Dental x-rays are an important part of your regular dental visits to aid in diagnosing problems that are not visible to the naked eye. Digital x-rays are a form of imaging using sensors versus traditional film. A digital x-ray allows the dentist or hygienist to take an image of a tooth or teeth and place it into an imaging program. This gives an immediate image preview onto the computer screen. With this image, the dentist is able to take a close look at the teeth and surrounding structures with amazing accuracy.
Using digital technology provides nearly 80% less radiation than a standard x-ray. Digital-x-rays include the panoramic, bitewings, and periapical images. The panoramic takes a complete view of the oral cavity. Bitewings (either two or four) are taken to detect decay between the teeth, check margins of existing restorations, and the level of bone surrounding the posterior teeth. Periapical images show the whole tooth from the top of the crown to the tip of the root. These x-rays are beneficial in detecting infections or any root structure abnormalities.
