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.
Alternative NamesX-ray - teeth; Radiograph - dental; Bitewings; Periapical film; Panoramic film
How the test is performedThe test is performed in the dentist's office. There are four types of x-rays:
The bitewing is when the patient bites on a paper tab and shows the crown portions of the top and bottom teeth together.
The periapical shows one or two complete teeth from crown to root.
A palatal or occlusal x-ray captures all the upper and lower teeth in one shot while the film rests on the biting surface of the teeth.
A panoramic x-ray requires a special machine that rotates around the head. The x-ray captures the entire jaws and teeth in one shot. It is used to plan treatment for dental implants, check for impacted wisdom teeth, and detect jaw problems. A panoramic x-ray is not good for detecting cavities, unless the decay is very advanced and deep.
In addition, many dentists are taking x-rays using digital technology. The image runs through a computer. The amount of radiation transmitted during the procedure is less than traditional methods.
How to prepare for the testThere is no special preparation. Notify the dentist if you are pregnant.
How the test will feelThe x-ray itself causes no discomfort. Some people find that biting on the piece of film makes them gag. Slow, deep breathing through the nose usually relieves this feeling.
Why the test is performedDental x-rays help diagnose disease and injury of the teeth and gums.
Normal ValuesThe x-rays show a normal number, structure, and position of the teeth and jaw bones. There are no cavities or other problems.
What abnormal results meanDental x-rays may be used to identify the following:
There is very low radiation exposure. However, no one should receive more radiation than necessary. A lead apron can be used to cover the body and reduce radiation exposure. Pregnant women should not have x-rays taken unless absolutely necessary.
Special considerationsDental x-rays can reveal dental cavities (tooth decay) before they are visible even to the dentist. Many dentists will take yearly bitewings to catch the early development of cavities.
Another imaging test, called cone beam computerized tomography (CBCT), may be used prior to dental surgery, especially when multiple implants are being placed. This test is usually done in a hospital or imaging center.
Dental xrays are not harmful to you or your baby. So, you do not have to worry about hurting yourself or your baby. They are completely safe and recommended if you need one done.

Pretty sure this is the code for Bitewing xrays that you have taken when you get your teeth cleaned. Dental x-rays of your teeth on both sides. Usually it is 4 x-rays.
Routine checkups and basic cavaity fillings are typically covered by most dental plans. This can vary based on the plan. Most dental plans cover check ups and cleanings. Fillings are usually covered at a reduced rate. Xrays are not always covered. Root canals and crowns are only sometimes covered.
They experimented with xrays on the prisoners in the concentration camps. Mostly at Auschwitz.
I just got my xrays taken for my left knee, it was four xrays for $100, it may be more other places
Yes you can work without being certified, depending on what state you live in. Most dental offices prefer you to be certified because you have to take xrays. The only downsize of your question is it can affect your pay, but if you can get certified do it.
Xrays are damaging to developing babies. Only as last resort.
a person who translates your xrays is called a radiologist.
The amount of xrays produced in a photoelectric effect varies. . . . alot.
No, they did not.
