Abstract :
A static bone cavity manifests itself as a radiolucent area in the
vicinity of the mandibular angle. Five cases of static bone cavity are

to 66 years. There were 3 men and 2 women. The cavities were all

radiolucent lesions on orthopantomography. Their diameter ranged from 10
to 17.5mm on CT. They were between 12 and 18mm in diameter on
