Chapter 17

  1. 1. CHAPTER 17 Dental Caries
  2. 2. Radiologic Examination to Detect Caries
  3. 3. EXAMINATION WITH CONVENTIONAL INTRAORAL FILM
  4. 4. EXAMINATION WITH DIGITAL IMAGING (1) solid-state sensors : (charge-coupled device [CCD] and complementary metal oxide semiconductor technology [CMOS]) (2) storage phosphors (PSP plates) : that use a filmlike plate that is processed (scanned) after exposure.
  5. 5. Radiographic Detection of Lesions • PROXIMAL SURFACES • OCCLUSAL SURFACES • Typical Radiographic Appearance • False Interpretations • Lesions with and Without Clinical Cavitation • Treatment Considerations
  6. 6. Typical Radiographic Appearance
  7. 7. False Interpretations : • pits and fissures • cervical burnout • Mach band effect • dental anomalies, such as hypoplasticpits and concavities produced by wear.
  8. 8. • In cases where the demineralization is not yet radiographically visible, failure to detect the lesion is a false-negative outcome
  9. 9. • overlapping contact points in the radio- graphic image may obscure a lesion .
  10. 10. Lesions with and Without Clinical Cavitation
  11. 11. Treatment Considerations
  12. 12. OCCLUSAL SURFACES • Typical Radiographic Appearance • False Interpretations • Cavitation and Treatment Considerations
  13. 13. Typical Radiographic Appearance
  14. 14. False Interpretations
  15. 15. RAMPANT CARIES
  16. 16. BUCCAL AND LINGUAL SURFACES
  17. 17. ROOT SURFACES
  18. 18. ASSOCIATED WITH DENTAL RESTORATIONS
  19. 19. THERAPY AFTER RADIATION
  20. 20. Alternative Diagnostic Tools to Detect Dental Caries • light fluorescence (QLF) • Diagnodent laser-light • fiberoptic transillumination (FOTI) • electrical conductance measurements (ECM) • ultrasonography.
  21. 21. Treatment Considerations
