Radiation is used in X-rays to create images of bones and other internal organs.
A X-ray of the upper and lower jaws, including the teeth, is called an OPG.
During the scan, the OPG unit is designed to rotate around the patient's head. An OPG will take about 20 seconds.
An OPG can detect:

• Fractures
• Dislocated jaw
• Infection
• Dentition (teeth)

It can also be used to plan surgical procedures.

The Advantages of an OPG

Painless, quick, and simple Preparation.
There is no special preparation required.

Precautions

Leave all valuables and jewellery at home. Metal objects may be requested to be removed. It is critical to inform your doctor prior to the OPG.If you are or suspect of pregnancy.

Cephalogram Lateral

The lateral cephalogram is another useful assessment tool in dental imaging. This is an x-ray that produces a side view of the head that can reveal important details about the teeth and jaw.
The lateral cephalogram depicts the structure of the face, bone, and soft tissue. These images can be used by your radiologist or dentist to study the relationship of your teeth to your jaw, assess problems with alignment or growth patterns, and plan treatment.
The best tool for determining jaw alignment is the lateral cephalogram. If you have an overbite or underbite, for example, these images will provide more detail and allow your practitioner to develop the best approach for your needs.
In children, this x-ray is commonly used to predict tooth and jaw growth patterns. Adults can also use the lateral cephalogram to study changes caused by treatment or to track other issues.
If you work with an orthodontist, you may be given a lateral cephalogram in addition to the OPG. This x-ray is helpful in tracking treatment progress
