Cariology Flashcards
1
Q
What is a white spot lesion
A
Chalky white appearance due to increased porosity due to loss of mineral form the surface of the crystals
Clinically visible after 4 weeks
Hard to probe
2
Q
What happens under the microscope after 1 week of plaque presence
A
Increased surface porosity
Dissolution of perikymata
Enlarged intercrystalline spaces/pores
3
Q
What are liquefaction foci
A
Coalescing and broken down dentinal tubules
They fill necrotic debris
Increase in size by expanding causing adjacent tubules to distort
4
Q
What are dead tracks
A
Within the sclerotic zone
Form due to the dying back of the odontoblastic processes into their cell bodies
