Q: When primary teeth are being exfoliated and permanent teeth move in to take their places, which occurs between the ages of 6 and 12 years, this is considered:
- mixed dentition
- secondary dentition
- tertiary dentition
- primary dentition
A: mixed dentition

Q: What organization defines dental caries as a "localized, posteruptive, pathologic process of external origin involving softening of the hard tooth tissue and proceeding to the formation of a cavity"?
- American Dental Association
- World Health Organization
- Centers for Disease Control
- International Association of Dental Research
A: World Health Organization

Q: All of the following are requirements for the development of a carious lesion except:
- microorganisms
- carbohydrates
- biofilm
- susceptible tooth surface
A: biofilm

Q: An example of a compound cavity is:
- occlusal
- mesial-occlusal
- facial
- mesial-occlusal-distal
A: mesial-occlusal

Q: Incipient lesions involve subsurface demineralization, which appears as a white area with no breakthrough to the enamel surface. Untreated incipient lesions are not visible by observation and are regular to gentle application of the side of an explorer tip or blunt probe.

A: The first statement is true and the second statement is false

Q: What are the two types of dental caries described by location?
- Attrition and erosion
- Panoramic and extraoral
- Pit and fissure, and smooth surface
- Translucent and opaque
A: Pit and fissure, and smooth surface

Q: A form of caries found in young children is known as:
- smooth surface
- early childhood
- incipient
- pit and fissure
A: early childhood

Q: All of the following are predisposing factors for early childhood caries except:
- prolonged at-will breastfeeding
- pacifier dipped in or filled with a sweet agent, such as honey
- nursing bottle that contains sweetened milk or other fluid sweetened with sucrose
- nursing bottle filled with water
A: nursing bottle filled with water

Q: A soft, progressive lesion of cementum and dentin that involves bacterial infection and invasion is known as:
- root caries
- incipient lesion
- pit and fissure caries
- smooth surface caries
A: root caries

Q: The critical pH for cementum is:
- 4.5 to 5.0
- 6.0 to 6.7
- 7.0 to 7.7
- 8.0 to 8.7
A: 6.0 to 6.7

Q: A defect that occurs as a result of a disturbance in the formation of the organic enamel matrix is known as:
- enamel hypoplasia
- attrition
- erosion
- abrasion
A: enamel hypoplasia

Q: The wearing away of a tooth as a result of tooth-to-tooth contact is known as:
- erosion
- attrition
- abrasion
- enamel hyperplasia
A: attrition

Q: The loss of tooth substance by a chemical process that does not involve known bacterial action is known as:
- erosion
- attrition
- bruxism
- enamel hyperplasia
A: erosion

Q: Trauma to the face may involve fractured bones and teeth in addition to soft tissue injuries. The line of fracture may be horizontal, diagonal, or vertical.

Q: Dry each tooth or group of teeth with compressed air for aiding in the recognition of carious lesions. When conducting a visual examination, only look for translucency and no color changes.

Q: All of the following are variations in color and translucency except:
- chalky white
- grayish-white discoloration
- grayish-white color spreading
- grayish-orange
A: grayish-orange

Q: All of the following are factors that influence a patient's response to a pulp test except:
- degree of pulpal degeneration or inflammation
- pain threshold
- reaction to pain
- opposite metal restorations
A: opposite metal restorations

Q: Cold testing may be accomplished with an air blast, cold drink, ice stick, ethyl chloride in a spray or on a cotton swab, or a carbon dioxide dry-ice stick. Heat testing is accomplished by warming a temporary stopping (gutta-percha) and applying it to a tooth dried with a cotton sponge.

A: The first statement is true and the second statement is true

Q: False-negative responses to electrical pulp testing can occur because of all of the following except:
- premedication with analgesics
- recently traumatized tooth
- pulp canal wide
- immature tooth
A: pulp canal wide

Q: A root surface lesion starts near the:
- cementoenamel junction after gingival recession has exposed the root surface
- dentinoenamel junction after gingival recession has exposed the root surface
- enamocementum junction after gingival recession has exposed the root surface
- cementodentin junction after gingival recession has exposed the root surface
A: cementoenamel junction after gingival recession has exposed the root surface
