Common

Location

Epicenter is within a neurovascular canal (Inferior alveolar canal or nasopalatine canal)

Location

Epicenter is located inferior to the inferior alveolar canal (IAC)

border-cortication

Number

Single : There are no other related lesions present within the jaws.

number-multiple

Multiple : There are other related lesions within the jaws.

number-multiple

Border Definition

Well-defined : The periphery of the lesion is clearly demarcated.

border-cortication-corticated

Ill-defined : The borders of the lesion is not clearly demarcated.

border-cortication-non-corticated

Internal Density

Radiolucent : The density of the lesion is equal to air, fluid or soft tissue

internal-density-radiolucent

Mixed : The lesion contains a mix of radiolucent and radiopaque components

internal-density-mixed

Radiopaque : The density of the lesion is equal to bone.

internal-density-radiopaque

Border Cortication

Corticated : The lesion is demarcated by a well-defined radiopaque line.

border-cortication-corticated

Non-Corticated : There is no radiopaque line demarcating the lesion periphery

border-cortication-non-corticated

Locularity

Unilocular : The lesion does not contain internal septations.

locularity-unilocular

Multilocular : Contains internal septations.

locularity-multilocular

Neither Unilocular nor multilocular : Does not appears to have a surrounding border or internal septations that would allow it to be defined as uni- or multi-locular

locularity-neither1

Encapsulation

There is a radiolucent border surrounding the lesion, representing soft tissue encapsulation or PDL space.

encapsulation-yes

Periapical Association

Lesion is associated with a specific single tooth periapex

Yes : The lesion is clearly associated with a single tooth.

periapical-association-yes

No : The lesion is not clearly associated with any one single tooth.

periapical-assocation-no

Follicular Association

Lesion is in a follicular relationship with an associated tooth

Yes : The lesion is associated with the crown or appears to arise from within the follicular space surrounding the crown.

follicular-association-yes

No : The lesion is not associated with the crown or does not appear to arise from within the follicular space surrounding the crown.

follicular-association-no

Expansion

Demonstrating expansion that is significant relative to lesion size

expansion-yes
