Question

question 42
what is the term for the four sections of the divided dental arches?
maxillary
mandibular
sextant
quadrant

Explanation:

To solve this, we analyze each option:

• "maxillary" refers to the upper jaw, not the sections of dental arches.
• "mandibular" refers to the lower jaw, not the sections.
• "sextant" divides the dental arches into six sections, not four.
• "quadrant" means a quarter or four sections, which matches the description of the four sections of divided dental arches.
