Study Notes
Discovery of X-rays
- Wilhelm Conrad Roentgen, a professor, discovered x-rays.
- He experimented in Bavaria, Germany on November 8, 1895.
- Roentgen's experiment involved a vacuum tube called Crooke's tube.
- A fluorescent screen near the tube glowed when the tube was activated by an electric current.
- Roentgen was uncertain about the nature of the invisible ray, referring to it as X-ray, where "x" represents unknown.
- Fellow scientists named the invisible ray the Roentgen Ray.
- Images produced on photosensitive film were called a Roentgenograph.
- Due to the similarities between photographic negatives and x-ray film, and the resemblance of x-rays to radio waves, the term radiograph was created by combining the prefix "radio" and the suffix "graph".
Important Scientists and Researchers
- Dr. Friedrich Otto Walkhoff: The first to expose a prototype of a dental radiograph.
- He used a small, glass photographic plate covered with black paper and wrapped in thin rubber.
- He held the film in his mouth for 25 minutes.
- Dr. William H. Rollins: Considered "dentistry's forgotten man" and the father of radiation protection.
- Rollins suffered severe burns to his hand while working with x-rays in 1898.
- He was the first advocate for the science of radiation protection.
- Dr. William J. Morton: Among the first to take radiographs of skulls.
- He discovered impacted teeth radiographically.
- Dr. Charles Edmund Kells Jr.: The first to put the radiograph to practical use in dentistry.
- Dr. William D. Coolidge: An American physicist and engineer who worked for General Electric Company.
- Coolidge introduced the hot cathode tube, also known as the Coolidge tube.
- Dr. Howard R. Raper: The first dental educator to hold the title of "Professor of Radiology".
- He wrote the first dental radiology textbook, "Elementary and Dental Radiology".
- Raper introduced bitewing radiographs in 1925.
- Gordon Fitzgerald: Introduced the long cone paralleling technique in 1947.
- Franklin McCormack: First to use the paralleling technique in intraoral dental radiography.
- Weston Price: Developed the Bisecting Angle technique in 1904.
