Radiograph interpretation

dental caries(pain-,top-,vt-)

Initial caries/white spot lesion/stains

  • Coronal portion shows no abnormality
  • Radicular portion shows no abnormality

Acute dental caries

  • coronal portion shows well-defined radiolucency involving enamel and dentin

  • Radicular portion shows no abnormality

Chronic dental caries

  • Coronal portion shows mesiocornal ill-defined radiolucency involving enamel and dentin

  • Radicular portion shows no abnormality

grossly decayed

  • Coronal portion shows loss of tooth structure involving enamel and dentin

  • Radicular portion shows no abnormality

acute pulpitis

  • coronal portion shows well-defined radiolucency involving enamel, dentin and pulp

  • Radicular portion shows no abnormality

chronic pulpitis

  • Coronal portion shows mesiocornal ill-defined radiolucency involving enamel,dentin and pulp
  • Radicular portion shows no abnormality

rootstumps

  • Coronal protion shows loss of tooth structure involving enamel,dentin and pulp
  • Radicular portion shows no abnormality
