The direction of enamel rods in decidous teeth is_____________?
Correct answer: C. Inclined in an occlusal direction in the cervical third of crown
- A. Same as permanent teeth
- B. Inclined in an apical direction in the cervical third of crown
- C. Inclined in an occlusal direction in the cervical third of crown
- D. None of the above
Explanation
In primary teeth, enamel rods in the cervical third incline occlusally toward the gingival margin, unlike the usual apical inclination described for permanent teeth. This reversal is an important morphological difference in deciduous crowns.
