Site
The Plaque Index (Silness and Löe) measure thickness of plaque at the ____ ____
Gingival margin
PI 0 =
PI 1 =
PI 2 =
PI 3 =
No plaque
Film of plaque
Moderate accumulation
Abundance of soft matter
Turesky Modification of the Quigley-Hein Index measures ____ ____ of plaque on the tooth
Surface area
TM 0 = TM 1 = TM 2 = TM 3 = TM 4 =
No plaque Flecks Thin band (up to 1mm) Thick band (>1mm) 2/3 or more of crown covered
O’Leary Plaque Control Record (used in clinic)
- Presence scored on four surfaces
- Score = (number of sites)/(number of teeth x 4)
- Goal of 20% of less (10% in hygiene clinic)
Gingival Index (Löe and Silness) GI 0 = GI 1 = GI 2 = GI 3 =
0 = Normal gingiva 1 = Mild inflammation (no bleeding on probing) 2 = Moderate inflammation (bleeding on probing) 3 = Severe inflammation (bleeding spontaneously)
Miller mobility test 0 = 1 = 2 = 3 =
0 = No detectable movement 1 = Barely detectable movement 2 = Crown moves up to 1mm 3 = Crown moves more than 1mm
