1. Radiation is defined as a. a form of energy carried by waves or streams of particles. b. a beam of energy that has the power to penetrate substances and record image shadows on a receptor. c. a high-energy radiation produced by the collision of a beam of electrons with a metal target in an x-ray tube. d. a branch of medicine that deals with the use of x-rays. ANS: a Radiation is a form of energy carried by waves or streams of particles. An x-ray is a beam of energy that has the power to penetrate substances and record image shadows on a receptor. X-radiation is a high-energy radiation produced by the collision of a beam of electrons with a metal target in an x-ray tube. Radiology is a branch of medicine that deals with the use of x-rays. 2.

Your patient asked you why dental images are important. Which of the following is the correct response? ANS: d a. An oral examination with dental images limits the practitioner to what is seen clinically. b. All dental diseases and conditions produce clinical signs and symptoms. c. Dental images are not a necessary component of comprehensive patient care. d. Many dental diseases are typically discovered only through the use of dental images. An oral examination without dental images limits the practitioner to what is seen clinically. Many dental diseases and conditions produce no clinical signs and symptoms. Dental images are a necessary component of comprehensive patient care. Many dental diseases are typically discovered only through the use of dental images.

The x-ray was discovered by a. Heinrich Geissler. b. Wilhelm Roentgen. c. Johann Hittorf. d. William Crookes. ANS: b Heinrich Geissler built the first vacuum tube in 1838. Wilhelm Roentgen discovered the x-ray on November 8, 1895. Johann Hittorf observed in 1870 that discharges emitted from the negative electrode of a vacuum tube traveled in straight lines, produced heat, and resulted in a greenish fluorescence. William Crookes discovered in the late 1870s that cathode rays were streams of charged particles. PTS: 1 DIF: Recall REF: Page 1 | Page 2 OBJ: 4 TOP: CDA, RHS, III.B.2.

Who exposed the first dental radiograph in the United States using a live person? Otto Walkoff was a German dentist who made the first dental radiograph. Wilhelm Roentgen was a Bavarian physicist who discovered the x-ray. Edmund Kells exposed the first dental radiograph in the United States using a live person. Price introduced the bisecting technique in 1904.

Current fast radiographic film requires the initial exposure times used in 1920. a. 33 b. 98 c. 73 d. 2 ANS: b % less exposure time than Current radiographic film requires more than 33% less exposure time than times in 1920. Current fast radiographic film requires 98% less exposure time than the initial exposure times used in 1920, which, in turn, reduces the patient's exposure to radiation. Current radiographic film has reduced exposure time more than 73%. Current radiographic film requires less than 2% of the initial exposure times needed in 1920.
