I'm looking into a dental question about preparing a class II cavity on a deciduous molar. The options ask about the proximal walls. My knowledge tells me that for primary teeth, the occlusal enamel rods slope differently than in permanent teeth. In this case, the proximal box walls are typically prepared either perpendicular to the external surface or slightly diverging occlusally. I'll need to finalize which option best fits this understanding for an amalgam restoration.

I’m considering what “converge toward occlusal surface” means. It suggests a narrower box occlusally than cervically, which is typical for retention. Conversely, if it diverges occlusally, it would be wider, like inlays. For amalgam, we converge, and for inlays, we diverge. So, Option B seems correct. However, Option A talks about following enamel rods, which might not be the most specific for retention. I’ll want to dig deeper into textbook references to clarify this.
