Iowa Dental Assistant Registration: Radiology Questions and Answers Already Passed

Iowa Dental Assistant Registration: Radiology Questions and Answers Already Passed What two agencies oversee dental radiography? What is the function of each with respect to dental radiography? 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? 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? Dentist must order the films. Dentist must provide personal supervision of trainee What three things are required to obtain radiography qualification from the Board? Course of study that includes clinical training, examination, and an application with fee When is the radiography qualification renewed? What are the renewal requirements? Renewed when registration is renewed - by August 31 of odd-numbered years What are the renewal requirements for dental radiography? Renewal requires proof of 2 hours of continuing education in dental radiography and renewal fee Name two possible penalties for violating dental radiography requirements. Disciplinary action by the dental board Criminal charges or civil action T/F: A dentist should always prescribe radiographs every six months to review a patient's dental condition. False T/F: A certified dental assistant does not need to obtain a separate radiography qualification from the Board to take x-rays. False T/F: Dental assistant trainees can train in dental radiography during the trainee period. True T/F: The Iowa Dental Board inspects dental radiography machines. False What are the parts of the control panel? What is the function of each part? 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? Motion to the electrons Something to stop the electrons What determines the number of electrons that will be used? mA and time What role does kinetic energy play in the creation of x-rays? 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 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? 80 kVp What is the function of the PID? Aim the central rays - used to aim the x-rays If the patient moves during the exposure, which film quality is affected? Detail, aka definition What should you do to lighten a film's density? Decrease
