  1. DENTAL CARIES&PERIODENTAL DISEASES DR SAMY I ALAGHA A PROFESSOR&CONSULTANT OF RADIOLOGY

  2. DENTAL CARIES

  3. RADIOGRAPHIC EXAMINATION OF DENTAL CARIES • BITEWINGS • PERIAPICALS (PARALLELING TECHNIQUE) • PANORAMA

  4. ABNORMAL SHADOWS SIMULATING DENTAL CARIES 1-Cervical burnout Well defined radiolucent shadow at neck of teeth caused by: a-Anatomical configuration of the teeth b-Variable X-ray penetration of crown,neck&root. It is obvious in increased exposure fs&large metalic restoration

  5. D.D OF DENTAL CARIES • 1-LOCATION • 2-TRIANGULAR • 3-USUALLY AFFECT PREMOLAR

  6. ABNORMAL SHADOWS SIMULATING DENTAL CARIES 2-PERITUBULAR DENTINE This occur after caries and its restoration>>>peritubular dentin in tubules under the restoration>>>normal dentin appear more radiolucent

  7. CLASSIFICATION OF DENTAL CARIES 1-OCCLUSAL CARIES :( in posterior teeth) • Incipient lesions • Moderate lesions>>radiolucent zone in dentine • Severe lesions>>> radiolucent hole in dentine

  8. ENAMEL CARIES

  9. INCIPIENT ENAMEL LESIONS

  10. DENTINAL PROXIMAL LESIONS

  11. OCCLUSAL CARIES IN DENTIN

  12. DENTAL CARIES 2-INTERPROXIMAL CARIES:(Between contact point &free gingival margin) a-Incipient>>>radiolucent notch b-Moderate>>>triangular radiolucency which has broad base at the surface c-Advanced>>>triangle in dentin with base at DEJ D-Severe>>invade more than half of dentine

  13. DENTAL CARIES ROOT SURFACE CARIES: • Age>>>30-60ys • Site>>>Mandibular molars &premolars • Appear as ill defined radiolucency

  14. RAMPANT CARIES

  15. ROOT SURFACE(CEMENTUM)CARIES

  16. RECURRENT CARIES AFTER RESTORATION

  17. RESTORSTIVE MATERIAL RESEMBLING CARIES

  18. RADIATION CARIES

  19. NORMAL ANATOMY OF ALVEOLAR CREST

  20. PERIODENTAL DISEASE

  21. SEVERE PERIODENTAL DISEASE

  22. PERIODENTAL ABSCESS

  23. JUVENILE PERIODENTITIS

  24. END
