Understanding OPG (Orthopantomogram): Purpose, Procedure, and Benefits

What is OPG (Orthopantomogram)?

An OPG, or Orthopantomogram, is a special type of dental X-ray. It shows a wide view of your jaws, teeth, and surrounding bones. Many dentists and radiologists use OPG scans to check for dental problems. This dental X-ray OPG helps spot issues that may not be seen with a regular X-ray. Because it covers both jaws in one image, it is very useful for dental care.

Why is OPG Done? (Purpose and Indications)

Often, dentists order an OPG scan for several reasons. For example, it helps to:

Check for tooth decay, gum disease, or infections

See the position of wisdom teeth

Plan for braces or dental implants

Detect jawbone problems or cysts

Spot fractures or injuries to the jaw

Additionally, an orthopantomogram procedure can help find hidden dental issues. It is also used before some surgeries or treatments. According to the World Health Organization, dental X-rays like OPG are safe and helpful for diagnosis.

How is an OPG Performed? (Procedure and Patient Experience)

First, you will be asked to stand or sit in front of the OPG machine. Next, a technician will help you place your chin on a small rest. You may need to bite gently on a plastic piece to keep your mouth steady. Then, the machine will move around your head. It takes a picture of your jaws in just a few seconds. You will not feel any pain during the OPG scan. The whole process usually takes less than 10 minutes.

Benefits and Advantages of OPG

There are many OPG benefits for both patients and doctors. Some of the main advantages include:

Shows both jaws and all teeth in one image

Quick and painless procedure

Helps detect hidden dental problems

Useful for planning dental treatments

Low radiation compared to some other X-rays

Because of these benefits, OPG scans are a popular choice in dental clinics.

Safety and Risks of OPG

Most people can safely have an OPG scan. The amount of radiation is very low. In fact, it is much less than a chest X-ray. However, pregnant women should tell their doctor before the scan. Sometimes, your doctor may suggest waiting until after pregnancy. According to the CDC, dental X-rays are safe when used properly. Still, always follow your dentist’s advice.

How to Prepare for an OPG

Preparing for an OPG scan is simple. Usually, you do not need to fast or change your routine. However, you should:

Remove any jewelry, glasses, or metal objects from your head and neck

Tell the technician if you are pregnant or think you might be

Follow any special instructions from your dentist or radiologist

Because the procedure is quick, you can return to your normal activities right after.

What to Expect After the Procedure

After your OPG scan, you can go home or back to work right away. There is no recovery time needed. Your dentist or radiologist will review the images. Then, they will discuss the results with you. If any problems are found, your doctor will explain the next steps. Most people do not have any side effects from an OPG scan.
