Indices in Dentistry

1.      An index measuring the periodontal disease of an individual is classified under:

• Composite index

• Cumulative index

• Reversible index

• Symptom index

An example for the reversible index— where scores can decrease or increase on subsequent examinations is:

• Periodontal index

       

• Dental caries index

• Root caries index

      

• Plaque index

Third molars are not recorded in Oral Hygiene Index (OHI) because of:

• Inconvenience

•   Wide variations in the height of the clinical crown

• Absent most of the times

• Simplicity

1.      The upper limit for the OHI – S index is:

•      6

• 12

•    18

• 24

    The Plaque Index measures the thickness of plaque at the:

• Incisal third

      

• Middle third

      

• Gingival third

       

• Occlusal portion

1.      Which of the indices measures extent of bleeding from sulcus in perio problems?

a.     

• Silness and Loe index  

•    Loe and silness index

• Muhlemann

      

• Navy plaque index

1.      Which instrument is used to record the Gingival Bleeding Index?

• Straight probe

• Unwaxed dental floss

• Explorer

• CPI- C probe

  An index measures the disease in terms of:

• Qualitative

       

• Quantitative

• Cumulative

• Facultative

The term reproducibility is synonymous with:

•   Clarity

• Validity

•   Reliability

• Quantifiability

  Sensitivity and specificity are the components of:

• Validity

• Validity

• Acceptability

•     Precision
