Diagrammatic representation of the buccal object rule being employed. In the first radiograph ( left ), the objects appear on the film in almost the same relationship that they share in reality. But by shifting the x-ray collimator (radiation source) to one side and tilting it towards the objects ( right ), the objects appear on the film in a ...
Dental radiographs, commonly known as X-rays, are radiographs used to diagnose hidden dental structures, malignant or benign masses, bone loss, and cavities.. A radiographic image is formed by a controlled burst of X-ray radiation which penetrates oral structures at different levels, depending on varying anatomical densities, before striking the film or sensor.

[4] Richards held six patents for his inventions and was the author of around 100 journal ...
