Loading flashcards...
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
