- Q1. Which classification system is most commonly used to describe cavity location and design in restorative dentistry?
- Q2. According to G.V. Black’s classification, a cavity located in the pits and fissures of a molar’s occlusal surface is classified as:
- Q3. Which class describes interproximal decay on a premolar (posterior tooth) that involves contact area but not the occlusal surface?
- Q4. A cavity on the mesial surface of a maxillary central incisor, not involving the incisal edge, falls under which class?
- Q5. Decay involving the incisal edge and proximal surface of a maxillary canine should be classified as:
- Q6. Which cavity class refers to lesions on the gingival third of the facial or lingual surfaces of any tooth (anterior or posterior)?
- Q7. Which class was later added to G.V. Black’s original five-class system to account for caries or damage on cusp tips and incisal edges?
- Q8. In cavity design, what is the “outline form” primarily concerned with?
- Q9. What is the purpose of designing appropriate resistance form in a cavity preparation?
- Q10. Which cavity classification describes a lesion located on the buccal pit/fissure of a premolar’s occlusal two-thirds buccal surface?
- Q11. Which classification would be appropriate for a cavity on the distal surface of a first molar and also extending onto its occlusal surface (involving more than…
- Q12. Which of the following is a limitation of the traditional G.V. Black cavity classification when used with modern adhesive restorative materials?
- Q13. What is meant by the “retention form” in cavity preparation design?

- Q15. Decay found on the incisal edge of a worn canine tooth (without other surfaces involved) corresponds to which class?
- Q16. Which design principle ensures that the prepared cavity resists displacement or fracture when the restoration is loaded during chewing?
- Q17. In modern conservative dentistry, what is a criticism of strictly following classical cavity designs derived from Black’s principles?
- Q18. Which classification system (by number of surfaces involved) defines a cavity that affects three or more tooth surfaces?
