Standard Techniques for Carious Lesion Detection Flashcards
What % is enamel inorganic mineral by weight?
96%
Waht are the standard techniques for caries detection?
- Visual, including transillumination
- Tactile
- Radiographic
- Other
Describe caries into enamel
Net demineralisation leading to progressive dissolution of enamel crystals
Describe caries into dentine
Acid demineralisation of the inorganic component and proteolytic degradation of organic phase
Describe a visual examination
Visually observing all surfaces of the tooth that you can see.
have a system.
- check plaque covered
- check clean wet
- check clean dry
What are the optical properties of
water, enamel, air, dentine?
Dentine is more translucent than enamel.
Water: 1.3
Enamel: 1.6
Air: 1.0
Dentine: 1.5
What is the Maillard reaction?
a browning reaction
That is the spectrum of dentine hardness?
Sleepy Leamurs Forget Hygiene
What is frank cavitation?
clearly visible cavitation into dentine
What type of lighting is best for caries detection?
Standard lighting
Where is tactile examination indicated?
Where visual examination is impossible.
(approximal, root)
What are we feeling for in a tactile examination?
roughness, softness, cavitation
Where is tactile examination contraindicated?
pits and fissures
Where are bitewings indicated?
posterior contacting approximal surfaces where direct vision is obscured.
as a safety net for occlusal caries (to see depth)
Why should lesions close to the DEJ and in dentine should be monitored at shorter intervals than enamel lesions?
Caries progression is faster in dentine than in enamel.
