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 im ageshadows on a receptor. c. a high- energy radiation produced by the collision of a beam of electrons with amet al target in an x-ray tube. d. a branch of medicine that deals with the use of x-rays. ANSWER:C A Radiation is a form of energy carried by waves or streams of particles. An x- ray is a beam ofenergy that has the power to penetrate substances and record image shad ows on a receptor. X-radiation is a high- energy radiation produced by the collision of a beam of electrons with ametal target in an x-ray tube. Radiology is a branch of medicine that deals with the use of x-rays.

A radiograph is defined as a. a beam of energy that has the power to penetrate substances and record im ageshadows on a receptor. b. a picture on film produced by the passage of x-rays through an object or body. c. the art and science of making radiographs by the exposure of an image recepto r tox-rays. d. a form of energy carried by waves or a stream of particles. ANSWER:C B An x- ray is a beam of energy that has the power to penetrate substances and record image shad ows on a receptor. A radiograph is a picture on film produced by the passage of x- rays through an object or body. Radiography is the art and science of making dental imag es by theexposure of a receptor to x- rays.

YourCpatient asked you why dental images are important. Which of the following is thecorrect response? a. An oral examination with dental images limits the practitioner to what is se en 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 den talimages. ANSWER:C D 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 typicall y 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 ANSWER:C 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 t he negative electrode of a vacuum tube traveled in straight lines, produced heat, and result ed in a greenish fluorescence. William Crookes discovered in the late 1870s that cathode r ays were streams of charged particles. DIF: Recall REF: Page 2 OBJ: 4 TOP: CDA, RHS, III.B.2.

Who exposed the first dental radiograph in the United States using a live person? a. Otto Walkoff b. Wilhelm Roentgen c. Edmund Kells d. Weston Price ANSWER:C C Otto Walkoff was a German dentist who made the first dental radiograph. Wilhelm Roentg en was a Bavarian physicist who discovered the x- ray. Edmund Kells exposed the first dental radiograph in the United States using a live pers on. Price introduced the bisecting technique in 1904. DIF: Recall REF: Page 4 OBJ: 5 TOP: CDA, RHS, III.B.2.

Who modified the paralleling technique with the introduction of the long-cone technique? a. C. Edmund Kells b. Franklin W. McCormack c. F. Gordon Fitzgerald d. Howard Riley Raper ANSWER:C C C. Edmund Kells introduced the paralleling technique in 1896. Franklin W. McCormack r eintroduced the paralleling technique in 1920. F. Gordon Fitzgerald modified the parallelin gtechnique with the introduction of the long- cone technique. This is the technique currently used.

Increased patient radiation exposure b. Increased patient comfort c. Increased speed for viewing images d. Increased chemical usage ANSWER:C C Patient exposure is reduced with digital imaging. Digital sensors are more sensitive to x- rays than film. Digital sensors are rigid and bulky, causing decreased patient comfort. The i mage from digital sensors is uploaded directly to the computer and monitor without the nee d for chemical processing. This allows for immediate interpretation and evaluation.

Beta particles b. Alpha particles c. Cathode rays d. Radioactive materials ANSWER:C C Beta particles are fast moving electrons emitted from the nucleus of radioactive atoms and arenot associated with x- rays. Alpha particles are emitted from the nuclei of heavy metals and arenot associated wit h x-rays. Wilhelm Roentgen was experimenting with cathode rays when he discovered x- rays. Radioactive materials are certain unstable atoms or elements that are in the process of spontaneous disintegration or decay. DIF: Comprehension REF: Page 3 OBJ: 4 TOP: CDA, RHS, III.B.2.

Which of the following would you place in the patient’s mouth in order to take dental x- rays? a. Image b. Image receptor c. Radiograph d. Dental radiograph ANSWER:C B An image is a picture or likeness of an object. An image receptor is the recording mediu m (film, phosphor plate, or digital sensor) that is placed in the patient’s mouth to record t he image produced by the x-rays. A radiograph is an image of two- dimensional representationof a three- dimensional object. A dental radiograph is the dental ima
