Glickman class 4 describes?

  1. through and through furcation

  2. incipient furcation involvement

  3. through and through furcation + ability to see through it

  4. cul-de-sac furcation involvement

The correct answer is: through and through furcation + ability to see through it

Glickman Class 4 describes a through and through furcation that allows the examiner to see through it. This class of furcation involvement represents a severe condition where there is complete loss of bone and soft tissue in the furcation area, resulting in a communication between the buccal and lingual/palatal aspects of the tooth. This extensive involvement is typically associated with poor prognosis and significant challenge in treatment planning. Therefore, the correct answer is C, as it accurately describes the characteristics of Glickman Class 4 furcation involvement.
