OPG (Orthopantomogram) and Cephalogram are types of dental X-rays. An OPG produces a panoramic view of the jaw whilst a Cephalogram is an X-ray of the facial structures. A lateral Cephalogram produces a side profile image of the face, jaws and soft tissues to assess the relation of the teeth to the jaws, the jaws to the skull, and the relation of the soft tissues to the teeth and jaws.
A specialised X-ray machine is used to produce the images. During an OPG examination, part of the equipment will rotate around the patient’s head while they remain in a still, standing or sitting position.
OPGs are commonly used during a general dental check up, but can also be conducted to monitor and diagnose:
Cephalograms can help predict mandibular growth in children by allowing accurate orthodontic measurements to be made and can help determine the changes that have occurred with treatment.
These examination use low dose x-rays, a form of radiation, to produce the required images. For dental x-rays, the dose is equivalent to about one day of background radiation.
Dental X-rays are quick, painless and expose the patient to a minimal amount of low-level radiation, whilst providing invaluable information to referrers.
There are no special requirements before a dental x-ray.
You should tell the Radiographer if you are pregnant or if you think you may be pregnant as there is a small risk that the radiation from an X-ray can harm a foetus.
Your doctor or specialist may ask you to bring any previous x-ray images or scans you have, as they can be used for comparison.
You can wear your normal clothes, but you will need to remove any jewellery, eyewear or other metallic accessories or implants around your upper body as these will show up on X-rays and may obscure important structures.
Dental X-rays typically take less than 10 minutes to complete.
There is no recovery time. Patients will be able to return to normal activities and work immediately after the procedure.
