1. Purposes of Operative Dentistry
Proper diagnosis is vital for treatment
planning.
DIAGNOSIS:
To prevent any recurrence of the
causative disease and their defect.
PREVENTION:
Preventing further loss of tooth structure
by stabilizing an active disease process.
INTERCEPTION:
Preservation of the vitality and
periodontal support of remaining tooth
structure.
PRESERVATION:
Includes restoring form, function,
phonetics, and esthetics.
RESTORATION:

2. Clinical procedures for Operative Treatment

3. Steps in operative/ restorative procedures
Evaluate the tooth to be restored
Obtain local anesthesia
Determine the type of moisture control to be used during the procedure:
Cotton roll (partial Isolation)
Dental rubber dam (complete isolation)

4. Steps in operative/ restorative procedures
4. Prepare the tooth for the restoration
rotary instruments
hand instruments
5. Determine the type of dental materials
to be used
6. Apply dental material

5. Steps in operative/ restorative procedures
7. Burnish, carve or finish the dental material
8. Check the occlusion of the restoration
9. Finish and polish the restoration

6. 1. Evaluate the tooth to be restored Diagnostic phase
a. Clinical examinations
Percussion, pain
Deep caries
b. Radiographic examinations
- Periapical radiograph
- Bitewing
c. Vitality test

7. a. Clinical examination

8. b. Radiographic examination
Periapical
Bitewing
Bitewing+ periapical
Panoramic radiograph, OPG

9. Radiographic examination
Full mouth intra oral radiographs
Bitewings+ periapicals

10. c. Vitality test Electric pulp tester(EPT):
tests the vitalty of the Pulp by passing low electric current throw the tooth  pain
Compare the reading with the opposing or adjacent normal tooth

11. 2. Obtain local anesthesia
Anesthetic Gel
Gauze
Syringe
Cotton tip
Anesthetic solution= carpule
Needles
Short
Long
local anesthesia kit

12. 2. Obtain local anesthesia
Upper teeth
Infiltration
Lower teeth
Nerve block

13. After local anesthesia
Cardboard needle cap-holding device makes recapping needles safer
Sharping container
Cardboard needle cap-holding device makes recapping needles safer

14. Never leave the patient after local anesthesia

15. 3. Moisture control Cotton rolls Cotton pellets Gauze
Dental rubber dam
Saliva ejector
High-volume oral evacuator tip

16. A. Cotton rolls B. Cotton pellets

17. C. Gauze

19. D. Dental Rubber Kit

20. D. Dental Rubber dam
Rubbere dam over the area to isolate the tooth, keep it clean and free of saliva during the dental procedure

21. E. Saliva ejector

22. F. High-volume oral evacuator tip

23. The difference??

24. Suction tips Saliva ejector High-volume oral evacuator
= low volume suction
High-volume oral evacuator
=high volume suction

25. 4. Prepare the tooth for the restoration
Rotary instruments
Hand instruments

26. Rotary instruments
HIGH SPEED HAND PEICE
LOW SPEED HAND PEICE

28. Burs holder

29. Hand instruments

30. 5. Determine the type of dental materials
a. Amalgam
b. Composite

31. c. Glass ionomer
Contains Fluoride/ Release Fluoride in the Oral cavity.
White /light gray in color.
Bond to the tooth structure.

32. d. If no time, or deep caries you can apply temporary filling

33. 6. Apply the dental material

34. Amalgam Alloy of mercury and one or more other metals. Contents:
Silver
Tin
Copper
Zinc

35. a. Application of amalgam
Amalgam capsules
Amalgamator
Amalgam capsule

36. a. Application of amalgam
Dappen dishr
Dappen dish
Amalgam carrier

37. Application of amalgam
Amalgam condenser
Burnisher
Matrix
Retainer
Wedge

38. APPLICATION OF AMALGAM

39. Composite Resin composites
Bond to the tooth structure by Bonding agent
Superior aesthetic properties and to health concerns about the mercury in dental amalgams
Have found increasing application in the repair and rebuilding of teeth.
Chemical cure or light cure restoration.

40. Composite kit
Shade guide
Acid etchant
Bonding material
Composite

41. Composite Select the shade Dry the tooth Acid etchant Wash Dry Bonding
Light cure
Composite in layers 2mm

42. Application of Composite
Acid itchant
Shade selection, Light cure
Dry the tooth
Light cure

43. Application of Composite

44. 7. Burnish, carve or finish the dental material

45. 8. Check the occlusion of the restoration
Articulating paper
High speed hand piece
Diamond bur
High point removal

46. 9. Finish and polish the restoration
Amalgam
Composite finishing strips

48. Before placement of the restorative material
Base: placed in deep cavities to provide pulp protection and insulation
Cavity liner: protects the pulp from irritation and encourages healing
Bonding agent: retention of the composite

49. Before placement of the restorative material
Cavity base: placed in deep cavities to provide pulp protection and insulation
e.g. Glass ionomer cement
Zink oxide eugenol cement
Cavity liner: protects the pulp from irritation and encourages healing
e.g. Dycal= under amalgam, composite
Varnish= under amalgam ONLY
Bonding agent: retention of the composite

50. Cavity liners Dycal under amalgam or Varnish under Amalgam composite
Varnish under Amalgam Dycal under composite
