CTImagingTechnologyCanImproveOutcomesforComplexDentalProblems

The mouth is a crowded place with nerves, blood vessels and sinus cavities sharing common space with the teeth and gums. Although important in their own right, these structures can also hinder treatment for complex dental situations like dental implant surgery or impacted teeth.

Treating these and similar situations depends on getting an accurate depiction of “what lies beneath.” Conventional x-rays help, but their two-dimensional images don't always give the full picture. There's another way—cone beam computed tomography (CBCT).

Similar to CT scanning, CBCT uses x-ray energy to take hundreds of “sliced” images that are then re-assembled with special software to create a three-dimensional model viewable on a computer screen. CBCT is different, though, in that it employs a scanning device that revolves around a patient's head, which emits a cone-shaped beam of x-rays to capture the images.

A dentist can manipulate the resulting 3-D model on screen to study revealed oral structures from various angles to pinpoint potential obstacles like nerves or blood vessels. The detailed model may also aid in uncovering the underlying causes of a jaw joint disorder or sleep apnea.

CT technology isn't the only advanced imaging system used in healthcare. Another is magnetic resonance imaging (MRI), which excites hydrogen atoms in water molecules. This produces different vibration rates in individual tissue structures, which are then translated into detailed images of these structures. Unlike CT or CBCT, MRI doesn't use x-ray energy, but rather a magnetic field and radio waves to produce the atomic vibrations.

But while providing good detail of soft tissues, MRI imaging doesn't perform as well as CBCT with harder tissues like bone or teeth. As to the potential risks of CBCT involving x-ray radiation exposure, dentists follow much the same safety protocols as they do with conventional x-rays. As such, they utilize CBCT only when the benefits far outweigh the potential x-ray exposure risks.

And, CBCT won't be replacing conventional x-rays any time soon—the older technology is often the more practical diagnostic tool for less invasive dental situations. But when a situation requires the most detailed and comprehensive image possible, CBCT can make a big difference.

TheCausesofChronicJawPainMightBeSimilarToFibromyalgia

Chronic joint pain (temporomandibular joint disorder or TMD) in and of itself can make life miserable. But TMD may not be the only debilitating condition you're contending with—it's quite common for TMD patients to also suffer from fibromyalgia.

Fibromyalgia is a condition with a variety of muscular and neurological symptoms like widespread pain, joint stiffness, headaches and tingling sensations. These symptoms can also give rise to sleep and mood disorder, as well as difficulties with memory. Fibromyalgia can occur in both males and females, but like TMD, it's predominant among women, particularly those in their child-bearing years.

In the past, physicians were mystified by these symptoms of body-wide pain that didn't seem to have an apparent cause such as localized nerve damage. But continuing research has produced a workable theory—that fibromyalgia is related to some defect within the brain or spinal cord (the central nervous system), perhaps even on the genetic level.

This has also led researchers to consider that a simultaneous occurrence of TMD and fibromyalgia may not be coincidental—that the same defect causing fibromyalgia may also be responsible for TMD. If this is true, then the development of new treatments based on this understanding could benefit both conditions.

For example, it's been suggested that drugs which relieve neurotransmitter imbalances in the brain may be effective in relieving fibromyalgia pain. If so, they might also have a similar effect on TMD symptoms.

As the study of conditions like fibromyalgia and TMD continues, researchers are hopeful new therapies will arise that benefit treatment for both. In the meantime, there are effective ways to cope with the symptoms of TMD, among them cold and hot therapy for inflamed jaw joints, physical exercises and stress reduction techniques.

The key is to experiment with these and other proven therapies to find the right combination for an individual patient to find noticeable relief. And perhaps one day in the not too distant future, even better treatments may arise.

BuffaloBillsStefonDiggsKnowsTheresNeveraBadPlacetoFloss

Buffalo Bills wide receiver Stefon Diggs wrapped up the NFL regular season in January, setting single-season records in both catches and receiving yards. The Bills handily beat the Miami Dolphins, earning themselves the second seed in the AFC playoffs, and Diggs certainly did his part, making 7 catches for 76 yards. But what set the internet ablaze was not Diggs' accomplishments on the field but rather what the camera caught him doing on the sidelines—flossing his teeth!

The Twitterverse erupted with Bills fans poking fun at Diggs. But Diggs is not ashamed of his good oral hygiene habits, and CBS play-by-play announcer Kevin Harlan expressed his support with “Dental hygiene is something to take note of, kids! There's never a bad place to floss” and “When you lead the NFL in catches and yards, you can floss anytime you want.”

We like to think so. There's an old joke among dentists:
Q. Which teeth do you need to floss?
A. Only the ones you want to keep.

Although this sounds humorous, it is borne out in research. Of note, a 2017 study showed that people who floss have a lower risk of tooth loss over periods of 5 years and 10 years, and a 2020 study found that older adults who flossed lost an average of 1 tooth in 5 years, while those who don't lost around 4 teeth in the same time period.

We in the dental profession stress the importance of flossing as a daily habit—and Stefon Diggs would likely agree—yet fewer than 1 in 3 Americans floss every day. The 2016 National Health and Nutrition Examination Survey (NHANES), conducted by the CDC's National Center for Health Statistics, revealed that only 30% of Americans floss every day, while 37% floss less than every day and 32% never floss.

The biggest enemy on the football field may be the opposing team, but the biggest enemy to your oral health is plaque, a sticky film of bacteria and food debris that builds up on tooth surfaces. Plaque can cause tooth decay and gum disease, the number one cause of tooth loss among adults. Flossing is necessary to remove plaque from between teeth and around the gums where a toothbrush can't reach. If not removed, plaque hardens into tartar, which can only be removed by the specialized tools used in the dental office. Regular professional dental cleanings are also needed to get at those hard-to-reach spots you may have missed.

If Diggs can find time to floss during a major NFL game, the rest of us can certainly find a couple minutes a day to do it. While we might not recommend Diggs' technique of flossing from one side of the mouth to the other, we commend his enthusiasm and commitment to keeping his teeth and gums healthy. Along with good dental hygiene at home—or on the sidelines if you are Stefon Diggs—regular professional dental cleanings and checkups play a key role in maintaining a healthy smile for life.
