The Orthopantomogram (OPG), also known as a panoramic radiograph, is a dental X-ray that captures a comprehensive view of your mouth, teeth, and jaw in a single image. This includes both upper and lower jaws, the temporomandibular joints (TMJ), and all your teeth. This guide will elaborate on this essential diagnostic tool used by dentists and oral surgeons for various reasons.

An OPG is useful for a variety of purposes, such as evaluating wisdom teeth, identifying dental infections, assessing jaw alignment, diagnosing temporomandibular joint disorders, planning for implant surgery, and much more. The wide view provided by an OPG gives your dental professional a broad perspective on your oral health, which can be critical in diagnosis and treatment planning.
Preparation for an OPG is quite simple and straightforward. Here are some key points to keep in mind:
There's no need for fasting before an OPG. You can eat and drink normally on the day of the test.
Be sure to inform your doctor if you are pregnant or suspect you may be. While the radiation exposure during an OPG is low, it's still crucial to minimize any potential risk to a developing fetus.
On the day of the exam, remove all facial jewelry, including earrings, nose rings, and piercings in the mouth or lips. You'll also be asked to remove dentures, if applicable, before the X-ray is taken.
Allergies are usually not an issue for an OPG. However, inform your doctor if you have had a previous adverse reaction to any type of X-ray contrast material.
During an OPG, you'll be asked to stand or sit in front of the OPG machine with your chin resting on a small ledge to stabilize your head. You'll need to bite down on a sterile mouthpiece to keep your upper and lower teeth apart. The X-ray machine will then rotate around your head to capture images of your mouth and jaw.
You might need an OPG for a variety of reasons, such as evaluating wisdom teeth, identifying dental infections, assessing jaw alignment, diagnosing temporomandibular joint disorders, or planning for implant surgery.
No, an OPG is not painful. You will simply need to hold still while the X-ray machine rotates around your head.
The frequency of OPGs is dependent on your dental condition and the judgment of your dentist. If you are undergoing a specific treatment or have certain dental issues, your dentist might recommend frequent OPGs. Otherwise, an OPG is usually done as part of a routine dental check-up every few years.
The radiation exposure during an OPG is low and is considered safe for most individuals. However, if you are pregnant, make sure to inform your dentist, as any form of radiation can potentially pose risks to a developing fetus.
If your OPG results show any abnormalities, your dentist will discuss the findings with you and suggest further tests or treatment options if necessary.
If your OPG results are abnormal, consult with your dentist. Depending on the findings, you may be referred to a dental specialist such as an oral surgeon, orthodontist, or endodontist.
Orthopantomogram (OPG) is a comprehensive dental X-ray that provides valuable insight into your oral health, informing appropriate diagnosis and treatment strategies. It's an essential tool in modern dentistry that can help to ensure optimal dental care. If you have any further questions about OPG, do not hesitate to ask your dentist or dental healthcare provider.
