What Hamp classification is given to horizontal furcation involvement <3mm?

  1. hamp class 1

  2. hamp class 2

  3. glickman class 1

  4. glickman class 2

The correct answer is: hamp class 1

Hamp classification refers to the severity of furcation involvement, specifically in terms of horizontal involvement. Class 1 refers to furcation involvement of less than 3mm, making it the correct answer in this scenario. B, C, and D are incorrect because they refer to Glickman classification, which categorizes furcation involvement based on the degree of horizontal and vertical involvement. Glickman class 1 refers to less than 1/3 of the root involved, while Glickman class 2 refers to 1/3 to 2/3 of the root involved. Neither of these options are specific to horizontal involvement of less than 3mm, making A the most appropriate choice.
