Cavity Classification According To The Proximity To The Pulp

Question 1

The classification of the cavity according to their proximity to towards the pulp?

Answer 1

-shallow cavity
-moderately deep cavity
-deep cavity
-deep cavity with exposure of the pulp

Question 2

Steps in shallow cavity preparation in Amalgam?

Answer 2

-no need for base material
-using 2 thin coats of varnish or amalgam bond

Question 3

Steps in shallow cavity preparation in composite restoration?

Answer 3

-cavity is etched
-coating with bonding agent

Question 4

Steps in moderately deep cavity restoration?

Answer 4

-varnish is used to coat floor and walls
-cement base is placed such as zinc phosphate or modified zinc oxide eugenol

Question 5

Steps in deep cavity preparation?

Answer 5

-put calcium hydroxide on the pulpal and axial walls
-cement base is places such as zinc phosphate,modified zinc oxide eugenol and polycarboxylate
-varnish is used to coat the walls

Question 6

Explain the new protocol in deep cavity?

Answer 6

-using dycal and glass ionomer cement base

Question 7

Why it is preferred to use dycal with glass ionomer cement base?

Answer 7

Because of the chemical bonding between the glass ionomer and the tooth,that will reduce:
-microleakage
-post operative sensitivity

Question 8

Steps in deep cavity with exposed pulp preparation?

Answer 8

-putting carefully the calcium hydroxide on the pulp
-choosing base material such as(zinc phosphate,reinforced ZOE)

Question 9

Tertiary dentin formation is induced by which material?how long it takes?

Answer 9

Calcium hydroxide,it takes 2 weeks

Question 10

Which one of cement base is preferred in exposed pulp-deep cavity?

Answer 10

Glass ionomer cement
