This is a good article that highlights many of the issues relevant to dental x-rays. A few thoughts:
1. X-rays provide valuable diagnostic information. X-rays have always allowed dentists to identify issues such as cavities, gum disease and developmental dental problems at a point where they can be successfully treated with minimal and conservative dental treatment.
2. Radiation should be avoided in all forms, and dental x-rays must always be used only after evaluating the cost vs. benefit to the patient. All professionals should follow ALARA guidelines or As Low As Reasonably Achievable. But, it is important to have perspective when evaluating the radiation associated with dental x-rays to the typical background radiation experienced by all of us on a daily basis. A day at the beach or a flight from New York to LA will expose a person to significantly more radiation than patients will experience in a dental office. http://www.radiologyinfo.org/en/pdf/safety-xray.pdf
3. Beyond this, Ferguson Dental is committed to providing patients with the safest, most advanced technology available. Digital dental x-rays expose patients to a 1/5th of the radiation experienced from film x-rays, and we have provided digital dental x-rays for our patients for over 20 years. Additionally, our new extra-oral x-ray machine provides us with the option of ultralow dose panoramic x-rays and ct scans. This technology provides, again, significantly lower radiation dose x-rays compared to film panoramic x-rays or medical CT scans. Using our advanced technology, we are able to see more with less radiation than conventional full mouth radiographic imaging.
4. Most importantly, we work with every patient and parent to assess individual disease risk before determining the proper interval of dental x-rays. We are committed to minimizing radiation dose while also maintaining dental health.
5. Choosing dental care based upon what dental insurance will cover is not advisable and that approach is not found at Ferguson Dental. We recommend and implement dental protocols on an individual basis given the specific needs of every patient. We are absolutely committed to your dental and overall health. Please always feel free to ask us more about any issue that concerns you!
