The premolar alveoli are what shape in cross section_____________?
Correct answer: B. Kidney shaped
- A. Rectangular
- B. Kidney shaped
- C. Triangular
- D. Oval
Explanation
Premolar alveoli commonly appear kidney-shaped in cross-section because the socket follows the characteristic contour and developmental depressions of premolar roots. The cross-sectional form therefore differs from the more triangular anterior and rectangular posterior alveoli.
