Overview :
The Gingival Index (GI) was developed by Loe and Silness to
describe the clinical severity of gingival inflammation as well as its
location.

Teeth examined:
(1) maxillary right first molar
(2) maxillary right lateral incisor
(3) maxillary left first bicuspid
(4) mandibular left first molar
(5) mandibular left lateral incisor
(6) mandibular right first bicuspid
Surfaces examined on each tooth:
(1) buccal
(2) lingual
(3) mesial
(4) distal
Gingival Index for a specific tooth =
= AVERAGE (points for the 4 surfaces)
Gingival Index for type of tooth (first molar, first
bicuspid, lateral incisor) =
= AVERAGE (Gingival Indices for the 2 teeth)
gingival index for patient =
= AVERAGE (Gingival Indices for all 6 teeth)

Interpretation |
|
2.1 -
3.0 |
severe inflammation |
|
1.1 -
2.0 |
moderate inflammation |
|
0.1 -
1.0 |
mild inflammation |
|
< 0.1 |
no inflammation |
Limitations:
• Several
subsequent modifications were made to better describe milder forms of
inflammation or to eliminate the need to perform probing.
