What is the first dentin type formed?

• secondary dentin

• tertiary dentin

• mantle dentin

• circumpulpal dentin

What is the role of dentinal tubules?

• nutrient transport and signals sensory

• provide structural support

• store minerals

• enamel production

Which dentin is closest to the pulp?

What distinguishes mantle dentin from circumpulpal dentin?

what is the significance of the "scalloped" pattern observed at the DEJ?

• indicates areas of incomplete mineralization

• provides mechanical interlocking between dentin and enamel

• signifies presence of predentin
