[2025-10-01T21:12:40.389805] [PI reasoning] **Exploring access cavity shapes**

I’m looking into the access cavity shape for the mandibular first molar. Generally, the outlines are rectangular or trapezoidal, but there’s some debate about whether they’re trapezoidal or triangular. The mandibular first molar has five pulp horns, and its classic shape tends to be trapezoidal or rhomboidal to accommodate mesial and distal canals. Unlike maxillary molars, which might have a triangular outline, I’ll quickly confirm the shape to ensure accuracy.
