X-ray safety: Do you know how little radiation a dental X-ray emits?
Dental X-rays are a common procedure in dental offices to diagnose dental and oral health problems. Many patients are concerned about this, fearing the dangers of radiation from X-rays. However, according to experts, the amount of radiation from dental X-rays is actually very small and almost negligible.
Dental X-rays deliver only about 0.150 millisieverts (mSv), which is equivalent to several days of natural background radiation or the amount of radiation you'd receive on a cross-country flight.
Dental X-ray retinoscopy creates images through controlled X-ray radiation that passes through the teeth and surrounding oral structures, producing different images based on the different anatomical densities. Hard teeth appear brighter in the image because they absorb less radiation, while tooth decay, bone loss, or other pathology will appear as darker areas in the image.
To further reduce accidental radiation exposure, most dental offices use lead aprons and lead thyroid collars to protect the rest of the patient's body. At the same time, when operating the X-ray machine, dental technicians will maintain a safe distance while analyzing the images to reduce their own radiation exposure.
To further improve the safety of dental X-ray technology, many clinics today have turned to digital X-ray technology, which not only reduces the amount of radiation required, but also allows for faster image processing, giving patients faster results.
Digital X-ray technology uses electronic sensors to replace traditional imaging films. It can not only capture images in a short time, but also provide real-time viewing, which is very helpful in improving diagnostic efficiency. Although digital sensors are generally more expensive, the quality of information they provide has continued to improve and is becoming increasingly popular in clinics.
Different views and types of dental X-rays
Dental X-rays are taken from a variety of different perspectives and techniques, including intraoral and extraoral views. Intraoral images include root apex images, bitewing images and occlusal images, which are mainly used to check the health of teeth and surrounding bones. Each technology has its specific purpose and indications.
Root apex image
Periapical imaging is mainly used to evaluate the condition of the root apex and surrounding bones, and is suitable for diagnosing problems such as tooth infection or inflammation. Through this image, the dentist can clearly understand the condition of the tooth root and make a more accurate judgment.
Bitewing Image
The purpose of bitewing imaging is to visualize the crowns of the posterior teeth and the height of the gingival bone. In particular, the bitewing view can provide more detailed information when checking whether there are cavities or damage between the teeth.
Occlusal image
The purpose of an occlusal image is to reveal the bony structure of the floor of the mouth or the roof of the mouth. This technique is often used to detect more occult lesions or to confirm the results of other imaging studies.
The use of X-rays and their associated risks
Although dental X-rays are less intensive, excessive or unnecessary radiation can still cause anxiety, which requires the doctor to evaluate and select the appropriate test based on the patient's needs. We recommend that whenever an X-ray is needed, patients should discuss the need and risks with their healthcare provider and express any concerns.
With proper information, patients can make informed choices, reduce unnecessary radiation exposure, and protect their health.
Ultimately, the frequent use of dental X-rays can assist in the diagnosis and treatment of many dental and oral related conditions. Is this enough to make you feel comfortable using dental X-rays?
