and includes infrabony defects.

Cairo Classification System Overview

Utilizes clinical attachment level (CAL) measurements at both buccal and interproximal sites.
Employs objective criteria to classify the severity and extent of soft tissue recession.
Applicable in clinical practice for effective assessment.

Miller Classification System for Recession of Gingival Margin

Class I: Marginal recession not extending to the mucogingival junction (MGJ) with no interproximal bone or soft tissue loss; roots fully covered.
Class II: Marginal recession extending beyond MGJ, but with no interproximal bone or soft tissue loss; roots still completely covered.
Class III: Marginal recession extending beyond MGJ with bone and soft tissue loss in the interdental space; may prevent coverage of certain roots due to tooth malpositioning.
Class IV: Marginal recession significantly extending beyond MGJ with marked bone and soft tissue loss in interdental areas; often associated with malpositioning of teeth that hinders coverage of multiple roots.

Test your knowledge on the Cairo Classification System and recession types outlined in Chapters 7 and 8 of periodontology. This quiz explores definitions and distinctions of gingival recession and its associations. Ideal for students and professionals aiming to master periodontal concepts.
