Examination And Tx Plan

Probing Depth (PD): measured clinically as the distance between gingival margin and base of the pocket

Bleeding on probing (BOP): bleeding from the sulcus/pocket that occurs following probing. Recorded as present or absent. Suppuration: presence of pus in the periodontal pocket. Gingival recession is measured as the distance between CEJ and gingival margin.

Clinical attachment level (CAL): “when the gingival margin is on the anatomic crown, CAL is determined by subtracting from the depth of the pocket the distance from the gingival margin to the cemento-enamel junction (CEJ)…when the gingival margin coincides with the CEJ, the loss of attachment equals the pocket depth. When the gingival margin is located apical to the CEJ,...the distance between the CEJ and the gingival margin should be added to the probing depth.”

Keratinized gingiva is the distance between Mucogingival junction and the gingival margin. The width of the attached gingiva is “the distance between Mucogingival junction and … the external surface of the bottom of the gingival junction.” This means that the attached gingiva is calculated by subtracting the PD from the keratinized gingiva.

Mobility: teeth that have more than physiological mobility. Methods to measure mobility: a) two instruments b) one instrument and one finger

Miller (1950) Mobility index: Class I: first distinguishable sign of movement greater than “normal”;

Class II: movement of the crown up to 1 mm in any direction; Class III: movement of the crown more than 1 mm in any direction and/or vertical depression or rotation of the crown in its socket Fremitus: palpable or visible movement of the tooth when subjected to occlusal forces.

Furcation Invasion: pathological resorption of bone within a furcation.

Hamp et al. (1975) classification of furcation invasion: Grade I: horizontal furcation invasion less than 3mm; Grade II: horizontal furcation invasion more than 3mm but not encompassing the total width of the furcation; Grade III: horizontal through-and-through furcation invasion.
