DISEASE CONTROL PROGRAM NOTES
A.
GINGIVAL BLEEDING INDEX (GBI)
STEP 1. Explain procedure to patient.
STEP 2. Floss the mesial and distal surfaces of teeth numbers 3, 8, 14, 19, 24, and
30.
NOTE:
The floss should be inserted with gentle back and forth motion (sawing type
motion) with the fingers touching the teeth. This will prevent the floss from
snapping through the contact and possibly injuring the gingiva.
STEP 3. Floss each surface to the depth of the gingival sulcus and observe for 15
seconds.
STEP 4. Scoring.
a. No bleeding observed--score - 0.
b. Bleeding observed--score - 1.
STEP 5. Record the bleeding score on
chart above the root of
surface tested.
Maximum Gingval Bleeding index (GBI) for each tooth is two.
(Maximum GBI for the six teeth is 12.)
B.
PLAQUE INDEX
STEP 1. Explain procedure to patient.
STEP 2. Stain patient's teeth using a disclosing tablet.
STEP 3. Use the facial surfaces of teeth numbers 3, 8, 14, and 24, and the lingual
surfaces of teeth 19 and 30 to obtain plaque index. If these teeth are
missing, use adjacent teeth.
STEP 4. Scoring.
a. Mentally divide the surface into thirds vertically.
b. Dental plaque in any one section scores 1.
c. Maximum score for any one tooth is 3.
STEP 5. Record tooth number and score. Multiply by six to obtain the score.
