Iowa Dental Board Radiography
What two agencies oversee dental radiography? What is the function of each
with respect to dental radiography? - correct answer ✔Iowa Department of
Public Health: state radiation control agency, inspects facilities;
Iowa Dental Board: ensures that dental assistants meet minimum training
standards; issues qualification in dental radiography
Under what conditions can a dental assistant take radiographs? - correct
answer ✔Assistant must have added qualified in dental radiography or be on
trainee status
Dentist must order the films
Dentist must provide supervision
Under what conditions can a dental assistant trainee take radiographs? -
correct answer ✔Dentist must order films
Dentist must provide personal supervision of trainee
What three things are required to obtain radiography qualification from the
Board? - correct answer ✔Course of study that includes clinical training,
examination, and an application with fee
When is the radiography qualification renewed? What are the renewal
requirements? - correct answer ✔Renewed with registration is renewed - by
August 31 of odd-numbered years
What are the renewal requirements for dental radiography? - correct answer
✔Renewal requires proof of 2 hours of continuing education in dental
radiography and renewal fee
,Name two possible penalties for violating dental radiography requirements. -
correct answer ✔Disciplinary action by the dental board
Criminal charges or civil action
A dentist should always prescribe radiographs every six months to review a
patient's dental condition. - correct answer ✔False
A certified dental assistant does not need to obtain a separate radiography
qualification from the Board to take x-rays. - correct answer ✔False
Dental assistant trainees can train in dental radiography during the trainee
period. - correct answer ✔True
The Iowa Dental Board inspects dental radiography machines. - correct
answer ✔False
What are the parts of the control panel? What is the function of each part? -
correct answer ✔Timer: controls how long electrons move-length of
exposure
mA setting: determines the number of electrons available
kVp setting: determines the force of electron movement
A source of electrons is needed to create x-rays. What else is needed to
create x-rays? - correct answer ✔Motion to the electrons
Something to stop the electrons
What determines the number of electrons that will be used? - correct answer
✔mA and time
, What role does kinetic energy play in the creation of x-rays? - correct answer
✔Electrons in motion possess kinetic energy; Kinetic energy from electrons in
motion is converted into heat and x-rays when the electrons are stopped
What does the force of electron movement have to do with the x-rays that are
created? - correct answer ✔Force of movement determines force of x-ray
The greater the movement force, the more powerful the x-rays
Which x-ray has more penetrating power, one that was created with a kVp of
60 or an x-ray that was created with a kVp of 80? - correct answer ✔80 kVp
What is the function of the PID? - correct answer ✔Aim the central rays -
used to aim the x-rays
If the patient moves during the exposure, which film quality is affected? -
correct answer ✔Detail, aka definition
What should you do to lighten the film's density? - correct answer
✔Decrease the mA or decrease time
If the dentist looks at some films and tells you she wants more shades on the
next film, what would you adjust? - correct answer ✔Increase the kVp to
increase the number of shades (high kVp yields long scale contrast)
Name four factors of a diagnostically acceptable radiograph. - correct answer
✔Proper density, contrast and detail; shows entire area and surrounding
structures
Where would you look to find the collimator? - correct answer ✔Base of the
PID
