Answer 7

Holding devices

to limit the amount of radiation exposure

proper technique that creates quality image a minimum distance of 6 feet is recommended from the radiation source

an apron with a collar to protect the thyroid gland

and for females ask possibility of pregnancy

mask assistant

lead apron

and gloves

Question 10

Digital radiography

Answer 10

Has been used in dentistry since 1987

Note that digital radiography/ digital images are not radiographs but electronic signals that are captured by sensors displayed on the computer almost instantly

Question 11

Sensor film

Answer 11

The component that receives the radiation source while taking radiography

Question 12

Direct digital imaging (digital sensor)

Answer 12

Charged coupled device (CCD) sensor

Requires less radiation in order to produce a quality image

Question 13

Phosphor storage plate (PSP)

Answer 13

Thin flexible plate

Scanner require to read the info stored on the plate and then convert into a digital image

Question 14

Position instruments are used to

Answer 14

Position and whole dental films or sensors in patients mouth

Keeps patience fingers from being exposed

Assist operator in properly placing the film or sensor



Question 15

Beam alignment device

Answer 15

It is a position instrument

Used to align the beam and assist in positioning of the PID in relation to the tooth in film or sensor

Question 16

What are the usual series of intramural imaging radiographs used in pediatric dentistry

Answer 16

Bitewings (PW)

Periapical (posterior & anterior) (PA)

Occlusal

Question 17

What is the extraoral radius called

Answer 17

A panoramic radiograph these radiographs provide general view of teeth and surrounding structures

Question 18

What do panoramic radiograph capture

Answer 18

They capture the entire mouth in a single image including the teeth upper and lower jaws surrounding structures and tissues

Question 19

BiteWing radiographs are used to

Answer 19

Visualize the crowns of posterior teeth and examine for interdental or recurrent carries

Question 20

Periapical Radiographs are generally used to

Answer 20

Capture the tip of the route on film to determine the cause of pain this allows dentist to visualize the tooth as well as the surrounding bone

Question 21

The occlusal radiographs are used to

Answer 21

Health check the development and placement of a section of entire arts of teeth in the upper or lower jaw they mostly used to buy pediatric dentist to find children’s teeth that have not yet broken through the guns

Question 22

The batwing radiographic image shows

Answer 22

The upper and lower teeth in occlusion

Only crowns in small portions of the root are also seen

And the purpose is to evaluate and detect interproximal carries and evaluate bone levels



Question 23

The periapical image shows

Answer 23

View used to diagnose pathological conditions of the tooth root and bone as well as a mouth formation and irruption

Question 24

Some main clinical indications for periapical radiography include

Answer 24

Detection of ethical infection/inflammation

After trauma to the teeth and associated alveolar bone

Assessment of the presence and position of unerupted teeth

Assessment of root morphology before extractions

Question 25

The sensor of an occlusal Is placed

Answer 25

In the mouth between occlusal surfaces of the maxillary and mandibular teeth

Question 26

Full mouth survey (fmx)

Answer 26

An intraoral full mouth survey (FMX) contains both: periacapal images and bitewing images

Question 27

Falmouth survey consist of 18 to 20

Answer 27

Images for the average adult

However the number may vary depending on the dentists preference

and the number of teeth present usually the anterior region is where the number of images varies

Also the size of the sensor if you are using digital and the technique used

Question 28

Intraoral imaging techniques

Answer 28

Whether using conventional film digital sensors are phosphor storage plates there are two basic techniques for the obtaining periapical images:

Paralleling technique

Bisecting Technique
