6 MOBILITY INDEX (MI) The mobility index (MI) measures the loss of bone support by indicating the amount of movement of the tooth. The length of the periodontal probe is placed on the buccal surface of the crown of the tooth and gentle pressure is applied to the tooth. The following criteria are used to assign a numerical score. 1 no mobility 2 perceptible mobility but less than 1 mm buccolingually 3 definite mobility between 1-2 mm 4 gross mobility exceeding 2 mm buccolingually and/or vertical mobility measured from the base of the pocket to the cementoenamel junction. This is a more accurate assessment of bone loss in periodontitis. PAL can be directly measured, or it can be calculated as the sum of PD plus GR. 8 FURCATION EXPOSURE In multi-rooted teeth, the area where the roots meet is referred to as the furcation. The bone loss caused by the periodontal disease often affects this area early in the disease process. The presence of furcation involvement should be evaluated and recorded as Grade 0 – 3 depending upon the amount of involvement. 7 PERIODONTAL ATTACHMENT LEVEL (PAL) In the PAL, the pocket depth is
9 STAGE OF PERIODONTAL DISEASE
10 ORAL MASSES Oral masses need to be drawn onto the chart and noted. This includes epuli and gingival hyperplasia. This is important to note these in order to have a record of the mass and be able to note changes in future examinations as well as gingivectomies (the removal of excess gingival tissues).
The stages of periodontal disease can be used to help price your periodontal therapies but also need to be recorded so that the progression of the disease can be determined. These stages are determined by either measuring clinical attachment level or radiographically. Stage 1 - Gingivitis only with attachment loss. Stage 2 - Less than 25% attachment loss. Grade 1 furcations present. Stage 3 - 25 to 50% attachment loss. Grade 2 furcations present Stage 4 - Over 50% attachment loss. Grade 3 furcations present.
