What is the function of primary dentin in developing teeth?

1. It acts as a protective layer

2. It supports the dental pulp

3. It forms until the tooth erupts

4. It ensures proper alignment of teeth

The correct answer is: It forms until the tooth erupts

The function of primary dentin in developing teeth focuses on its role in the formation process until the tooth erupts. Primary dentin is the first type of dentin formed during tooth development. It is secreted by odontoblasts and continues to form until the tooth has fully erupted and is in functional occlusion. This layer of dentin is crucial because it provides the necessary structural integrity for the tooth, as well as creating the shape of the tooth prior to eruption. While primary dentin does contribute to the overall health and function of the tooth, its primary significance comes from its developmental role rather than protective or supportive functions. Understanding this aspect of primary dentin is essential in dental terminologies and concepts related to tooth formation and eruption.
