EXTRAORAL PANORAMIC ERRORS – SUMMARY
As a dental professional, you already know about the panoramic radiographic errors and you probably have seen many of them at work. StudentRDH dental hygieneexam prep solution is here to give you a summary of the most common panoramic radiographic errors and how to correct them.
We will leave the textbooks and StudentRDH dental assisting exam prep online courses to explain the science of panoramic radiographs. Today, let’s focus on the summary. We all have a busy schedule and we need a quick way to master our “errors” to become the #starDH (who secretly rules the dental office).

Panoramic radiograph allows the clinician to properly diagnose caries, diseases, fractures, TMJ disorders, bone health, and growth patterns. According to research, about 90% of panoramic images were presented with errors while only about 10% were error free. The top 3 errors are as follows:
- Tongue not touching the palate during exposure
- Chin positioned too far forward or back
- No side identification
Here is a summary of the most important panoramic radiographic errors and instructions on how to correct them.

Now, can you answer this question?
1. Which of the following is NOT true about patient positioning for a panoramic exposure?
- The chin should be tilted down slightly
- The patient should bend the back slightly
- The patient should hold onto the handles and lean back
- The mid-sagittal plane should be perpendicular to the floor
Answer: (B). The patient should bend the back slightly
- When taking a panoramic radiographic image, it is important to position the patient so that all the oral structures stay within the focal through.
- The patient should not bend the back. He/she should always be standing straight. Slumping will result in a panoramic error that shows a straight opacity in the middle of the image (Washington Monument).
- The chin should be slightly tilted down (not too far down, as that would result in an exaggerated smile).
- The patient should hold onto the handles, lean back, and have the mid-sagittal plane perpendicular to the floor.
NOTE: errors with radiographs should be reviewed very carefully.
