Digital X-rays
Three basic kinds of X-Rays are;
1. The most common kind of x-rays are bitewings, which help detect spot cavities and decay.
2. Deep Tooth problems such as impacted teeth, bone loss and abscesses are detected using periapical x-rays, which give broad pictures of the entire tooth structure.
3. Panoramic x-rays are designed to capture an entire mouth, and have been used to spot tumours and cysts, as well as wisdom teeth.
There is no reason to be concerned about radiation. You are exposed to more radiation from the sun in one day, than one sitting of x-rays.
Exposure of radiation is very slight and brief, safety precautions such as high speed film, minimize exposure time, and lead aprons prevent exposure to surroundings areas of the body such as the head, neck and upper chest.
