Study Notes
Furcation Involvement
- Refers to bone resorption seen in the bifurcation or trifurcation areas of multi-rooted teeth due to periodontal disease.
Subclass A
- Defined by a probeable depth of 0-3 mm from the roof of the furcation.
Subclass B
- Characterized by a probeable depth of 4-6 mm from the roof of the furcation.
Subclass C
- Indicates a probeable depth of 7 mm or greater from the roof of the furcation.
Modified Hamp Index
- A classification system that describes degrees 1-4 of furcation involvement based on horizontal bone loss and probeability.
Degree 1
- Indicates less than 3 mm horizontal loss of periodontal tissue support.
Degree 2
- Represents horizontal loss of support that exceeds 3 mm but does not involve the total width of the furcation area.
Degree 3
- Describes complete horizontal destruction of periodontal tissue in the furcation area.
Degree 4
- Indicates a furcation that is visible through and through, highlighting severe loss.
Glickman Classification
- A classification for furcation involvement that focuses on the horizontal component of bone loss, including a radiological aspect.
Grade I
- Considered incipient or early stage; affects soft tissue and usually shows no radiographic changes.
Grade II
- Can affect multiple furcations of a tooth; shows a definite horizontal component, where furcations do not communicate, and potential vertical bone loss.
Grade III
- Describes total through and through furcation involvement; can be identified with appropriately exposed radiographs.
Grade IV
- Indicates a clinically visible furcation opening, signifying advanced periodontal involvement.
Tarnow
- Developed a vertical classification system to enhance the Modified Hamp or Glickman Classification systems.

Description
This quiz explores the concept of furcation involvement in multi-rooted teeth as related to periodontal disease. It covers the different subclasses based on probeable depths and the Modified Hamp Index that categorizes degrees of furcation involvement. Test your understanding of these critical dental classifications and the implications for periodontal treatment.
