Our pediatric dental office exclusively uses digital x-rays (digital radiography) for all patient visits. Digital x-rays are commonly used at most offices but for pediatric practices it has many advantages.
The x-ray film that has been used in the past uses a much higher dosage of radiation when compared to digital x-rays. Digital x-rays use up to 90% less radiation and also produce higher detailed images for the dentist to study. This is very important when we are working with our little ones. We want to make sure that we take radiographs quickly and that we have images that are clear – even if our little patient is a bit wiggly!
Other advantages of digital x-rays at the dentist office:
Aside from the clear safety benefits, one of the other greatest assets to using digital x-rays is the same advantage digital cameras had over traditional cameras when they first came out: instantaneous review.
Because the images can be immediately reviewed on a computer screen and expanded or highlighted to view particular areas, it makes for much more efficient diagnosis and input. We are able to magnify the x-ray to see areas that may be difficult to see. It also makes storing the x-rays in the patient’s file much easier — especially in cases where your dentist needs to send that information to another health professional. Older film x-rays are very difficult to store, mail and to view with the naked eye. Digital x-rays tend to have a higher dynamic range in the image, meaning that the difference between light and dark areas is more pronounced. This makes spotting small details easier.
Digital x-rays are captured much faster than x-rays that involve film. Thin phosphoric plate sensors are positioned inside your child’s mouth, which are smaller and easier for a child’s mouth. The small sensor, quick exposure and one-step processing makes digital x-rays safer and quicker for our staff and your child. Instead of using chemicals for development, a digital x-rays is captured instantly so we can immediately see your child’s x-ray. Another advantage when we are working with our young patients.
How digital x-rays help dentists:
Dental x-rays are used to give us the full picture of what is going on with your child’s teeth. Because we can’t see everything that we need to see with the naked eye, x-rays help us to see important things that help us to treat your child accurately.
If your child is three years old or older we will recommend that your child have digital x-rays taken by our staff. Those x-rays will help us to identify critical information such as
- Cavities or tooth decay
- Traumatized teeth
- Underlying adult teeth
- Missing or extra teeth
- Tumors or growths that may affect your child’s development
- The position and spacing of your child’s teeth for braces
Types of digital x-rays dentists use:
There isn’t just one type of dental x-ray used to help your child. Pediatric dentists can take digital x-rays in different areas in order to examine the mouth for specific things. We’ll outline those below.
Occlusal x-rays: These x-rays are performed on a child’s front teeth. This x-ray is super simple to take and help us to see a child’s front baby and adult teeth. It is most useful when a child has fallen on the front teeth. This is also one of the first x-rays that your child will have. It is a great way to ease them into taking x-rays!
Bitewing x-rays: This type of x-ray involves the patient biting down on a piece of paper so that we can see any between-the-teeth cavities that might exist. We recommend that your child have these x-rays taken once every year. Some children may need to have these x-rays every six months if they have teeth that are very close together and prone to between-the-teeth cavities. We will let you know if your child would benefit from more frequent bitewing x-rays.
Panoramic x-rays: This type of x-ray rotates around the patient’s head, and is commonly used to check for jaw growth, missing teeth, extra teeth, wisdom teeth, check for jaw problems and the first step in assessing if your child may need braces. This picture is taken when your child is between 7 and 9 years old. We only take these pictures every 5 years.
Periapical x-rays: This x-ray technique is more of a close up, focusing on 1 or 2 teeth from root to crown. This type of x-ray allows for a very detailed look at those teeth in particular. We take these teeth as needed if your child has a problem or pain with a particular tooth.
