Transcript and Presenter's Notes

Title:


1
Radiographic Assessment of the Pediatric Patient
  • S.Lal, DDS

2
Special considerations
  • Risk assessment
  • Evidence of caries/hx
  • Trauma
  • Anomalies
  • Fluoride status
  • Diet

3
AAPD guidelines for radiographs
  • Based on Age and risk assessment

4
Child preparation and management
  • Euphemisms
  • Role models
  • Contour film
  • Gag reflex distraction
  • Parental help
  • Bad taste

5
Film Sizes
  • Sizes 0,1,2, occlusal/lateral

6
Radiographic Tools
  • Snap-a-ray
  • Bite wings, periapicals

7
Radiographic techniques
  1. Bite wings
  2. Periapicals (not p.a.s)
  3. Max/mand occlusals
  4. Extraoral/lateral film
  5. Soft tissue x-ray
  6. Panoramic radiographs

8
Bite Tabs
9
Bite wing x-ray
  • Mesial surface of canine to distal surface of 1st
    permanent molar

10
Bite wing x-ray
  • Incipient carious lesion.
  • Overlapping common error

11
Occlusal Radiographs
12
Occlusal Radiographs
  • Posterior max. occlusal radiograph

13
Extra Oral film
  • Lateral Film

14
Trauma
  • Soft tissue Film
  • Indicated after trauma to locate missing piece(s)
    of fractured tooth.

15
Panaramic radiograph
16
Radiographic diagnosis of dental anomalies
  • Ankylosis

17
Anomalies
  • Gemination unsuccessful attempt of an
    individual tooth bud to divide into two.

18
Anomalies
  • Dilaceration

19
Anomalies
  • Peg lateral
  • Supernumary primary lateral

20
Anomalies
  • Fusion dentinal union of two teeth.
  • Supernumary tooth
  • Missing lateral

21
Anomalies
  • Concrescence fusion with a cemental union.

22
Anomalies
  • Amelogenesis Imperfecta
  • Thin enamel
  • Increased dentin

23
Anomalies
  • Unfavorable resorptive pattern of roots.

24
Pathology
  • Retained primary root tips.

25
Pathology
  • Furcation involvement

26
Pathology
  • Furcation involvement with internal root
    resorption.

27
Pathology
  • Internal resorption with furcation involvement.

28
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.
