Operative Dentistry
Restorative principles, caries management, cavity design, matrix systems, and dental materials — structured for OSCE, viva, and board exams.
What examiners focus on
- Cavity classification (Black's) and when to use each
- Step-by-step preparation design — amalgam vs composite
- Material selection rationale and properties
- Matrix band placement and wedging technique
- Deep caries management and pulp protection
- Finishing, polishing, and occlusal adjustment
- How to justify your restorative choice in viva
5 tips for operative exams
- Always state your diagnosis and justify your cavity design before cutting.
- Know the difference between amalgam and composite prep — examiners will ask why you chose one.
- Matrix and wedge steps are OSCE scoring goldmines — practice the sequence out loud.
- For vivas, link material properties to clinical decisions (e.g. "GIC releases fluoride, so I chose it for the cervical lesion").
- In deep caries questions, say clearly how you preserve pulp vitality while still achieving a reliable final seal.
