12. 1. Caries

13. 2. Discolored teeth

14. 3. Congenetically malformed teeth

15. 4. Fractured teeth

16. 5. Diastema closure

18. 7. Old restoration replacement or repair

21. Dental restorations or fillings are used to restore function and integrity to the structure of teeth

22. 1. Direct restoration 2. Indirect restoration

23. Direct restorations are performed by placing the restorative material directly into tooth cavity Examples: amalgam, glass ionomers, resin ionomers & composite fillings

24. Indirect restorations involve materials that have been fabricated outside the mouth Examples include: inlays, onlays, veneers, crowns and bridges

25. An intracoronal restoration prepared outside the mouth and luted into the cavity

26. An extension of an inlay that covers some, but not the entire, occlusal surface of the tooth

29. Development of materials and operative techniques to bond restorative materials completely to tissues of teeth

30. 1. Reduce the necessity for extensive tooth preparation

31. 2. Strengthen the remaining tooth structure

32. 3. Less microleakage & less recurrent caries

33. 4. increased retention of restoration
