Digital Dental X-Rays

Using DEXIS™ technology, Rosenberg Family Dentistry is able to provide safe, more accurate diagnoses using digital dental X-rays in St. John and Great Bend, Kansas. Dr. Joe Rosenberg uses this imaging system to help identify problems early before they develop into more serious issues. Visit our dentist for a general exam and see how we use the latest technology to help you.

Digital X-rays are one of the advanced diagnostic tools we use to provide you with the best possible care. Digital radiography has changed the way we take dental X-rays by making the process faster, more comfortable and more convenient than ever before. Digital X-rays use a digital sensor to take images of your teeth, unlike traditional X-rays that use film. Digital X-rays use significantly less radiation than conventional film X-rays and require the use of no chemicals for developing the images. Our dentist can then instantly view the high-quality images on monitors right in the treatment room to provide you with efficient, accurate diagnoses and care. Our team is able to use digital radiography to identify and diagnose several types of dental problems, such as:

  • Decay in between teeth

  • Developmental abnormalities

  • Improper tooth root positioning

  • Cysts and abscesses

  • Fractures in existing fillings

  • Tumors

  • Infection in the tooth nerves

  • Bone loss

Digital dental X-rays are used to plan many kinds of dental treatment, such as oral surgery procedures, root canal treatment, dental implants, orthodontics and more. To learn more about digital radiography and how we use X-rays at our office, we welcome you to call or visit us soon.


How much radiation am I being exposed to with a dental xray? 


Radiation is measured in a unit known as millirems (mrem). The following is a list that can help put dental x-rays in perspective:

  • 1 mrem = two hours in a jet plane

  • 7 mrem/year = from living in a brick house

  • 700 mrem = abdominal x-ray

  • 0.5 mrem = one “regular” dental x-ray (traditional wet film)

  • 0.1 mrem = one digital x-ray (what we use)

So as you can see from the chart above, dental x-rays are a very low source of radiation. Also, notice that digital dental x-rays reduce radiation by 70-80% further to only about 0.1 mrem! 

Therefore, in addition to limiting the number of x-rays we take, we are using the best technology possible to minimize the dose to the lowest possible level.


Dental x-rays are just another tool in the oral care arsenal. The cleaning and visual examination of your teeth, gums, and the rest of your mouth serve to keep the exposed portions of your mouth healthy.

However, a lot can go on beneath the gum line or inside of teeth themselves that dentists cannot see without x-rays. While you might wonder why you need x-rays when there’s no outward indication that something is wrong, this tool can provide early warning of potential problems (like small cavities), allowing for treatment before they become much bigger issues.


The frequency of x-rays varies by dental office and by patient. Some patients may only need x-rays annually, while others need them every six months, or even more frequently, depending on developing conditions.

Dentists make careful assessments about if and when patients need x-rays, carefully weighing the benefits and potential risks before deciding on any tests or courses of treatment. If x-rays are recommended, it is likely with good reason.
