Which person is associated with designing intra-oral cassettes and promoting radiation protection in 1896?

• A. Gustav Peter Bucky
• B. William H. Rollins
• C. Hollis Elmer Potter
• D. Clarence Dally

Answer: (B)

William H. Rollins was an early champion of safety in dental radiography. In 1896 he publicly warned about the hazards of X-ray exposure and urged protective measures for both patients and practitioners, laying the groundwork for radiation protection practices. He also worked on practical imaging equipment for intraoral use, contributing to the development of film holders or cassettes designed to position the film inside the mouth while controlling exposure. This combination of safety advocacy and early device design is what ties him to both radiation protection and intra-oral imaging. The other figures are known for different innovations or later developments (for example, the grid was introduced later, and Dally is noted for injuries), so Rollins is the best fit for this description.
