GI+Index

The gingival index is a method for assessing the severity and quantity of gingival inflammation in individual patients or a large populations. This index only assesses the the gingival tissues. The gingival tissues surrounding each tooth the facial, mesial, distal, and lingual are assessed for inflammation and given a score of 0-3. Bleeding is assessed by running a periodontal probe along the soft tissue wall of the gingival pocket. The scores for the four areas are then added after adding them they are then divided by four to get the tooth score. The tooth scores are then added and divided by the number of teeth examined to calculate the patient's gingival score. The gingival index can be performed on selected teeth or all teeth. A GI score of O.1 to 1.0 indicates mild inflammation, 1.1 to 2.0 indicates moderate inflammation, and 2.1 to 3.0 indicates severe inflammation. This index measures the severity of inflammation and is reversible.

 * Gingival scores:**
 * 0= normal gingiva**
 * 1=mild inflammation: slight change in color and slight edema; no bleeding on probing**
 * 2=moderate inflammation: redness, edema, and glazing; bleeding on probing**
 * 3=severe inflammation: marked redness and edema; ulceration; tendency to spontaneous bleeding**
 * Gingival Index scores:**
 * 0.1-1.0: indicates mild inflammation**
 * 1.1-2.0: indicates moderate inflammation**
 * 2.1-3.0: indicates severe inflammation**
