comprehensive: complementary medicine is another expression for "alternative" medicine, though the two are often linked as complementary and alternative medicine and referred to as CAM. The term 'complementary' seems to have been introduced by the purveyors of quackery in an attempt to produce the bias that untested or discredited treatments should be used along with conventional medical treatments. There really is no such thing as "alternative" medicine; if it's medicine, it's medicine. 'Alternative medicine' is a deceptive term that tries to create the illusion that a discredited or untested treatment is truly an alternative to an established treatment in conventional medicine. By adding 'complementary medicine' to the repertoire of misleading terms, the purveyors of quackery have improved on the illusion that their remedies somehow enhance or improve the effects of standard conventional treatments.
Dental X-rays
Dental X-rays are a type of picture of the teeth and mouth. X-rays are a form of electromagnetic radiation, just like visible light. They are of higher energy, however, and can penetrate the body to form an image on film.
Structures that are dense (such as silver fillings or metal restoration) will block most of the photons and will appear white on developed film. Structures containing air will be black on film, and teeth, tissue, and fluid will appear as shades of gray.
The test is performed in the dentist's office. The most common procedure is a bite-wing, where a small piece of film is placed in the mouth behind a section of the teeth. You are asked to bite down on the paper tab around the film, which holds the film in place.
The X-ray machine is aimed at that section of teeth, and a picture is taken. Most dental X-rays include four or more views of the teeth.
