Operative II Quiz 2 Que & Answ 2024| A+Answers
1. class III caries: proximal surfaces of anterior teeth
*third most common cavity location!
2. Where is Class III caries usually found relative to the interproximal contact w/
adjacent tooth?: It is found gingival to the contact!
3. Do Class III caries include the incisal edge?: no
4. What are the two broad reasons for restoring Class III?: 1) primary caries (50%)
2) replacement of old restorations (50%) - due to recurrent caries or esthetic reasons
5. What are two reasons that an old restoration would be replaced?: • recurrent caries
(>50%)
•esthetics (discoloration, wear, fractures)
6. Describe the Class III caries progression.: • plaque sticks around contact point
•no flossing • demineralization • cavity extends to DEJ
•surface remineralizes (fluoride) while dentin remains unmineralized
7. How does the tooth surface remineralize?: fluoride from water, toothpaste, or mouth
rinse
8. What are two aspects of the clinical examination for caries?: • visual assess- ment
•tactile assessment
9. While
examining teeth for caries, they must be and
.: clean; dry!!
10.What are three factors that ensure a proper visual assessment?: • good lighting
•dry field! (proper isolation- cotton rolls, gauze)
•magnification

11.During a visual assessment, what are you looking for?: • change in color - often
darker, gray
•change in opacity - more opaque
12.How is transillumination used to visualize caries?: • teeth are translucent
•decalcified enamel, dentin, & tooth-colored restorations absorb light and can be
detected
13.What is the best clinical indicator of carious dentin?: Hardness
14.What technique should and should not be used during a tactile assess- ment?: •
YES - spoon excavator (feel for softness of dentin)
• NO!! - explorer tip (do NOT check for "stick", this aids bacterial progression to pulp)
15.Why should you not used an explorer tip during a tactile assessment?: the tip may
poke the pulp and introduce bacteria
16.A examination should always be an adjunct to
clinical examination.: radiographic
- Radiolucency -> caries!
17.What does "CARS" stand for?: caries associated with restorations or sealants (aka
recurrent or secondary caries)
18.When is composite resin typically used?: when the lesion is surrounded
primarily by enamel, since composite resin binds well to enamel
19.When is resin modified glass ionomer typically used?: • when the lesion is
surrounded by cementum & dentin (when cavity extends gingivally, or onto root surface)
•higher caries risk individuals
20. Which restoration technique is the most common for Class III caries?: -
Class III lingual approach
21.Which restoration technique is the least visible from the facial view?: Class III
lingual approach
