Question: 1 / 1180

What class is through and through furcation involvement given?

hamp class 1

glickman class 3

glickman class 1

hamp and glickman class 3

Classifications for furcation involvement in periodontal disease are based on the level of anatomy involved and the severity of bone loss. Hamp class 1 involves incipient involvement of the furcation with less than 1/3 of bone support lost, while glickman class 1 involves minimal horizontal bone loss. Therefore, options A and C are incorrect as they do not include furcation involvement. Glickman class 3, also known as vertical bone loss, involves more than 2/3 of bone supporting the furcation being lost. However, this classification does not specify the location of the furcation involvement, making it a less likely choice. Option D, hamp and glickman class 3, combines the horizontal bone loss of hamp class 1 with the severity of glickman class 3, making it the most accurate and specific choice for through and through furcation involvement.
