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.

SupermodelAshleyGrahamsUnpleasantDentalEncounterWithaFrozenCookie

Ashley Graham has a beautiful and valuable smile—an important asset to her bustling career as a plus-size model and television host. But she recently revealed on Instagram a “confrontation” between one of her teeth and a frozen oatmeal cookie. The cookie won.

Holding her hand over her mouth during the video until the last moment, Graham explained how she sneaked a cookie from her mom's freezer and took a bite of the frozen treat. Taking her hand from her mouth, she revealed her broken tooth.

Okay, maybe it wasn't an actual tooth that was broken: the denticle in question appeared to have been previously altered to accommodate a porcelain veneer or crown. But whatever was once there wasn't there anymore.

Although her smile was restored without too much fuss, Graham's experience is still a cautionary tale for anyone with dental work (and kudos to her for being a good sport and sharing it). Although dental work in general is quite durable, it is not immune to damage. Biting down on something hard, even as delicious as one of mom's frozen oatmeal cookies, could run you the risk of popping off a veneer or loosening a crown.

To paraphrase an old saying: Take care of your dental work, and it will take care of you. Don't use your teeth in ways that put your dental work at risk, tempting as it may be given your mouth's mechanical capabilities.

 Even so, it's unwise—both for dental work and for natural teeth—to use your teeth and jaws for tasks like cracking nuts or prying open containers. You should also avoid biting into foods or substances with hard textures like ice or a rock-hard cookie from the freezer, especially if you have veneers or other cosmetic improvements.

It's equally important to clean your mouth daily, and undergo professional cleanings at least twice a year. That might not seem so important at first since disease-causing organisms won't infect your dental work's nonliving materials. But infection can wreak havoc on natural tissues like gums, remaining teeth or underlying bone that together often support dental enhancements. Losing that support could lead to losing your dental work.

And it's always a good idea to have dental work, particularly dentures, checked regularly. Conditions in the mouth can change, sometimes without you noticing them, so periodic examinations by a trained dental provider could prevent or treat a problem before it adversely affects your dental work.

We're glad Ashley Graham's trademark smile wasn't permanently harmed by that frozen cookie, and yours probably wouldn't be either in a similar situation. But don't take any chances, and follow these common sense tips for protecting your dental work.

3SeasonsofaWomansLifeThatCouldPresentNewOralHealthChallenges

May 9-15 is National Women's Health Week, which begins each year on Mother's Day. It's an important opportunity to focus on the unique health challenges women face, and ways to better meet those challenges. Among the many health aspects that deserve attention, one of the most important is the health of a woman's teeth and gums over the course of her life.

Although preventing and treating dental disease remains a primary focus throughout life, women do face a number of different situations during various life stages that often require additional attention. Here are 3 such life moments for a woman that may give rise to oral and dental problems.

Adolescence. The changes that occur in their physical bodies as girls enter puberty may make their gums more sensitive to bacterial plaque, a thin biofilm that forms on teeth. This can cause painful swelling, a condition that may become even more acute if they wear braces. To counteract this, it's important for girls in their teens to not neglect daily brushing and flossing to remove excess plaque, and to make regular dental visits at least every six months.

Pregnancy. Each of the estimated 40 million U.S. women who have given birth share a common experience—they've all undergone the hormonal changes that accompany pregnancy. Such changes can adversely affect dental health: The hormonal shifts, and the sugar cravings that often accompany them, increase the risk for dental disease, especially gum infections. As with adolescence, daily oral hygiene and regular dental visits (as well as a healthy diet) are important for staying a step ahead of possible tooth decay or gum disease.

Menopause. Women in menopause or who have passed through it can encounter new oral problems. Persistent dry mouth caused by a lack of adequate saliva flow, for example, can cause irritation and significantly increase the risk of dental disease. Osteoporosis and some medications for its treatment could also interfere with dental care. Besides daily oral hygiene, older women can ease dry mouth symptoms with saliva boosters or drinking more water. They should also work with their physicians to minimize any oral effects from their medications.

Many aspects of dental care remain constant regardless of a woman's season of life. Daily oral hygiene should be a lifetime habit, as well as seeing a dentist at least twice a year. But there are times when a unique stage of life requires something more—and it's always better to be proactive rather than reactive in meeting new challenges to oral health.
