1. CHAPTER 17
Dental Caries

3. Radiologic Examination to Detect Caries

4. EXAMINATION WITH CONVENTIONAL INTRAORAL
FILM

6. 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.

7. Radiographic Detection of Lesions
• PROXIMAL SURFACES
• OCCLUSAL SURFACES
• Typical Radiographic Appearance
• False Interpretations
• Lesions with and Without Clinical Cavitation
• Treatment Considerations

8. Typical Radiographic Appearance

11. False Interpretations :
• pits and fissures
• cervical burnout
• Mach band effect
• dental anomalies, such as
hypoplasticpits and
concavities produced by wear.

12. • In cases where the demineralization is not yet
radiographically visible, failure to detect the
lesion is a false-negative outcome

13. • overlapping contact points in
the radio- graphic image may
obscure a lesion .

14. Lesions with and Without Clinical Cavitation

15. Treatment Considerations

16. OCCLUSAL SURFACES
• Typical Radiographic Appearance
• False Interpretations
• Cavitation and Treatment Considerations

17. Typical Radiographic Appearance

18. False Interpretations

19. RAMPANT CARIES

20. BUCCAL AND LINGUAL SURFACES

21. ROOT SURFACES

22. ASSOCIATED WITH DENTAL RESTORATIONS

24. THERAPY AFTER RADIATION

25. Alternative Diagnostic Tools to Detect Dental Caries
• light fluorescence (QLF)
• Diagnodent laser-light
• fiberoptic transillumination (FOTI)
• electrical conductance measurements (ECM)
• ultrasonography.

26. Treatment Considerations
