Questions and Answers

True denticles are classified based on their relation to the dentin of the tooth. What characterizes attached denticles?

  • They are partly fused with the dentin. (correct)
  • They are entirely surrounded by pulp tissue.
  • They appear as irregular calcific deposits.
  • They are entirely surrounded by dentin.

    • What serves as nidi for false denticles in blood vessels?

  • Collagenous fiber bundles
  • Calcifications
  • Thrombi (correct)
  • Pulp stones

    • How do true denticles initially form?

  • By incremental growth on their surface (correct)
  • As irregular calcific deposits
  • Following collagenous fiber bundles
