Caries Symposium Flashcards
How can we classify caries?
- Extent
- Cavitation
- Activity
- Site
- Location
Mention the classification of caries by extent
- D1 - All visually detectable lesions
- D2 - Clinically detectable cavities limited to enamel
- D3 - Lesions extending into the dentine
How to identify a cavity clinically?
Using a blunt perio probe, run it gently over the tooth - probe will catch on to cavitated surfaces
Mention the classification of caries by activity
- Active - Demineralising
- Inactive - Remineralising
Mention the classification of caries by site
- Smooth surface
- Occlusal
- Root surface
- Approximal
Mention the classification of caries by location
- Primary - de novo
- Secondary - Adjacent to restoration
How scoring system works in classifying caries?
Scoring is according to surfaces affected or tooth as a whole
What is the difference between Sensitivity & Specificity?
Sensitivity - % of disease found correctly
Specificity - % of health found correctly
What are the prerequisites for good clinical examination?
-Good light
-Dry tooth
-Take your time
-Don’t use sharp probe
Mention diagnostic tools to Improve accuracy
-ICCMS
-Magnification
-Radiographs
-FOTI (fibre-optic Transillumination).
What ICCMS stands for?
International Caries Classification and Management System - A guide on caries diagnosis
Mention the advantages & disadvantages of Radiograph
Advantages: permanent record, see between and under tooth
Disadvantages: Radiation dose
d
Advantages: Easy - utilising eye sight only
Disadvantages: Expensive, reduced field of view
