It's almost impossible to imagine the practice of dentistry without x-ray technology. Radiographs (x-ray pictures) allow dentists to diagnose and treat problems not yet visible to the naked eye, including early tooth decay, gum disease, abscesses and abnormal growths. There is no question that since x-rays first became available a century ago, this diagnostic tool has prevented untold suffering and saved countless teeth. Now, state-of-the-art digital x-rays have made the technology even safer and more beneficial.
Digital x-ray technology uses a small electronic sensor placed in the mouth to capture an image, which can be called up instantly on a computer screen. When digital x-rays first became available about 20 years ago, they immediately offered a host of advantages over traditional x-ray films, which require chemical processing. Most importantly, they cut the amount of radiation exposure to the dental patient by as much as 90%. While faster x-ray films have been developed over the years that require less exposure, making that difference less dramatic, a digital x-ray still offers the lowest radiation dose possible.
Advantages of Digital X-Rays
Besides minimizing radiation exposure, digital x-rays offer numerous advantages to dentists and patients alike. These include:
- No chemical processing & no waiting. Because there is no film to process with digital x-rays, there is no waiting for pictures to develop — and no toxic chemicals to dispose of. Your dentist can immediately show you the pictures on a computer screen for easy viewing.
- A clearer picture. It's possible to get more information from digital x-rays because they are sharper and can be enhanced in a number of ways. The contrast can be increased or decreased, and areas of concern can be magnified. It's even possible to compare them on-screen to your previous x-rays, making even the minutest changes to your tooth structure easier to detect.
- Easy sharing and storage. Digital x-rays provide a better visual aide for you, the patient, to understand your diagnosis and treatment options. They can be e-mailed to different locations; they are also far less likely to be misplaced.
X-Ray Safety For Children Nearly every diagnostic testing procedure carries some risk, so it's always important for you and your healthcare provider to weigh the benefits against the risks. This is particularly true when it comes to children, who are more sensitive to x-rays than adults... Read Article
Getting The Full Picture With Cone Beam Dental Scans Dental imaging took a major leap forward at the beginning of the new millennium with a three-dimensional technology known as cone beam computed tomography (CBCT). The name comes from the cone-shaped beam of x-rays the CBCT machine projects as it rotates around a person's head, taking multiple images that are compiled into a 3-D picture by a computer. Find out what CBCT can reveal and how it helps a doctor to make a highly informed diagnosis and choice of treatment... Read Article
