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.
