Why Use Digital X-Rays
Digital x-rays require less radiation, enable better storage and rely less on toxic chemicals. The 3D CBCT technology allows us to give better diagnosis because the high-tech software enables us to manipulate images making calculations easier.
In 2010, it was unheard of for general dentists to routinely use this technology. It was more commonly used for dental implant cases or oral surgery. However, seeing how the technology can improve diagnosis and subsequently patient care, it was an investment our office had to make. Since then, Dr. Marvin has reviewed and evaluated more CBCT scans than most practitioners which makes him highly reliable in taking and analyzing your CBCT radiographs.
Is It Safe?
Like all things in this world, CBCT or any other x-ray for that matter have inherent risks. Believe us when we say we do not take the decision to take an x-ray lightly. Everyday, we are all exposed to radiation, so adding more radiation to your body’s burden is something Dr. Marvin always takes into account. When we recommend for you to take a CBCT X-ray, it is because the rewards far exceed the risks.
How Much Radiation DO I Get With Each Scan?
The machine puts out between 23-103 mirosiverts depending on the size of the person. For your reference, a person flying coast-to-coast will be exposed to 50 microsiverts. At most, one CBCT X-ray is equivalent to a round trip flight from San Diego to New York.
How Often Do We Request X-Rays?
We would normally like to do 1 CBCT scan at the initial appointment unless you have had a scan within 3 months of your appointment. We recommend taking a scan every 3-5 years unless there is a need to take them sooner.
Why 3D Imaging Over Regular Dental X-rays
A CBCT can show you the actual size of a tooth abscess versus a typical x-ray that shows you a flattened view. This then helps in locating a problem better so as to guide the surgeon to remove ALL the infection. This makes it a more secure way in approaching a procedure.
A 2-Dimensional Image
These images are examples of what a wisdom tooth looks like forma panoramic x-ray versus a CBCTx-ray.
Observe how the wisdom tooth seems to be right on top of the nerve bundle when viewed from the 2D panoramic x-ray. When viewed from the CBCT image, you will see that the wisdom tooth is actually to the cheek side. Now wouldn’t you feel more comfortable knowing that your surgeon taking out your tooth knows where the delicate nerve is in relation to the tooth being removed?
A 3-Dimensional Image
The advantage of a 3D CBCT scan is that you are able to take more thin “slices” of data. A 2D bitewing or panoramic x-ray only takes a limited number of slices, thus putting the clinician at a disadvantage. Naturally, having more data on hand gives a clinician more confidence in providing better diagnosis and a subsequent treatment plan.
