Step 3 : Analyze Internal Structure

Step 3 : Analyze Internal Structure :


1.Totally Radiolucent :

( Totally radiolucent internal structure is common in Cysts .)

For example : This is one of the totally radiolucent structure . (more examples)

 

 

2.Totally Radiopaque :

( Totally radiopaque  internal structure is observed in Osteomas .)

For example : Osteoma has totally radiopaque structure . (more examples)

 

 

 

3.Mixed Density :

(The mixed density internal structure is seen as the presence of calcified structures (white) against a radiolucent (black) backdrop . In this type of density , the following sections can be seen : )

  • Abnormal Trabecular Patterns ; like :

Periapical image of a small lesion of fibrous dysplasia between the lateral incisor and cuspid demonstrates a change in bone pattern  . A greater number of trabeculae per unit area are present , and the trabeculae are small and thin and randomly oriented in an orange-peel pattern .(more examples)

 

  • Internal Septation ; like :

A) Periapical image of an Ameloblastoma . the multilocular pattern created by septa (arrows) divides the internal structure into small , soap bubble – like compartments .

B) Axial CT image of an Ameloblastoma has typically curved septa (arrow) .(more examples)

 

  • Dystrophic Calcification ; like :

  • Digital panoramic radiography with image suggesting calcifications in the right submandibular and parotid glands . (more examples)

 

 

 

  • Amorphous Bone ; like :

  • Late maturation phase of Periapical osseous dysplasia showing central amorphous bone (radiopaque) surrounded by a soft tissue margin (arrows) (more examples)

 

 

 

  • Tooth Structure ; like :

  • Thin , radiolucent periphery indicating a soft tissue capsule positioned between the internal radiopaque structure of this Odontoma and the radiopaque outer cortical boundary (arrows) (more examples)
