Back 18

Electronic Sensors are used in lieu of standard x-ray films when recording images of a patient's teeth. While standard films can have their image scanned into an electronic program, they are not by definition, digital x-rays.

Front 19

Which of the following inflicts the most radiation on a patient?

FMX

Panoramic

Bitewing series

PA

Back 19

FMX series inflicts more radiation on a patient because they require multiple exposures for all 20 films. There is less radiation needed with a panoramic x-ray.

Front 20

What step helps prevent a large radiolucent area near the palate as seen on panoramic x-rays?

Back 20

Having a patient place their tongue on the roof of their mouths during a panoramic x-ray prevents a large radiolucent area in the palate on the processed x-ray.

Front 21

Why does digital radiography require less radiation than traditional x-rays?

Back 21

It uses lower wave-length radiation.

Sensors are more sensitive with digital radiography than traditional x-ray films, allowing the exposure time to be less, reducing radiation.

Front 22

Digital x-ray sensors:

Cannot be sterilized

Are sealed and waterproof

Must be covered by a barrier

All Of The Above

Back 22

Intraoral senors are waterproofed by the manufacturer, but because they cannot be sterilized, they must have a disposable barrier placed on them prior to use with each patient.
