Transcript of "Pulp"

  1. 1. Pulp
  2. 2. Pulp• The pulp cavity occupies the central area of the tooth enclosed by dentin.• The pulp has the cellular, fibrous, neural and vascular components of typical loose connective tissue.• The main function of the pulp is the production and maintenance of the dentin. A, Pulp cavity; B, Dentin; C, Odontoblasts
  3. 3. Nerve Plexus of Raschkow• Sensory nerve fibers that originate from inferior and superior alveolar nerves innervate the odontoblastic layer of the pulp cavity.• These nerves enter the tooth through the apical foramen as myelinated nerve bundles.• They branch to form the subodontoblastic nerve plexus of Raschkow which is separated from the odontoblasts by a cell-free zone of Weil.• In addition to the sensory nerves, sympathetic nerve bundles also enter the tooth to innervate blood vessels. A, Odontoblasts; B, Cell-free zone of Weil; C, Nerve plexus of Raschkow
  4. 4. Vascular supply of pulp cavity• The pulp cavity receives blood from one arterial that enters the apical foramen and courses directly to the coronal pulp.• Within the coronal pulp numerous arterial branches form a interconnected network of blood vessels as seen here following filling with ink.• The smallest capillary loops are in the subodontoblastic zone (arrow).
  5. 5. Structures within the pulp cavity• Arterioles, small nerve bundles and fibroblasts are found in the pulp cavity A, Nerve bundle; B, Arteriole; C, Fibroblasts
  6. 6. Structures within the pulp cavity• Arterioles can be distinguished from venules within the pulp cavity by the thickness and contours of their vascular walls. A, Arteriole; B, Venule; C, Nerve bundle (cut in cross-section)
  7. 7. Subodontoblastic region• Below the odontoblastic layer is the cell-free zone of Weil followed by a cell-rich zone which is thought to provide replacement cells for odontoblasts that die.• Within these zones are the nerve plexus of A, Cell-rich zone; Raschkow and capillary B, Cell-free zone; C, Odontoblastic layer; network. D, Dentin
  8. 8. Denticle• The formation of a true pulp stone or denticle is brought about by the differentiation of pulp cells to odontoblasts within the pulp cavity.• The resulting body has an appearance characteristics of dentin with tubules radiating out from the center and predentin A, True pulp stone; around the periphery. B, Pulp cavity; C, Dentin
  9. 9. False pulp stone• The formation of a false pulp stone is caused by the nonspecific calcification of tissue around a central nucleus within the pulp cavity.• This pulp stone is characterized by concentric layers of mineralization rather than radiating tubules as seen in true pulp stones. A, False pulp stone; B, Pulp cavity
  10. 10. Regions of the pulp cavity• The pulp cavity can be divided into two main regions: the coronal pulp is located within the crown of the tooth and the radicular pulp is located within the root. A, Coronal pulp; B, Radicular pulp
