SafetyisaPriorityWhenImagingChildrensTeethwithX-Rays

X-ray imaging is a routine part of a child's dental care — and it undeniably makes a difference in preventing and treating dental disease. It's so routine, we can easily forget they're being exposed to an invisible form of electromagnetic radiation.  And just like other sources of radiation, too much x-ray exposure could increase the risk of cancer.

But while it's possible for your child to be over-exposed to x-rays, it's highly unlikely. That's because healthcare professionals like dentists adhere to a standard known as ALARA when considering and administering x-rays. ALARA is an acronym for “as low as reasonably achievable.” In other words, we only want to expose a patient to the lowest and safest levels of x-ray dosage and frequency that will achieve the most benefit.

To achieve that standard, professional dental organizations advocate the use of x-rays only after a clinical examination of the patient, as well as a thorough review of their medical history for any usage of x-rays for other conditions. If x-rays are warranted, we then take further precautions to protect the patient and staff, and only use the type of x-ray application that's absolutely necessary. For most children that will be a set of two or four bitewing radiographs, which are quite effective for detecting decay in back teeth.

This dosage of radiation in a session of bitewing radiographs is roughly a fifth of the background radiation in the environment a child may be exposed to every day. By spacing these sessions at least six months apart, we're able to achieve a high level of decay detection at a safe and reasonable amount of x-ray exposure.

On top of that, the digital advances in x-ray imaging have reduced the amount of radiation energy needed to achieve the same results as we once did with film. These lower exposure levels and the ALARA standard helps ensure your child's exposure to x-rays will be well within safe limits.

BitewingX-RaysanImportantToolinEarlyToothDecayDetection

It's difficult to measure how x-ray imaging has transformed dentistry since its use became prominent a half century ago. As equipment and methods standardized, the technology revolutionized the way we diagnose tooth decay and other mouth-related issues.

One of the more useful of these methods is called the bitewing x-ray. The term comes from the shape of the device a patient holds between their teeth with the film attached on the side toward their tongue. We direct the x-ray beam to the outside of the patient's cheek, where it passes through the teeth to expose on the film. Its particular design provides clearer images since the patient's bite helps keep the film still and distortion-free, making it easier to view signs of early tooth decay.

Bitewing x-rays usually consist of four films, two on either side of the mouth, necessary to capture all of the teeth (children with smaller jaws, however, often only require one film per side). How frequently they're conducted depends on a number of factors, including the patient's age: children or young adolescents are usually filmed more frequently than adults, usually every six to twelve months. Frequency also depends on a patient's particular decay risk — the higher the risk the more frequent the x-ray.

Regardless of how often they're performed, a similar application principle applies with bitewing x-rays as with any other radiological method: As Low As Reasonably Achievable (ALARA). With the ALARA principle in other words, we're looking for that sweet spot where we're able to detect the earliest stages of dental disease with the least amount of radiation exposure.

Bitewings fit this principle well: a patient receives only a fraction of the radiation exposure from a four-film bitewing as they do from a daily dose of environmental radiation. Factor in new digital technology that reduces exposure rates and bitewings pose virtually no health risk to patients, especially if conducted in a prudent manner.

The benefits are well worth it. Thanks to bitewing x-rays we may be able to diagnose decay early and stop it before it causes you or your family member extensive tooth damage.

BitewingX-raysYourQuestionsAnswered

Radiographic (x-ray) images are an indispensible diagnostic tool in dentistry. One of the most routine and useful types of x-rays dentists take is the so-called bitewing. Here are some things you may want to know about this common diagnostic procedure.

What are bitewing x-rays?
Bitewings reveal the presence and extent of decay in the back teeth, specifically in areas where adjacent teeth touch each other. Unlike other areas of the teeth, these contacting surfaces between adjacent teeth can’t be examined visually. Bitewings can also show areas of bone loss around teeth — a sign of periodontal disease; however, they are not taken for that purpose because bitewings will not show the complete root surface that is surrounded by bone.

Why are they called that?
The name “bitewing” refers to how the film — or sensor, in the case of a digital x-ray — is positioned in the mouth: The patient bites down on a little tab or wing that holds the apparatus in place.

How often do I need them?
This is determined on a case-by-case basis, with the goal of not exposing you to any more radiation than necessary — even the minimal amount found in a series of bitewing x-rays. Your individual susceptibility to caries (tooth decay) and personal dental history will play a major role in determining how frequently you need radiographic examination — and, for that matter, how often you need to come in for routine cleanings and exams.

Are they safe?
The safety of bitewing x-rays is best illustrated with a comparison to the regular daily radiation exposure we get every day from environmental sources, which is about 0.01 millisieverts — the unit of measure we use for radiation. A series of 4 bitewing x-rays exposes you to 0.004 millisieverts of radiation — less than half of the daily exposure. Undetected tooth decay, which can spread quickly through the softer inner layers of teeth, is considered much more dangerous!

If a bitewing x-ray shows that there is tooth decay, what happens next?
If the cavity is very small, we may be able to treat it during the same appointment. If not, we will make a separate appointment to make sure it is taken care of promptly. The sooner tooth decay is treated, the better!

Because our main goal is to help you maintain optimal oral health, we use the latest proven technologies, techniques, and treatments to ensure we achieve them. One tool, radiographs or x-ray pictures, has been around for a long time with an inordinate amount of scientific research backing up both its safety and value. Here's a brief summary of why.

X-rays are a form of electromagnetic radiation just like natural daylight, except that they can easily penetrate soft bodily tissues, such as skin and muscles, without causing any harm if used properly. And as you may have guessed, we use them to examine what we can't see with the naked eye. For example, they enable us to see inside tooth structure, bones, and joints of the jaws. This ability makes x-rays a critical tool that we rely upon to monitor your oral health.

How often you need x-rays really depends upon your individual health needs and often is different from family member to family member given their age and oral health. During adolescence, we may need to take x-rays more often, so we can closely monitor the development of the teeth and jaw to check for normal growth and abnormalities, which can be corrected with early diagnosis. We may also need to use x-rays to diagnose trauma if you or any family member has experienced injury or disease. This will enable us to ensure the correct treatment is given and, in fact, is working and that there are no other related concerns.

Today's ultra-sensitive technology uses extremely low dosage x-rays and ensures early diagnosis and monitoring of your oral and dental health in safety and with confidence.
