  2. Restorative objectives for children • Sealing noncarious pits and fissures • Rendering the tooth and the restoration interface caries resistant after tooth repair • Easy handling properties • Cost resonable

  3. Clinical use of GI

  4. Polymerization

  5. Fluoride release

  6. Disadvantage • Lower wear resistance and physical properties compare to composite • Moisture sensitive remain • Unstable color

  7. Classification

  8. Products

  9. Products

  10. SMART & ART

  11. Introduction • SMART=ART • A simplified and modified atraumatic restorative treatment • To remove caries and minimal preparation using only hand instruments and fill it with glass ionomer cement • Without fear

  12. Why SMART? • Slow and gentle technique • More comfortable • No injections or power drills • Field condition • Good alternative in mentally compromised child

  13. Principles • Removing carious tooth tissues using hand instrument only • Restoring the cavity with a restorative material that sticks to the tooth

  14. Cavities suitable • Involving dentin • Accessible to hand instrument • One surface

  15. Contraindications • Pulp disease • Inaccessible to hand instrument

  16. Glass ionomer • Bonds to enamel and dentin • Fluoride release • Easy to use

  17. Update since 2002 • GI best direct application dentin replacement materials • RMGIs • Photopolymerization>> acid/base neutralization reaction • Benefits: • Advantages of GI • Better handling • Greater durability over time • Better physical strength • Wear resistance • Fracture resistance • Fracture toughness

  18. Fuji IX

  19. Instruments • Enamel hatchet to open access • Spoon excavators to ease soft dentin • Plastic instrument to applying the GIC and shaping

  20. Procedures 1. Preparing the cavity 2. Isolation

  21. Procedures 3. Access the cavity by enamel hatchet

  22. Procedures 4. Remove soft caries by spoon excavator

  23. Procedures 5. Cleaning the cavity by dentine conditioner 10-15 s 6. Dry with cotton wool 7. GIC inserted

  24. Procedures 8. Carving

  25. Done!!!

  26. Thank you
