Study Notes
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.
