3. Class I All pit and fissures Occlusal surfaces of premolars and molars
Occlusal 2/3 of the facial and lingual surfaces of molars
Lingual surfaces of maxillary incisors

4. Class II
Preparations involving the proximal surfaces of posterior teeth

5. Class III
Preparations involving the proximal surfaces of anterior teeth that do not include angle

6. Class IV
Preparations involving the proximal surfaces of anterior teeth that include the incisal edge

7. Class V
Preparations on gingival third of the facial or lingual surfaces of all teeth

8. Class VI
Preparations on the incisal edges of anterior teeth or occlusal cusp tips of posterior teeth

10. Conservative Cavity Preparation

11. Conservative cavity preparation Vs GV black preparation

12. Conservative cavity preparation
G.V. black
preparation
Conservative cavity preparation
Cervical margin located subginigivally
Break proximal contacts allows passage of enamel hatchet
Width allows straight continuity between isthmus and proximal box
Cervical margin extended to break contact & remove caries
Break proximal contact allows passage of explorer tip
Reserve the S curve that join isthmus and proximal box

13. Box Preparation

14. Box only preparation

15. Box preparation
It is limited to proximal surface without the occlusal extension
It gains the retention from the convergent walls and the retentive groves at the internal line angles

16. Tunnel Preparation

17. Tunnel preparation
It is a modified preparation for conserving tooth structure
It allow the preservation of the marginal ridge of proximal cavities

18. Dental Caries
Deep cavity
Indirect pulp
capping
Management of
Deep
caries
Superficial
& moderate cavity
Restorations
