Lecture 2

Question 1

class I classification

Answer 1

caries within the pits and fissures of all teeth

Question 2

incipient caries

Answer 2

reversible - just started - can remineralize - hasn’t passed the DEJ

Question 3

Small caries

Answer 3

just crossed DEJ

Question 4

Moderate Caries

Answer 4

crossed & spread into DEJ

Question 5

Extensive Caries

Answer 5

closing in on pulp - reparative Dentin forms from pulp

Question 6

Caries are classified by

Answer 6

pit & fissure caries & smooth surface caries

Question 7

active caries

Answer 7

rampant - rapidly invading softer lesions

chronic - slow, long standing, dark in color and so there is a good chance of remineralization

Question 8

arrested caries

Answer 8

not showing any further progress

Question 9

recurrent/secondary caries

Answer 9

caries under a pre-existing faulty restoration

Question 18

axial walls

Answer 18
