ALIMENTARY SYSTEM
ANATOMY OF THE ENAMEL ORGAN



Introduction

Odontoblasts are cells in the enamel organ which forms the tooth. They secrete dentine.


Properties

Odontoblast Histology - Copywright RVC 2008
  • Derived from mesenchyme
  • Single layer of elongated columnar cells
  • At dental-pulp border
  • Secrete dentine which is a mineralised matrix of collagen I, dentine and proteins
  • Outer layer of the dental papilla
  • The first layer of dentine is formed on the enamel organ. As production increases, the odontoblasts are displaced from the enamel
  • It is a major part of the tooth structure and is produced continually by the odontoblasts.
  • Rate of dentine synthesis is increased during repair as it is innervated (but still acellular).
