  3. 3. What is Dental Caries? • Definition. • Destructive process. • What could happen if it is not treated? • pain, infection… • How does it look like? • Small chalky area –>large brown cavitation.
  4. 4. Causes Carbohydrates Tooth surface Bacteria Time
  5. 5. Mechanism Metabolism Acid Drop in pH Demineralization Cavitation
  6. 6. Classification Dental Caries Location Rate of Progression Black Pit & Fissure Caries Smooth Surface Caries Acute Incipient Chronic Recurrent Caries Class I Class II Class VI Class III Class IV Class V
  7. 7. Pit & Fissure Caries • What are pits and fissures? – Anatomical landmark on a tooth. • What is the pattern of the decay? – Two triangles with conjoined bases.
  8. 8. Smooth-Surface Caries Three types of smooth-surface caries: I. Proximal (inter-proximal) caries. II. Root caries. III. The third type. This radiograph shows proximal caries.
  9. 9. Rate of Progression • Acute. (fast with pain) • Chronic. (slow without pain) • Recurrent caries. (with previous history) • Incipient. (without previous history)
  10. 10. Black Classification System Black classification is based on the required treatment. • Class I. (occlusal). • Class II. (posterior proximal). • Class III. (anterior proximal). • Class IV. (incisal). • Class V. (cervical). • Class VI. (caries in cusps)

  13. 13. Diagnosis • The primary diagnosis. – Light, dental mirror & explorer. • Dental radiographs.
  14. 14. Treatment • Small caries. (reminerlize lost structure) • Large caries. (prevent further destruction) Trays used for applying fluoride
  15. 15. Treatment • Dental filling • Crowns • RCT • Extraction
  16. 16. Conclusion • Dental caries is considered as one of the diseases of the human body which should be treated. ! • Frequent dental visit for routine dental check up help prevent dental caries.
