  • Periapicals (not p.a.’s)

  • Max/mand occlusals

  • Extraoral/lateral film

  • Soft tissue x-ray

  • Panoramic radiographs

Extra oral film l.jpg

Extra Oral film

  • Lateral Film

Trauma l.jpg


  • Soft tissue Film

  • Indicated after trauma to locate missing piece(s) of fractured tooth.

Panaramic radiograph l.jpg

Radiographic diagnosis of dental anomalies l.jpg

Radiographic diagnosis of dental anomalies

  • Ankylosis

Anomalies l.jpg


  • Gemination : unsuccessful attempt of an individual tooth bud to divide into two.

Anomalies18 l.jpg


  • Dilaceration

Anomalies19 l.jpg


  • Peg lateral

  • Supernumary primary lateral

Anomalies20 l.jpg


  • Fusion: dentinal union of two teeth.

  • Supernumary tooth

  • Missing lateral

Anomalies21 l.jpg


  • Concrescence: fusion with a cemental union.

Anomalies22 l.jpg


  • Amelogenesis Imperfecta

  • Thin enamel

  • Increased dentin

Anomalies23 l.jpg


  • Unfavorable resorptive pattern of roots.

Pathology l.jpg


  • Retained primary root tips.

Pathology25 l.jpg


  • Furcation involvement

Pathology26 l.jpg


  • Furcation involvement with internal root resorption.

Pathology27 l.jpg


  • Internal resorption with furcation involvement.

Artifacts optical illusions l.jpg

Artifacts/optical illusions

  • Cervical burnout

  • Mach band phenomenon

  • It may take 30%-70% demineralisation to occur before it can be evidenced radiographically.

  • Radiographs are 2D views of 3D objects.
