Question 2

Detects proximal caries on posterior teeth

Answer 2

Horizontal Bitewings

Question 3

Measures bone level in periodontal patients

Answer 3

Vertical Bitewings

Question 4

Records crowns, roots, and supporting structures of individual teeth, usually to detect abnormalities

Answer 4

Periapical Radiographs

Question 5

Records large areas of the maxilla, mandible, or floor of the mouth and detects gross pathological conditions or fractures

Answer 5

Occlusal Radiographs

Question 6

Records the complete maxilla and mandible and is used for screening or evaluation of oral pathology/injuries

Answer 6

Panoramic Radiograph

Question 7

Computer/Database the Navy uses to allow images to appear on a screen within seconds of exposure and can be stored or transferred for diagnosis anywhere within the Regional Dental Facilities

Answer 7

X-Ray Vision

Question 8

Cost of Intra-oral digital sensors

Answer 8

Over $7,000

Question 9

Consists of tungsten filament, when heated, produce electrons to generate the x-ray

Answer 9

Cathode

Question 10

Removes heat from the tungsten target, electrons are directed, reducing the wear on the target

Answer 10

Anode

Question 11

Cathodes produce what type of charge

Answer 11

Negative

Question 12

Anodes produce what type of charge

Answer 12

Positive

Question 13

Control Devices:

Three settings that are critical to producing diagnostic quality radiographs

Answer 13

1. Milliamperage (mA)
2. Kilo Voltage Peak (kVp)
3. Exposure Time

Question 14

The amount of electricity that is applied to the tungsten filament. This produces electrons, and along with the exposure time, this controls the quantity of radiation produced

Answer 14

Milliamperage (mA)

Question 15

This controls the quality of the penetrating power of the x-ray beam

Answer 15

Kilo Voltage Peak (kVp)

Question 16

What is the normal range for the Kilo Voltage Peak setting?

Answer 16

70-90 kVp

Question 17

This determines the amount of time the equipment is activated during exposure of the radiograph

Answer 17

Exposure Time

Question 18

Commonly found Panoramic unit found within the fleet

Answer 18

Planmeca ProMax X-Ray Unit

Question 19

How many presets are found on the Planmeca ProMax X-Ray Unit?

Answer 19

5

Question 20

What are the five presets found on the Planmeca ProMax X-Ray Unit?

Answer 20

1. Child 6 years and under
2. Child 7-12 years
3. Adult female or small male
4. Adult male
5. Large adult male (McPherson)

Question 21

This is the main x-ray system; made of glass; allows electrodes to flow along with the cathode and anode

Answer 21

X-Ray Tubehead

Question 22

TRUE OR FALSE:

Do not allow the patient to bite on the cord of a Intra-Oral Digital Sensor

Answer 22

True

Question 23

Intra-Oral Digital Sensors are available in what sizes?

Answer 23
