What is an OPG?
An Orthopantomograph (OPG) is a specialized panoramic X-ray of your teeth, jaws, and surrounding structures. It captures a single image that shows your entire mouth, providing a broad view for accurate diagnosis and treatment planning.
Why Do I Need an OPG?
Your dentist may recommend an OPG to:
- Check wisdom teeth (for impaction or eruption)
- Identify jaw fractures or abnormalities
- Plan for dental procedures (implants, braces, extractions)
- Diagnose infections, cysts, or tumors in the jaw
- Assess TMJ (jaw joint) disorders
Preparation Guidelines
- No special preparation required – eat and drink normally.
- Remove jewelry, glasses, or metal items that can block the X-ray.
- Wear a lead apron to protect your body from radiation.
- Tell your dentist if you're pregnant (X-rays are generally avoided unless absolutely necessary).
What to Expect During the Scan
- Stand or sit in front of the OPG machine.
- Rest your chin on a support to keep your head still.
- The machine rotates around your head for 10-20 seconds.
- You may hear a slight humming noise during the process.
- The scan is fast – it usually takes less than a minute.
Procedure Time
- Total visit time: 5-10 minutes
- Scan duration: 10-20 seconds
- Results: Typically available immediately or sent to your dentist within 24 hours.
Post-Scan Guidelines
- No recovery time needed – you can return to your normal activities.
- Minimal radiation exposure – no side effects expected.
- Your dentist will discuss the findings and suggest the next steps.
Key Advantages of OPG
- Wide, single-image view – better than traditional dental X-rays.
- Quick and painless – no discomfort during the scan.
- Low radiation exposure – safer than multiple small X-rays.
- Helpful in planning complex dental procedures like implants or surgeries.
Regular OPG scans help detect dental and jaw problems early and guide the planning of treatments. If you have difficulty staying still during the scan, inform the technician. OPGs are a fast and effective way to assess your oral health.
