What is a key characteristic of permanent teeth compared to deciduous teeth?

• A. They are smaller in size
• B. They are typically darker in color
• C. They have larger enamel thickness
• D. They are usually 20 in number

Answer: (B)

The correct answer highlights that permanent teeth are typically darker in color compared to deciduous teeth, also known as baby teeth. This difference occurs due to the mineral content and the density of the enamel in permanent teeth, which often lead to a more opaque and darker appearance. The composition of the enamel in permanent teeth is also denser and thicker, contributing to their overall darker shade. In contrast, deciduous teeth tend to have a lighter, more translucent color, as they are designed for a temporary role in the dental arch. The size differences and the number of teeth in each category also play a role in their characteristics; however, these do not pertain to the coloration aspect discussed.
