indices is the expression of clinical observations in

numerical values

indices describes the ___ of an individual or group

status

what are indices used for

assessment, clinical trials, community health epidemiologic surveys

what are the types of indices

1. calculus

2. plaque

3. gingival

4. periodontal

extensive plaque indices evaluate

all teeth

extensive plaque indices evaluate ___ or ___ surfaces on each tooth

4, 5

what is the advantage of extensive plaque indices

accuracy

what are the disadvantages of extensive plaque indices

time, correlation between home care practice and gingival condition

what are examples of extensive plaque indices

-plaque control record (O'Leary, Drake, Naylor)

-Plaque index (silness and Loe)

-Plaque free score (Grant, Stern and Everett)

modified plaque indices evaluate

only specific teeth

modified plaque indices evaluate only specific ____ on teeth

surfaces

what is the advantage of modified plaque indices

time

what are the disadvantages of modified plaque indices

1. accuracy

2. correlation between home care practice and gingival condition

what are examples of modified plaque indices

-patient hygiene performance (PHP) (podshadley and Haley)

-Simplified oral hygiene index/ OHI-S (Greene and Vermillion)

what is widely used in research

plaque index (PI I) (Silness and Loe)

with the plaque index (PI I) (Silness and Loe), all __ or ___ teeth can be evaluated

teeth, selected

___ gingival areas are examined with the plaque index (PI I) (Silness and Loe)

4

the plaque index (PI I) (Silness and Loe) can be modified to where you examine the facial, mesial and lingual surfaces and assign ___ score to mesial reading

double

what is the scoring for the plaque index (PI I) (Silness and Loe)

0-no plaque

1- a film of plaque adhering to free gingival margin and adjacent areas of tooth. May be recognized only after application of disclosing agent or by running the explorer across the tooth surface

2- moderate accumulation of soft deposits within gingival pocket that can be seen with naked eye or on tooth and gingival margin

3- abundance of soft matter within gingival pocket and/or on tooth and gingival margin

what is the evolution of plaque index (PI I) (Silness and Loe)

excellent -0

good- 0.1-0.9

fair- 1.0-1.9

poor- 2.0-3.0

the plaque free score (grant, stern, Everett) includes all teeth and __ surfaces are recorded

4

what is the evaluation of the plaque free score (grant, stern, Everett)

ideally 100% is goal

using the patient hygiene performance (PHP), what teeth and surfaces are examined

#3 facial

#8 facial

#14 facial

#19 lingual

#24 facial

#30 lingual

using the patient hygiene performance (PHP) the tooth is divided into

5 sections

using the patient hygiene performance (PHP), what is the evaluation

excellent -0

good- 0.1-1.7

fair- 1.8-3.4

poor- 3.5-5

the simplified oral health hygiene index assesses __ specific teeth one in each __

6, sextent

the simplified oral health hygiene index assesses the same tooth surfaces as the

PHP

what is the evolution of the simplified oral health hygiene index

0- excellent

0.1-0.6-good

0.7-1.8 fair

1.9-3.0 poor
