Among the most significant, yet totally invisible parts, of the electromagnetic spectrum are X-rays. Their most unique attribute is their capability of entering solid objects. They are then either absorbed or pass on through the object. If the object is very dense, it absorbs more X-rays than an object that is not so dense.
Because teeth and bone are so dense, they absorb most of the X-rays that strike them. Gums and cheeks, on the other hand, let most of the X-rays to pass through them.
When a dentist takes a set of dental X-rays, the patient's cheeks and gums always look darker and tend to lack detail. Teeth show up looking much lighter. Fillings are even denser than bone, so they show up in X-rays as bright areas. Cavities, however, appear as dark patches on the teeth.
There are two types of X-rays. There are those taken with film, and there are those that are taken with Digital Radiographs. Both behave in the same manner, but the digital electronic sensor instantly interprets the data and transmits it to a computer, which then creates an image on the screen.
Invariably, there are always some patients who become nervous when they start to think about exposure to any amount of radiation. It should be pointed out that the X-ray machines used by dentists emit only a tiny amount of radiation.
One or two exposures are not going to harm anyone. However, the effects of cumulative doses can add up over time and have a negative impact on cell growth and vitality. This is why dentists use X-rays on a very judicious basis.
Dentists also take several precautions to further protect the patient from needless radiation exposure.
-The width of the X-Ray beam is limited to an area that is normally less than 3 inches in diameter.
-Routine checks and licensing of all machines ensure that they are operating correctly.
-There are dentists that still drape lead aprons over their patients to provide them with an added precaution and peace of mind. These aprons are not really necessary, but they certainly do not hurt and often help put the patient at ease.
