How do you tell the difference between maxillary and mandibular X-rays?

Maxillary X-rays

-Taken with the patient's head tilted back and the X-ray beam directed horizontally.

-Shows the upper teeth, including the molars.

-Can also show the sinuses and the base of the skull.

Mandibular X-rays

-Taken with the patient's head tilted forward and the X-ray beam directed vertically.

-Shows the lower teeth, including the molars.

-Can also show the mandible (lower jaw) and the temporomandibular joint (TMJ).

Here are some other ways to tell the difference between maxillary and mandibular X-rays:

- Maxillary X-rays are usually taken with the patient's mouth open, while mandibular X-rays are usually taken with the patient's mouth closed.

- Maxillary X-rays show more of the upper teeth, while mandibular X-rays show more of the lower teeth.

- Maxillary X-rays can also show the sinuses, while mandibular X-rays can show the mandible and TMJ.

If you are not sure if an X-ray is a maxillary or mandibular X-ray, you can always ask your dentist or the dental assistant.
