The Discovery of the X-Ray : Wilhelm Rontgen discovered that when a very specific type of crystal was placed near a tube in his lab, a vibrant glow was produced.
Dr. Otto Walkhoff – German Physicist who took early dental xrays
The First Dental X-Rays : C. Edmund Kells took the first dental x-ray in his New Orleans dental office.
The Rapid Evolution of the Dental X-Ray : . Some of those changes included using faster film, discovering how to capture images with more detail, and improving the entire process so patients were more comfortable.

It is surprising to many people to discover that it wasn’t until the late 1950s that x-rays were starting to be used regularly in dentist offices
. How Do Today’s Dental X-Rays Help Dentists?
Today’s digital dental x-rays help dentists by providing them with detailed images that can be used to diagnose everything from cavities and infections to tumors and gum disease. These x-rays can be used to spot many dental problems before they become extremely problematic.
Dental x-rays can also be used by dentists to monitor the growth or movement of teeth, determine the extent of damage after an injury or accident, and notice any changes that may have occurred to the structure or shape of the mouth, jaw, or teeth.
The Evolution of Dental X-Rays
A panoramic radiograph is a panoramic scanning dental X-ray of the upper and lower jaw. It shows a two-dimensional view of a half-circle from ear to ear. Wikipedia
Historical milestones for digital panoramic systems
1985–1991 – The first attempt to build a dental digital panoramic was of McDavid et al. at UTHSCSA.[5] Their idea was based on a linear pixel array(single pixel column)sensor which was not appropriate for such an application because: a) there is no tomographic effect; b) huge difficulties to collimate the X-rays beam and to control the X-ray dose delivered to the patient; c) poor generator efficiency.
DXIS – real time display
1995 – DXIS, the first dental digital panoramic X-rays system available on the market, created by Catalin Stoichita at Signet (France). DXIS targeted to retrofit all the panoramic models.
1997 – SIDEXIS, of Siemens (currently Sirona Dental Systems, Germany) offered a digital option for Ortophos Plus panoramic unit, DigiPan of Trophy Radiology (France) offered a digital option for the OP100 panoramic made by Instrumentarium (Finland).
1998–2004 – many panoramic manufacturers offered their own digital systems.
