Which term refers to the slanted edge in tooth preparation?

Shoulder
Bevel
Chamfer
Undercut

The correct answer is: Bevel

The term that refers to the slanted edge in tooth preparation is "bevel." In dentistry, beveling is a technique used when preparing a tooth for restoration or prosthetic placement. The bevel is created to provide a smooth transition between the prepared tooth structure and the restoration, enhancing both the fit and the esthetics of the final result. This slanted edge allows the restoration material to blend more seamlessly with the natural tooth, which can improve the strength and durability of the restoration. In contrast, other terms like "shoulder," "chamfer," and "undercut" refer to different preparation designs. A shoulder is a flat edge typically used in the preparation for crowns and can be more perpendicular to the axis of the tooth. Chamfers create a rounded edge that is effective for certain types of restorations but do not specifically refer to the slanted nature of a bevel. Undercuts involve areas of tooth structure that are below the height of the adjacent preparation margins, which do not pertain to slanted edges. Thus, bevel is the term that best captures the concept of a slanted edge in tooth preparation.
