Understand the Problem
The question is asking about the characteristics of the shape of the axial wall in a dental preparation. It presents multiple-choice options to identify the correct description of the axial wall's shape.

Answer for screen readers
The axial wall is typically characterized by a convex curvature that follows the external contours of the tooth.
More Information
The convex shape allows the axial wall to follow the natural mesiodistal and incisogingival contours of the tooth, providing better adaptation to the tooth's structure.
Tips
A common mistake is to make the axial wall straight rather than convex, which doesn't follow the natural tooth contour and can affect the fit of a restoration.
