Question

Curved CEJs are expected on:

A) Primary dentition only
B) Permanent dentition only
C) Both primary and permanent dentition
D) Neither primary nor permanent dentition

Answer 1

Curved CEJs are expected on both primary and permanent dentition.

Step-by-step explanation:

Curved CEJs are expected on both primary and permanent dentition. The CEJ, or cementoenamel junction, is the point where the enamel of the tooth meets the cementum of the root. In both primary and permanent dentition, the CEJ can have a slight curve, which is considered normal anatomy.
