Special considerations are described for pediatric and atrophic mandibles.
Which physical findings are characteristic of a mandibular fracture?

What is the purpose of a radiograph of the mandible?
A properly positioned radiograph demonstrates the lower dental arch and floor of the mouth. The entire mandibular body and lower teeth should be visualized.
