If there is a problem what must should they be referred to ?
Comp exam
What is oral health surveillance used for ?
To describe oral health of a community rather than an individual
If something measures what it is untended to measure it is what..?
Valid
If something is consistent, stable, and reproducible then it is what?
Reliable
Indices should be what?
- Valid
- Reliable
- Easy to utilize
- Sensitive
- Acceptable
- Quantifiable
- Clinically significant
The ability of different examiners to get the same score on the same person being examined is known as what?
Interexaminer reliability
The ability of the same examiner to get the same score twice on the same person being examined is known as what?
Intraexaminer
What is necessary to ensure reliability/accuracy?
Training and calibration
What do simple indices measure?
Only presence or absence of a condition
The index that measure all past and present evidence of a condition is what?
Cumulative index
The index that measure conditions that can be reversed is what ?
Reversible index
What index measures cumulative conditions that cannot be revered?
Irreversible index
Teeth #3, 9, 12, 19, 25, and 28 are known as what?
Ramfjord teeth - only teeth that are screened
What are the common types of dental indices?
- Plaque and calculus accumulation
- Gingival health
- Periodontal health
- Dental caries
- Dental fluorosis
- Orthodontic need
How is the coronal caries index for permanent teeth used?
DMF index (decayed, missing, filled) - measures disease severity and prevalence
How is the coronal caries index for primary teeth used?
Same as permanent teeth but with primary teeth
How is the root caries index (RCI) measured?
Adds root surfaces that are deceased or filled then dividing by the total number of teeth with recession (expressed as a percentage, Dows not take into account missing teeth)
The index that assesses extent of plaque and debris on F of maxilla and L of mandible by applying disclosing agent (divide each tooth into 5, 2 inter proximal and cervical, middle, coronal) is known as what?
Patient Hygiene Performance (PHP)
True/false the patient hygiene performance modified index is the same as the patient hygiene performance except on only Ramfjord teeth
True
What index is measured by applying disclosing agent, examining gingival margin for plaque and records number of surfaces with retained plaque and divide by total number of surfaces?
Plaque Control Record (PCR)
What index is measured by applying disclosing agent, counting the number of surfaces with plaque, and multiplying the total number of teeth by 4 and subtracting the number of surfaces with plaque for a plaque free score?
Plaque free score
What index scores 4 surfaces on a scale of 0-3 based on thickness, adds scores for all teeth and divides by number of teeth assessed?
Plaque index (PI)
What index evals supra and sub plaque on 1 tooth with the most per sextant, add all scores and dived by number of sextant?
Simplified oral hygiene index (OHI-S)
What index records the presence/absence of inflammation and delayed bleeding/bleeding using floss?
Gingival bleeding index (GBI)
What index measures bleeding by probing 4 sites (waiting 30 sec), divide sum of all sites by f4?
Sulcular bleeding index (SBI)
What index measures bleeding while using a wooden interdental cleaner that is placed horizontally between teeth, dividing sum of IP spaces that bled by total of IP spaces evaluated?
Eastman interdental bleeding index (EIBI)
What index measure periodontal status of a community using a ball probe but is somewhat expensive and extensive?
Community periodontal index (CPI)
What index uses a probe to "sweep" around the tooth, four sites are scored 0-3?
Gingival index (GI)
How is scoring of loss of attachment (LOA) measured?
Measured like normal then put in an ordinal scale suggested by WHO
What index is designed to be used Gi and scores 4 surfaces on scale 0-3 based on thickness of plaque at gingival margin?
Plaque index (PII)
What index scores the worst between 2 teeth for dental fluorosis, and is less time consuming recommended by WHO?
Deans fluorosis index
What index gives a score to each tooth surface in the mouth for fluorosis, provides comp info on amount and distribution of fluorosis?
Tooth surface index of fluorosis (TSIF)
True/false measuring oral and pharyngeal cancers are expressed as rate or proportion
True
