Quiz 4. Indices Flashcards
What are the oral hygiene status indices?
Plaque Index (PLI) Plaque-Control Record Plaque-Free Score Patient Hygiene Preformance (PHP) Simplified Oral Hygiene Index (OHI-S)
What is measured on PLI?
Biolfilm at gingival margins
How many teeth/surfaces are scored for PLI?
Four areas on all teeth or selected teeth
Reference Scales for PLI
Disclosing agent used it necessary
Rating Good: 0.1-1.7
Fair 1.0-1.9
Poor 2.1-3.0
What is measured with plaque-control record?
Biofilm
How many teeth/surfaces are scored for plaque-control record?
Four or six surfaces on all teeth
How do you measure for plaque-control record?
Presence or absence of biofilm
Reference scale for plaque-control record?
Range from 0-100%
100% means poor
Disclosing used
What is measured for plaque-free score?
Biofilm-free surfaces
How many teeth/surfaces are measured for plaque free score?
Four surfaces on all teeth
How do you measure for plaque-free score?
Presence or absence of biofilm
Reference Scale for plaque-free score?
0-100%
100% being excellent
Disclosing agent used
What is measured on PHP ?
Debris
How many teeth/surfaces are measured PHP?
Six teeth 3 +8
14 + 24 (facial)
19 + 30 (lingual)
How do you measured PHP?
Each tooth divided into 5 segments
0= no debris
1= debris
Reference scale for PHP
Scores ranging from 0-5
What is measured on GI
Bleeding, color
Reference scale for GI
Circumferential probing motion
Scores from 0-3
What does (OHI-S) measure?
Debris and calculus
How many teeth/surfaces are measured in (OHI-S)?
Six teeth 3 + 8
14 + 24 facial
19 + 30 lingual
How do you measure OHI-S?
1= less than 1/3 of tooth surface 2= 1-2/3 of tooth surface 3= greater than 2/3 of tooth surface
Reference scale of OHI-S
DI range from 0-3
CI range from 0-3
Total range from 0-6

Sulcus Bleeding Index (SBI)
Gingival Bleeding Index (GBI)
Eastman Interdental Bleeding Index (EIBI)
Gingival Index (GI)
What is measured for SBI?
Bleeding, color, swelling
How many teeth/surfaces are measured in SBI?
Four gingival areas on each tooth
How do you measure SBI?
0,1,2,3,4 (1), 4 (2), 5
