Recently in the news we have heard about a study in the Cancer Journal, about a possible link between dental x-rays and brain tumors. I have had a number of people come into my office asking about this study and what my opinion is. The American Dental Association has posted some great information about the study that I will relay in this blog.
It is my opinion that we need to be careful not to overreact when when we hear information such as this. One study doesn’t give us all we need to know. As you know, quality clinicians use a compilation of studies to make diagnosis recommendations for our patients. Dental x-rays have been used for decades for our patients and have done so much good for helping all of us save our teeth. We
must not forget about the positive aspects of dental x-rays. If you are reading this, you probably have a tooth in your mouth that was saved because our Centennial dentists took an xray of your teeth.
Below are a few items from the ADA about what their Division of Science stated after reviewing the study.
1 – The findings of this study are based on patient recall of X-rays taken years ago and peoples memories can be unreliable.
2 – Advances in X-ray technology, equipment improvements, faster film speeds, and digital x-rays have successfully reduced the radiation exposure.
3 – The study was observational, meaning it cannot establish a cause-and-effect relationship between dental x-rays and brain tumors.
4 – The results of the study did not appear to be dose-related as would be expected.
Five to seven years ago we invested in digital x-rays which have 50-75% less radiation than the old style of film x-rays. We also invested in lead aprons with thyroid collars, to protect your thyroid and other glands of your neck. We invested in both of these long before this, and many other studies were published. At Rocky Mountain Dental Partners strive to provide you with the highest-quality dental care available for you and your family.
I hope this helps clarify a few items from this study and from the latest news releases.
