Enamel rods extend perpendicular to the dentoenamel junction,but curve slightly toward the cusp tip.

Question

Quizplus · Accepted Answer

Enamel rods, also known as enamel prisms, extend from the dentoenamel junction towards the outer surface of the tooth. While they generally extend perpendicular to the dentoenamel junction, they do curve slightly as they approach the cusp tips, following the overall shape of the tooth. This curvature helps in distributing masticatory forces and contributes to the enamel's strength.
