Description:
Canine tooth in osseous alveolus.

Keywords/Mesh: oral cavity, mouth, tooth, enamel, dentin, pulp canal, apical foramen, acellular cement, periodontal ligament, alveolar bone, histology, POJA collection

​3.6  POJA-L123

Title: Apex of the tooth in osseus socket (alveolus) (longitudinal section)

Description:
Stain hematoxylin-eosin, human adult. From top to bottom: 

• Apex region with two tips of dentin covered with cement (darker stained rim) (left and right side); note at right tip a dark calcified spot (free cementicle).
• Centrally pulp canal between the tips filled with connective tissue containing blood vessels and a thick bundle of nerves.
• In the middle a wide spaced apical foramen where pulpal connective tissue continues into the periodontal ligament (left and right side).
• Bundles of collagen fibers (apical fibers) present between cellular cementum and the osseous alveolar wall (bottom left and right).

3.6 POJA-L128. Root of tooth within osseous socket (cross-section)

​3.6  POJA-L128

​Title: Root of tooth within osseous socket (cross-section) 

Description:
Stain hematoxylin-eosin, human adult.  From left to right:

• Bundle bone of alveolus.
• Oblique fibers of periodontal ligament with blood vessels (broad layer of light-stained connective tissue).
• Flattened cementoblasts  settled on a thin light rim of cementoid.
• Darker stained acellular cementum, the so-called acellular extrinsic fiber cementum as collagen fibres protrude from the periodontal ligament into cementum (Sharpey’s fibers). 
• Incremental  lines without cementocytes.
• Dentinocemental junction as a wavy line.
• Dentin.
