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.
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 ...
According to the 2017 classification, periodontitis is divided into four stages; after considering a few factors such as: Amount and percentage bone loss radiographically; Clinical attachment loss, probing depth; Presence of furcation; Vertical bony defects; History of tooth loss related to periodontitis
Taurodontism is defined as the enlargement of pulp chambers with the furcation area being displaced toward the apex of the root of a tooth. It cannot be diagnosed clinically and requires radiographic visualization since the crown of a taurodontic tooth appears normal and its distinguishing features are present below the alveolar margin.
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]
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]
Final classification is based on the location of the splinted teeth. 1. Extra-coronal splints: Are attached to the enamel of several teeth; Use stabilising wire, fibre-optic ribbon or similar stabilisation devices to bond the outside of the teeth like a fixed orthodontic retainer. Further examples include nigh guard and tooth-bonded plastic. 2.
