What is an OPG X-ray?

An OPG (Orthopantomagram) is a panoramic scanning dental X-ray of the upper and lower jaw which shows a flattened two dimensional view from both ears and shows the maxilla (upper jaw) and mandible (lower jaw).

At some stage in your dental treatment, your dentist will likely take an OPG, and any specialist referral will require an up to date OPG X-ray.

An OPG shows the number, position and growth of all the teeth including those that have not yet surfaced or erupted through the gum. It is different from the small close up x-rays dentists take of individual teeth, with less fine detail, but a much broader area of view, which can be important when checking hard to see areas like wisdom teeth formation, or the development of a child’s jaw and teeth. It is also often used to check your jaw joint, the TMJ (temporomandibular joint), checks for any possible pathology, and sometimes identifies a tooth that is damaged into the bone, before it becomes a toothache.

Where can I get an OPG taken?

Brisbane Smile Boutqiuel has a OPG machine on site for your convenience. and the images are produced digitally and recorded in your electronic file with all your other x-rays and images. The image is produced within seconds of the OPG being taken and your dentist will review it with you at the end of the appointment.  An OPG is just one diagnostic tool your dentist will use to maintain your dental health and prevent unnecessary dental issues arising.

REASONS FOR OPG X-rays

  • Broad coverage of facial bones and teeth including the TMJ (temperomandibular joint)

  • Low patient radiation dose

  • Convenience of examination for the patient

  • Ability to be used in patients who are restricted in opening their mouth

  • Very short time required for producing the image

Your dentist will ask you to remove any jewellery or metallic items from around the head and neck area as it can interfere with the image, blocking the x-ray. The OPG usually takes about 5 mins to complete, with the actual image taking just 14 seconds.
