Answer 21

1. Caries is a BACTERIAL infection caused by acidogenic bacteria in tooth biofilm

Question 22

The FDI supports the principles of _____ _______ dentistry in the management of dental caries.

Answer 22

minimal intervention

Question 23

What are the five FDI basic Cambra Principles?

Answer 23

1. Modification of the oral flora to favor health

5. Repair of defective restorations

Question 24

What is modification of the oral flora?

Answer 24

primary focus should be on control of the infection, plaque control, and reduced carbohydrate intake

Question 25

What is patient education?

Answer 25

the etiology of dental caries should be explained to the patient, together with the means of prevention through dietary and oral hygiene measures

Answer 27

True

Question 28

Question 29

True or False: Removal of restorations results in an inevitable increase in cavity size as a consequence of removal of sound tooth structure.

Answer 29

True

Question 30

_______ of defective restorations should be considered as an alternative to replacement in some circumstances.

Answer 30

Repair
