What does cul-de-sac furcation involvement refer to?

  1. glickman class 4

  2. glickman class 2

  3. glickman class 1

  4. hamp class 2

The correct answer is: glickman class 2

Cul-de-sac furcation involvement refers to Glickman Class 2. In this classification system, Glickman Class 2 furcation involvement is described as a "cul-de-sac" or a pocket that extends into the furcation but does not pass through the entire furcation area. This is different from Glickman Class 1 where there is initial involvement of the furcation, but the lesion does not proceed into the furcation area, and Glickman Class 4 where there is through-and-through furcation involvement. Hamp Class 2 refers to a different classification system for furcation involvement and is not related to cul-de-sac furcation involvement as described in Glickman Class 2.
