In 1953, Irving Glickman graded furcation involvement into the following four classes: [3] Grade I - Incipient furcation involvement, with an associated periodontal pocket remaining coronal to the alveolar bone. The pocket primarily affects the soft tissue. Early bone loss may have occurred but is rarely evident radiographically.
A new classification has been proposed to classify gingival and palatal recessions. The new classification system gives a comprehensive depiction of recession defect that can be used to include cases that cannot be classified according to earlier classifications. A separate classification system for palatal recessions (PR) is also proposed.
The assessment of furcation involvement is performed using a specialized curved instrument called the Nabers probe, which is used to detect horizontal concavities on the root surface where the roots diverge. [3] [4] The severity of furcation involvement is categorized using the Glickman Classification system, which includes four grades: [3]
The pink arrow, on the right, points to a furcation involvement, or the loss of enough bone to reveal the location at which the individual roots of a molar begin to branch from the single root trunk; this is a sign of advanced periodontal disease.
However, if the opening of a periodontal pocket becomes obstructed, as may occur if the pocket has become very deep (e.g. with furcation involvement), then plaque and calculus are trapped inside. [12] Food impaction may also obstruct a periodontal pocket. [13]

In the 1950s, Glickman developed the bone factor concept about the factors that determine the severity of periodontal destruction, [3] and developed a classification system for furcation involvement [4] In 1965, Glickman proposed a theory involving the relation of occlusal trauma to periodontal disease which led to further research in animal ...
