Incipient furcation involvement is known as?

1. glickman class 4

2. glickman class 2

3. glickman class 1

4. hamp class 1

The correct answer is: glickman class 1

Incipient furcation involvement is the initial stage of furcation involvement, where there is a loss of bone support between the roots of a tooth. This is also referred to as a furcation lesion. Glickman class 1 describes furcation involvement in the early stages and there is still a high chance of success with treatment. Glickman class 2, on the other hand, refers to moderate furcation involvement with more significant bone loss and decreased chances of success with treatment. Glickman class 4 describes extensive furcation involvement where the roots are almost completely separated, and the tooth is at high risk of extraction. Lastly, Hamm class 1 is not applicable to furcation involvement and refers to an occlusal carious lesion affecting the pit and fissure of a tooth. Therefore, the most appropriate answer for this question is C Glickman class 1.
