Par 2 - TR

Question 1

T/F? Elastic modulus of a composite does not depend on resin content.

Answer 1

TRUE. It depends on filler content.

Question 2

Volumetric contraction of composite resin occurs following light polymerization, this causes a  ____% decrease in volume of the composite

Answer 2

1.5%-5%

Question 3

Potential solutions to improve proximal contact placement and position include which of the following choices?

Answer 3

use a tension ring sectional system

Question 4

Which of the following matrix systems did we use in lab to achieve tight contact in the insertion of quadrant Class II resins?

Answer 4

triodent V3 ring and sectional matrix system

*our class may have had palodent instead…

Question 5

Complex intracoronal restorations can be utilized for all the following situations except

Answer 5

indirect restoration when significant occlusal problems exist

Question 6

T/F? Static tooth contacts include centric contact and maximum intercuspation. Dynamic tooth contacts include protrusive and lateral excursions.

Answer 6

TRUE, TRUE.

Question 7

Assuming patient had normal teeth in class 1 occlusion, tooth 30 would ideally have how many contact points?

Answer 7

15

Question 8

Which of the following would be the correct sequence of treatment?

Answer 8

Outline form, convenience form, carious removal, refinement of
walls

Question 9

T/F? Resistance form is more easily achieved for complex inner!coronal restorations than for indirect extra coronal restorations.

Answer 9

FALSE. To make it true, it should say RETENTION form.

Answer 10

parallel facial and lingual walls, occlusal accessory grooves, friction of proximal walls

Question 11

What are the examples of secondary forms or features of retention?

Answer 11

slots, locks, coves
