In the Cairo Classification, which type of recession indicates that interproximal CAL loss is less than or equal to buccal CAL loss?

In the Cairo Classification of recession types, the classification is specifically designed to categorize the relationship between buccal and interproximal clinical attachment loss (CAL). The type referred to in this case is characterized by the condition where interproximal CAL loss is equal to or less than the buccal CAL loss. This particular relationship indicates that there is no significant loss of tissue interproximally compared to the buccal aspect.

The RT2 type fits this description perfectly as it signifies a situation where the interproximal attachment loss is equivalent to or less than the buccal loss, suggesting that the recession at the affected site may not be as extensive in terms of surrounding interdental papillae or bone loss. Understanding this classification is crucial for clinicians to plan appropriate periodontal treatment and predict outcomes effectively.
