3. Type of the restorative material

Conservative Dentistry
Answer: 2
Explanation: The outline form of a Class V cavity preparation
is primarily determined by the extent of carious tissue. The goal is to remove
all carious dentin while preserving as much healthy tooth structure as possible.
The outline form must encompass the entire area affected by caries to ensure
that the restoration is effective and durable. Other factors, such as the height
of the gingival crest, type of restorative material, and tooth anatomy, may
influence the preparation but are secondary to the extent of caries.
