Caption

Dental radiography (1915). Historical photograph showing the method of taking a dental X-ray from a male patient in 1915. The upper right row of teeth is being X-rayed. The seated patient holds a small photographic film against the back of his upper teeth and roof of his mouth. At the time, the examination of teeth and the jawbone was described as "one of the most important applications of the X-ray". By 1915-1920, the effects of exposure to X-rays were known, and the apparatus had a nozzle which focused the beam. The apparatus was also encased to prevent stray X-rays reaching the patient. X-ray exposure charts and recommended X-ray focal distances were also used.
