In Class 2 furcation involvement, how far does the probe enter?

• A. Less than 1mm
• B. More than 1mm, but not completely through
• C. Completely through the furcation
• D. Can be seen clinically due to recession

Answer: (B)

In Class 2 furcation involvement, the probe penetrates more than 1mm into the furcation area but does not completely pass through. This classification indicates that there is significant loss of interradicular bone, allowing for some probing depth without full communication between the roots. Class 2 furcation involvement is characterized by a pocket that is accessible to the probe, revealing the furcation area, which signals the clinician that the periodontal disease has advanced to a point where surgical intervention may be necessary. This understanding is crucial for developing appropriate treatment plans for patients with periodontal disease.
