  1. Unit 6 Radiographic Interpretation of Dental Caries

  2. Severity of Caries • Early, incipient (1st degree) • Moderate (2nd degree) • Advanced (3rd degree) • Extensive (4th degree)

  10. Proximal Caries

  11. Cemental Caries

  12. Recurrent Caries • Caries immediately next to a restoration • Inadequate margins or excavation • Pulpal necrosis • Metallic restorations often hide • Clinical examination

  13. Recurrent Caries

  17. Occlusal Caries

  18. Adumbration

  19. Adumbration • Between CEJ and alveolar crest • Diffuse radiolucency • Ill-defined borders • Presence of the edge of root • Clinical evaluation

  20. Adumbration

  21. Rampant Caries • Children • Poor dietary habits • Extensive caries • Proximal and smooth surface • Socio-economic factors
