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.

EatingtheRightFoodsCanBoostYourEffortstoPreventDentalDisease

You're more apt to lose teeth because of periodontal (gum) disease and tooth decay than any other cause. But neither of these bacterial diseases have to happen: You can prevent them through daily brushing and flossing and twice-a-year dental cleanings.

But that's not all: You can also boost your dental care practices by eating foods that strengthen and protect teeth. On the other hand, a poor diet could reduce the effectiveness of your oral hygiene practices in preventing tooth decay or gum disease.

A diet that might lead to the latter is often high in refined sugar (sucrose), often added to processed foods and snacks to improve taste. But sucrose is also a top food source for oral bacteria, increasing their numbers when it's readily available. A higher bacterial population greatly increases your risk for tooth decay or gum disease.

On the other hand, certain foods benefit your overall dental health. Fresh fruits and vegetables, for example, are filled with nutrients and minerals like vitamin D or calcium that strengthen teeth against disease. And although they can also contain natural sugars, these don't pose the same problems as added sucrose due to the plant fiber you consume with them.

Dairy foods can also help you maintain healthy teeth and gums. Milk and cheese contain minerals like calcium and phosphorus, and a protein called casein, all of which strengthen teeth against decay. The enzymes in cheese stimulate saliva, which in turn neutralizes mouth acid and prevent it from harming enamel.

Some foods are also natural sources of fluoride, a mineral that strengthens tooth enamel. One example is black tea, which also, along with green tea, contains antioxidants that protect against cancer.

The best strategy for “tooth-friendly” nutrition is to pursue a diet that's high in fiber-rich natural foods and low in sugar-added processed foods. In practice, you'll want most of your diet to consist of fresh fruits and vegetables and low-fat dairy food, while minimizing foods with added sugar.

Following this kind of diet will certainly benefit your overall health. But it will also make it easier for you to prevent dental disease and keep your teeth and gums healthy.

YouCanHaveaStraighterSmile-JustLiketheQueenofEngland

The monarchs of the world experience the same health issues as their subjects—but they often tend to be hush-hush about it. Recently, though, the normally reticent Queen Elizabeth II let some young dental patients in on a lesser known fact about Her Majesty's teeth.

While touring a new dental hospital, the queen told some children being fitted for braces that she too “had wires” once upon a time. She also said, “I think it's worth it in the end.”

The queen isn't the only member of the House of Windsor to need help with a poor bite. Both Princes William and Harry have worn braces, as have other members of the royal family. A propensity for overbites, underbites and other malocclusions (poor bites) can indeed pass down through families, whether of noble or common lineage.

Fortunately, there are many ways to correct congenital malocclusions, depending on their type and severity. Here are 3 of them.

Braces and clear aligners. Braces are the tried and true way to straighten misaligned teeth, while the clear aligner method—removable plastic mouth trays—is the relative “new kid on the block.” Braces are indeed effective for a wide range of malocclusions, but their wires and brackets make it difficult to brush and floss, and they're not particularly attractive. Clear aligners solve both of these issues, though they may not handle more complex malocclusions as well as braces.

Palatal expanders. When the upper jaw develops too narrowly, a malocclusion may result from teeth crowding into too small a space. But before the upper jaw bones fuse together in late childhood, orthodontists can fit a device called a palatal expander inside the upper teeth, which exerts gentle outward pressure on the teeth. This encourages more bone growth in the center to widen the jaw and help prevent a difficult malocclusion from forming.

Specialized braces for impacted teeth. An impacted tooth, which remains partially or completely hidden in the gums, can impede dental health, function and appearance. But we may be able to coax some impacted teeth like the front canines into full eruption. This requires a special orthodontic technique in which a bracket is surgically attached to the impacted tooth's crown. A chain connected to the bracket is then looped over other orthodontic hardware to gradually pull the tooth down where it should be.

Although some techniques like palatal expanders are best undertaken in early dental development, people of any age and reasonably good health can have a problem bite corrected with other methods. If you are among those who benefit from orthodontics, you'll have something in common with the Sovereign of the British Isles: a healthy, attractive and straighter smile.
