Key Discoveries and Innovations
- X-ray Discovery: Discovered by physicist Wilhelm Conrad Roentgen.
- Roentgen's Naming: Named his discovery "X-rays," denoting the unknown.
- First Dental Radiograph in the U.S.: Made using a living person by Dr. William H. Rollins.
Radiographic Techniques
- Extraoral Imaging Technique: Panoramic radiography views the entire dentition in a single image.
- Extraoral X-ray Machine Components: Includes a tube head, receptor, and collimating device.
- Collimating Device Function: Restricts the size of the x-ray beam to minimize exposure.
- Beam Alignment Device Purpose: Ensures the x-ray beam is directed correctly at the receptor holder.
Imaging Components
- Receptor Holder Purpose: Holds the receptor in place during exposure to dental radiographs.
- Beam of Energy: X-ray beams penetrate substances and create image shadows on receptors.
- Recording Medium in Dental Imaging: Referred to as dental film or digital receptors.
Additional Notable Contributions
- First Practical Use of Radiographs in Dentistry: Credited to Dr. Otto Walkhoff, who created images in 1896.
- Foil and Cathode Ray Discovery: Achieved by Wilhelm Röntgen, who showed that cathode rays could penetrate aluminum foil, causing fluorescence.
