GI+Index

= GI Index =

Gingival Index

__Purpose:__ The GI determined the severity of gingivitis based on color, consistency and BOP

__Selection of teeth and Gingival areas:__ The four areas or each tooth are examined (distal, mesial, lingal and facial). The distal for each tooth can be ommited. The score for the mesial area of the tooth is doubled, and the total score for each tooth is divided by four

__Procedure:__ 1) Dry the teeth and the gingiva throughly. 2) Use the probe to press on the gingiva to determine the degree of firmness. Examine with the mouth mirror 3) Use the probe underneath the sulcus to determine if bleeding is present as you would during MBI.

GI Code: 0= Normal gingiva 1= Mild inflammation-slight change in color, 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

Score: -GI for area of a tooth- Each individual surface (distal,mesial, facial, lingual) of each tooth is given a score from 0-3 -GI for a tooth: Scores for each area are totaled and divided by four. For example- mesial scored a 2, distal scored a 1, facial scored a 3, lingual scored a 0. 2+1+3+0= 6 4/6- =1.5 - GI for groups of teeth: Scores for individual teeth may be grouped and totaled and divided by the number of teeth. A GI may be determined for specific teeth, group of teeth, quadrant or side of mouth -GI for the individual- By totaling scores and deviding by the number examined, the GI is determined. Indices range from 0-3.

Example of a mathmatical calcultion:

Gingival index= Total score/ Number of surfaces= 35/24= 1.45

__Rating Score__ Excellent= 0 Good= 0.1-1.0 Fair= 1.1-2.0 Poor= 2.1-3.0
