Radiology Exam for Dental Assistant Questions and Answers 2024 Dental Radiography - ✔✔The act of creating permanent visual image (representing different densities) by using penetrating radiation through the object. A diagnostic method necessary to scree n for and identify possible oral conditions - * Non -invasive means * Very little risk for patient if done correctly Importance of Dental Radiography - ✔✔Enables dental professionsal to identify many conditions that may otherwise go undetected. Non-invasiv e techniques Low risk for patient if done correctly Diagnostically pricess - *detection of dental disease *Trauma evaluation *Growth and Development *Oral pathology Patient educational tools Wilhelmina Conrad Roentgen (1895) - ✔✔Discovered x -radiation: the penetrating radiation that produces the pictures on the film. *"X" represents the unknow because he could not explain the glow he discovered. Proved that x -rays penetrated paper and wood, but not metals. X-rayed his wife's hand during many experiments Dr. Otto Walkoff (1895) - ✔✔First to apply x -radiation to the oral cavity (on cadavers) and expose dental radiograph Did so only 2 weeks after the discovery of x -rays His film took 25 minutes to expose *Tod ay we can expose 1/10th of a second Dr. C Edmond Kells (1896) - ✔✔Exposed first dental radiograph in the US on a living person Insisted that dentists incorporate radiography into treatment planning and diagnosis. Discovered how to adjust the strength of X-rays. Took many radiographs of his own hands *During the taking of oral films via holding it in his own mouth or others Fingers amputated due to excessive radiation exposure Eventuallly committed suicide William David Coolidge (1913) - ✔✔Introduced th e hot cathode ray tube Was working for General Electric at the time Has his PhD in electrical engineering, he was not a dentist Contributed once again to developing a safe housing for the x -ray machine ALARA - ✔✔As Low As Reasonably Achievable All exposure to radiation must be kept to a minimum Every possible method of reducing exposure to radiation should be employed to minimize risk Background radiation - ✔✔Dental x -rays are artificially produced so they are NOT background radiation Definiti on - ionizing radiation that is always present in our environment ***cosmic radiation (outer space), terrestrial radiation (earth and its environment), internal (from our own body) Average level of US is 3mSv per year Makes up 83% of our radiation exposu re per year In-otero Effects - ✔✔10-25 rads would be necessary to cause birth defects to the fetus Only 0.00003 rads exposure in a full set of radiographs even without the lead apron Impossible for dental x -ray exposures to cause birth defects Collimatio n - ✔✔A circular collimating required by federal regulations to restrict the beam to no more than 2.75 inches as it exists from the cone and reaches the skin of the patient. A rectangular collimating is better because it reduces radiation exposure to the patient by up to 70% ***More technique sensitive, especially if not using film holding/beam aiming devices Types of Energy - ✔✔Energy travels in waves ***Even baseballs travel in waves, just not distinguishable visually Electromagnetic: wavelike energy th rough space or matter ***Cosmic.
