LamarOdomReboundsFromDentalAnxiety

Professional basketball player Lamar Odom is sometimes known as “the candyman” because of his notorious fondness for sweets. But when his sweet tooth finally caught up with him — in the form of a mouthful of decayed teeth — the six-foot-ten-inch, 230-pound hoops star admitted that he had been avoiding treatment… because he was afraid of going to the dentist!

It took two Kardashians (Khloe and Kim) and a painful toothache to finally persuade Odom to sit in the chair. Once he did, it was found that he needed a root canal, a wisdom tooth extraction, and several fillings. Yet the fretful forward sailed through the whole set of procedures in a single visit, and walked out with a big smile afterward. How did his dentists make that happen?

Put it down to the “magic” of sedation dentistry. With anxiety-relieving medications that can be delivered orally (in pill form or by gas) or intravenously (into the bloodstream), the techniques of sedation dentistry can help even the most fearful patients get the dental care they need. That’s good news for about 50 percent of the population, who admit they’re at least somewhat afraid of the dentist — and even better for the 15 percent who avoid dental care completely due to their fear.

Dentists have a number of ways to ease apprehensive patients through a dental visit. An oral anti-anxiety drug can be given in pill form about an hour beforehand. Nitrous oxide (sometimes called “laughing gas”), which is administered by a mask placed over the mouth or nose, may also be used to relieve anxiety. The calming effects of these medications help make any nervousness melt away — and in many circumstances, mild sedation is all that’s needed to ease the fear.

For lengthier or more complex procedures, intravenous (IV) sedation may be recommended. Unlike deeper (unconscious) sedation, IV sedation doesn’t cause “sleep.” Instead, it puts you in a comfortable semi-awake state, where you can still breathe on your own and respond to stimuli… but without feeling any anxiety. And when the procedure is over, you probably won’t have any memory of it at all.

IV sedation can be administered by dentists who are specially trained and equipped with the proper safety equipment. While sedation is being provided, you will be monitored at all times by a dedicated staff member; when it’s over, you will rest for a while as the medication quickly wears off. Then (as is the case with oral sedation), you’ll need another person to give you a ride home.

Does sedation dentistry really work? Lamar Odom thinks so. “I feel so much better,” he said when his 7-hour procedure was over. “I feel like I accomplished something.”

X-RayRadiationExposureisMuchLessthanDailyEnvironmentalRadiation

X-rays are an important diagnostic tool in dentistry because of their ability to penetrate and pass through body tissues. Because they penetrate at different speeds depending on tissue density (shorter and thus darker on exposed film for soft tissues, longer and lighter for hard tissues like bone or teeth), we’re able to detect decay which appear as dark areas on x-ray film.

Without x-rays, the early detection and diagnosis of dental problems would be quite difficult. But despite its obvious benefits, it’s still a form of released energy that exposes patients to a certain amount of radiation. Since the potential health risk from radiation depends on the amount released (the dosage) and for how long and often a person is exposed, we must determine if the dosage and frequency from dental x-rays is a cause for concern.

It’s a common misconception to view any radiation exposure as dangerous. The truth is, however, we’re all exposed daily to radiation from the natural environment — about 2 to 4.5 millisieverts (the dosage measurement for radiation exposure) a year, or about 10 microsieverts (one-thousandth of a millisievert) every day.

In comparison, radiation exposure from routine dental x-rays is a fraction of this if measured over time. A set of four bitewing images of the back teeth produces 4 microsieverts of radiation, less than half the average daily exposure. One of the most comprehensive x-ray sets, a full mouth series of 18-20 images using “D” speed film, results in an exposure of 85 microsieverts, equaling about a week of normal radiation exposure.

These thoroughly researched rates help demonstrate that regular dental x-rays are relatively safe. What’s more, x-ray technology has continued to advance since first used in the mid-20th Century. With innovations in film and digital processing, today’s equipment produces only 80% of the radiation exposure of earlier machines. In effect, we’ve increased our capabilities to more accurately detect and diagnose issues through x-rays, while lowering the amount of radiation exposure.

Of course, a person’s annual exposure rate may differ from others. If you have concerns for yourself or your family about x-ray radiation exposure, please feel free to discuss this with us. Our primary goal is to improve your oral health without undue risk to your health in general.
