1

What is accuracy

Measures what is claimed

2

What is precision

Consistency of measurement

3

Describe sensitivity and specificity within accuracy

Sensitivity - % of disease found correctly
Specificity - % of health found correctly

4

What is the accuracy of detecting D1 caries under normal examination

Sensitivity - 0.32
Specificity - 0.97

5

What is the accuracy of detecting D3 caries under normal examination

Sensitivity - 0.34
Specificity - 0.99

6

How can accuracy of caries diagnosis be improved

ICCMS
Radiographs
Magnification
FOTI

7

What is ICCMS

International Caries Classification and Management System
A set of clinical protocols that address all diagnostic, preventative and restorative decisions necessary to preserve tooth structure and restore only when indicated

8

What is the accuracy of detecting D1 caries under ICCMS examination

Sensitivity - 0.65
Specificity - 0.85

9

What is the accuracy of detecting D3 caries under ICCMS examination

Sensitivity - 0.8
Specificity - 0.8

10

How does ICCMS examination compare to normal examination

Higher sensitivity but lower specificity
Better way of diagnosing caries especially if looking at secondary prevention methods

11

What are the advantages of taking radiographs

All practices have the capability
Quick
Permanent

12

What are the disadvantages of taking radiographs

Uses ionising radiation
Difficult to standardise angle
If taken from a different angle you may not be able to track the progression of a lesion accurately over time

13

What is the accuracy of detecting D1 approximal caries using bitewing radiographs

Sensitivity - 0.32
Specificity - 0.87

14

What is the accuracy of detecting D3 approximal caries using bitewing radiographs

Sensitivity - 0.57
Specificity - 0.95

15

What are the advantages of magnification

Simple technique
Allows better view

16

What are the disadvantages of magnification

Takes time to get used to
High cost of at least £1,000

17

What is the accuracy of detecting D1 caries with magnification

Sensitivity - 0.42
Specificity - 0.94

18

What is the accuracy of detecting D3 caries using magnification

Sensitivity - 0.37
Specificity - 0.99

19

What other techniques can be used for caries diagnosis

Fibre-optic transillumination - shining a light through the tooth, caries stops the light and you see shading
DIAGNOdent
Electric techniques
