Indicies Flashcards
An index that combines a debris score and a calculus score using specific surfaces of six teeth
OHI-S
A determination of accuracy and consistency between examiners; affects the reliability of data collection
calibration
An index that measures conditions that are not able to be changed; in other words, evidence of the condition will remain even after treatment; example is dental caries
irreversible
Periodontal screening index used for community oral health surveillance that can be used in conjunction with a code related to loss of attachment
CPI
Index that measures fluorosis using six categories
Dean’s
A sweeping motion of the dental probe determines bleeding evaluation when this index is used
Gingival Index (GI)
Ramfjord teeth #’s
3, 9, 12, 19, 25, 28
Type of index that measures all the evidence of a condition past and present`
Cumulative
Total number of cases of some disease or condition in a given population
prevalence
Index used to assess thickness of dental biofilm at gingival area
Plaque index (PL I)
Index uses unwaxed dental floss to determine areas of interproximal gingival bleeding
GBI
Refers to a brief initial exam for an individual or an assessment of many individuals to determine a certain characteristic in a population
screening
Type of index that measures a condition that can be changed and no evidence of the condition will remain; example is dental biofilm
reversible
An expression of clinical observations in numerical values
index
A factor that is measured and analyzed to describe health status
indicator
Refers to the number of new cases of a disease that occur during a certain period of time
incidence
Systematic collection of oral health data for use in planning public health programs
Surveillance
Category of indices that measures the only presence or absence of a condition
simple
Measures what it is intended to measure
valid
Consistency of measurement; enhanced by calibration of examiners
Reliability
Index uses triangular wooden interdental cleaner to identify areas of interproximal bleeding
eastman
Index used to determine caries experience
DMF
Index similar to the community periodontal index that is used to screen individual patients in a private practice
PSR
To record the presence of dental biofilm on individual tooth surfaces to permit the patient to visualize progress while learning biofilm control
Plaque Control Record
To determine the location, number and percentage of biofilm-free surfaces for individual motivation and instruction
Plaque-Free Score
To assess the extent of biofilm and debris over a tooth surface; debris is defined as the soft foreign material consisting of dental biofilm, material alba, and food debris that is loosely attached to the tooth
Patient Hygiene Performance (PHP)
To assess oral cleanliness by estimating the tooth surfaces covered with debris and/or calculus
OHI-S
OHI-S combines
DI-S and CI-S
DI-S Score 0
No debris or stain present
DI-S score 1
Soft debris covering not covering more than 1/3 of the tooth surface being examined, or the presence of extrinsic stains without debris, regardless of surface area covered
DI-S score 2
Soft debris covering more than 1/3 but not more than 2/3 of exposed tooth surface
DI-S score 3
Soft debris covering more than 2/3 of exposed tooth surface
CI-S Score 0
No calculus present
CI-S Score 1
Supragingival calculus covering not more than 1/3 of exposed tooth surface being examined
CI-S Score 2
Supragingival calculus covering more than 1/3 but not more than 2/3 of exposed tooth surface, or the presence of individual flecks of subgingival calculus around the cervical portion of the tooth
CI-S Score 3
Supragingival calculus covering more than 2/3 of exposed tooth surface or a continuous heavy band of subgingival calculus around the cervical portion of the tooth
Individual DI-S and CI-S rating and score 0
excellent
Individual DI-S and CI-S rating and score .1-.6
good
Individual DI-S and CI-S rating and score .7-1.8
fair
Individual DI-S and CI-S rating and score 1.9-3
poor
OHI-S score and rating score 0
excellent
OHI-S score and rating score .1-1.2
good
OHI-S score and rating score 1.3-3.0
fair
OHI-S score and rating score 3.1-6
poor
To assess the state of periodontal health of an individual patient
Periodontal Screening and Recording (PSR)
PSR is a modified form of
The original CPITN index
Screen and monitor the periodontal status of populations
Community Periodontal Index (CPI)
PSR code 0
Band visible, no calculus or bleeding
PSR code 1
Band visible, pleading present, no calculus
PSR code 2
Band visible, calculus present, bleeding may or may not be present, or defective restoration margins
PSR code 3
Band partially visible, calculus, defective restorations, bleeding may or may not be present
PSR code 4
Band completely hidden, calculus and bleeding doesn’t matter
Locate areas of gingival sulcus bleeding and color changes to recognize presence of early gingival disease
Sulcus Bleeding Index (SBI)
To record presence or absence of gingival inflammation as determined by bleeding from interproximal gingival sulci
Gingival Bleeding Index (GBI)
To assess severity of gingivitis based on color, consistency, and bleeding on probing
Gingival Index (GI)
GI code 0
normal gingiva
GI code 1
Mild inflammation-slight change in color, slight edema. No BOP
GI code 2
Moderate inflammation-redness, edema, and glazing. BOP
GI code 3
Severe inflammation-marked redness and edema. Ulceration. Tendency to spontaneous bleeding
GI score 0
excellent (healthy tissue)
GI score .1-1.0
good
GI score 1.1-2.0
fair
GI score 2.1-3
poor
To determine total caries experience past and present by recording number of affected teeth
DMFT
How to score individual DMF
D+M+F=DMF
How to calculate group DMF
Total the DMFs for each individual examined
Divide the total DMFs by number of individual in group
How to find GI for a tooth
Scores for each area totaled and divided by 4
GI for individual
Scores added and divided by # of teeth examined
GI for a group
Add individual GI scores and divide by # of individuals examined
