About OPG & Lat Ceph

An OPG (orthopantomogram) is a radiology modality that provides a panoramic x-ray of the upper and lower jaw including the teeth, maxillary sinuses, and temporomandibular joints. OPGs may be used to assess:

  • Dental pain
  • Periodontal bone loss (bone loss around teeth and in the jaw)
  • Orthodontic assessment
  • Wisdom teeth
  • Temporomandibular joints
  • Number and position of erupted and unerupted teeth

A Lat Ceph (Lateral Cephalogram) is a dental image taken from the side of the face. This image is used to take various measurements to determine and assess the current and future relationship of the upper and lower jaw and assess your bite. This is very useful in planning of orthodontic treatment.

Your appointment and preparation

A referral from a doctor is required for OPG & Let Ceph examinations.

No appointment is necessary.

What can I expect during my OPG?

You will be asked to remove any jewellery or metal objects in the region of the head and face before the examination.

Our radiographer will take your images with a specially designed dental imaging machine. You will be asked to stand side on to the machine and be positioned within a head holder which will hold your head in the correct position for the images. The radiographer will ask you to bite your teeth together, and then take the image. The procedure takes only a few seconds. Sometimes your dental specialist may ask for different views, using the same machine. For example requiring you to face the machine, still using the head holder.

What are the risks and side effects?

OPG & Lat Ceph involve a small dose of radiation. At Lake Imaging you can be assured that by using the latest technology and with staff trained in radiation reduction techniques, radiation doses are kept as low as reasonably possible.

If it is possible that you may be pregnant, please tell our radiology team before your x-rays are taken to avoid any risks to your unborn child.

Who will perform my OPG and write the report?

At Lake Imaging your examination will be carried out by a Radiographer (or Medical Imaging Technologist), who has a degree in Medical Imaging and is accredited by the Australian Institute of Radiography. Our Radiologist, a medical Doctor specialising in the interpretation of medical images, will produce a report for your referring doctor detailing the findings of your examination.

How do I obtain my results?

The radiographer will give you a copy of your OPG or Lat Ceph to take back to your referring dental specialist, who will review your images for your dental care. A report will also be provided by our reporting doctor within 48 hours of your images being taken.

Please ensure that you make a follow up appointment with your referring doctor or health care provider to discuss your results.
