Relative radiodensity and internal structure of the lesion

The relative radiolucency or radiopacity of the lesion compared to the surrounding bone.

Site and Size of the lesion

The site and the size of a lesion in relation to the adjacent teeth and anatomic structures provide significant information about the type of the underlying condition.

Shape of the lesion

The shape of the lesion can provide information about the irregularity of growth of a tumor.

Outline of the lesion

Τhe outline of the lesion provides information about the nature of the lesion.

Effects on surrounding bone

Features that should be examined are alterations in the size and distribution of trabeculation, evidence of loss of lamina dura.

Effects on the bony cortex

The type of effects on the bony cortex can provide information about the nature of the lesion.

Effects on adjacent teeth

There may be evidence of: root resorption, displacement, delayed eruption, loss of lamina dura.

Periosteal reactions

The type of periosteal reaction to the lesion can provide information about the nature of the lesion.
