Radiology 2

Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. According to the principles of shadow casting - preferred object-film distance






2. What is the purpose of replenishing the developer solution






3. Mand premolar anatomy






4. When looking at radiographs that were taken several years ago - you notice a brownish stain which makes interpretation difficult. What caused this?






5. According to principles of shadow casting - How should the film be placed in relation to the tooth?






6. When taking a radiograph - you pull the end of the PID away from the patients face about 6 inches. How will this affect the radiographic image and patient exposure






7. What is the purpose of taking radiographs of an edentulous patient






8. What types of cells must be effected in order for mutation to occur






9. What exposure is taken to determine jaw relationships in ortho treatment planning






10. How does resolutiong and detial of a panoramic radiograph compare with that of PA's and BW's






11. What is the optimum processing temp.






12. What are the long term effects of radiation exposure






13. What exposure would be useful in identifying salivary stones in the submandibular gland






14. What controls the speed with which the electrons travel from the cathode to the anode






15. What are the short term effects of radiation exposure






16. How should x-ray film be stored






17. What type PID significantly reduces exposure to the patient






18. Size film used for anterior PA's for patients with narrow arches






19. You process a set of BW's in the automatic processor. three of the BW's are of good quality - but fourth is completely blank. What probably caused this?






20. What is the purpose of the lead foil?






21. when manually processing dental film - you notice the temp. has gotten warmer as the day progressed. How should the developing time be changed?






22. What 2 unites are used to measure biologic effect and dose equivalent
