X-rays revolutionized dental care in the 20th Century. The same could happen in the 21st Century as cone beam computed tomography (CBCT) becomes a fixture beside the traditional x-ray machine.
CBCT made its debut in dental offices about a decade and a half ago. It utilizes the same invisible energy as traditional x-rays to create images of the face and jaw. But unlike traditional x-rays, which can only depict structures in the two dimensions of width and height, CBCT can create three-dimensional images in amazing detail.
The CBCT's x-ray projector rotates around a patient's head. As it emits a cone-shaped beam of x-rays, the device simultaneously collects anywhere from 150 to 599 distinct image views. It transmits these views to a computer that assembles them into three-dimensional images that can be viewed on a computer display.
From the data file of images, dentists can re-format a variety of views and angles of teeth, jaws and other facial bones at various levels of magnification. Because of this wide range of views, all in striking detail, CBCTs are highly useful among other things for diagnosis of malocclusions (bad bites), the size and location of infections, obstructions at possible implant sites, or jaw problems prior to surgery.
Because they expose a patient to higher doses of radiation than a standard x-ray machine, they're normally limited to more complex oral situations. That means you'll still undergo standard x-rays for most of your dental treatment needs. CBCT radiation levels are lower, however, than medical CT scans, which use a fan-shaped beam that can expose a patient to ten times the radiation of a CBCT. For dental care, a CBCT machine also produces greater image detail than an MRI.
Depending on your needs, CBCT may one day be a part of your dental care.Â With their range and accuracy, it could play a major role in helping you attain good health.

Can you have healthy teeth and still have gum disease? Absolutely! And if you don’t believe us, just ask actor David Ramsey. The cast member of TV hits such as Dexter and Arrow said in a recent interview that up to the present day, he has never had a single cavity. Yet at a routine dental visit during his college years, Ramsey’s dentist pointed out how easily his gums bled during the exam. This was an early sign of periodontal (gum) disease, the dentist told him.
“I learned that just because you don’t have cavities, doesn’t mean you don’t have periodontal disease,” Ramsey said.
Apparently, Ramsey had always been very conscientious about brushing his teeth but he never flossed them.
“This isn’t just some strange phenomenon that exists just in my house — a lot of people who brush don’t really floss,” he noted.
Unfortunately, that’s true — and we’d certainly like to change it. So why is flossing so important?
Oral diseases such as tooth decay and periodontal disease often start when dental plaque, a bacteria-laden film that collects on teeth, is allowed to build up. These sticky deposits can harden into a substance called tartar or calculus, which is irritating to the gums and must be removed during a professional teeth cleaning.
Brushing teeth is one way to remove soft plaque, but it is not effective at reaching bacteria or food debris between teeth. That’s where flossing comes in. Floss can fit into spaces that your toothbrush never reaches. In fact, if you don’t floss, you’re leaving about a thirdÂ to half of your tooth surfaces unclean — and, as David Ramsey found out, that’s a path to periodontal disease.
Since then, however, Ramsey has become a meticulous flosser, and he proudly notes that the long-ago dental appointment “was the last we heard of any type of gum disease.”
Let that be the same for you! Just remember to brush and floss, eat a good diet low in sugar, and come in to the dental office for regular professional cleanings.
