Presentation Transcript


“Radiographic Assessment of the Pediatric Patient”

S.Lal, DDS


Special considerations

  • Risk assessment

  • Evidence of caries/hx

  • Trauma

  • Anomalies

  • Fluoride status

  • Diet


AAPD guidelines for radiographs

  • Based on Age and risk assessment


Child preparation and management

  • Euphemisms

  • Role models

  • Contour film

  • Gag reflex – distraction

  • Parental help

  • Bad taste


Film Sizes

  • Sizes 0,1,2, occlusal/lateral


Radiographic Tools

  • Snap-a-ray

  • Bite wings, periapicals


Radiographic techniques

  • Bite wings

  • Periapicals (not p.a.’s)

  • Max/mand occlusals

  • Extraoral/lateral film

  • Soft tissue x-ray

  • Panoramic radiographs


Bite Tabs


Bite wing x-ray

  • Mesial surface of canine to distal surface of 1st permanent molar


Bite wing x-ray

  • Incipient carious lesion.

  • Overlapping – common error


Occlusal Radiographs


Occlusal Radiographs

  • Posterior max. occlusal radiograph


Extra Oral film

  • Lateral Film


Trauma

  • Soft tissue Film

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


Panaramic radiograph


Radiographic diagnosis of dental anomalies

  • Ankylosis


Anomalies

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


Anomalies

  • Dilaceration


Anomalies

  • Peg lateral

  • Supernumary primary lateral


Anomalies

  • Fusion: dentinal union of two teeth.

  • Supernumary tooth

  • Missing lateral


Anomalies

  • Concrescence: fusion with a cemental union.


Anomalies

  • Amelogenesis Imperfecta

  • Thin enamel

  • Increased dentin


Anomalies

  • Unfavorable resorptive pattern of roots.


Pathology

  • Retained primary root tips.


Pathology

  • Furcation involvement


Pathology

  • Furcation involvement with internal root resorption.


Pathology

  • Internal resorption with furcation involvement.


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.
