3.6  POJA-L156 

Title: Permanent tooth (labiolingual section) 

Description:
Canine tooth in osseous alveolus , stain hematoxylin-scarlet red, human.  From top to bottom: 

• Crown region with dentin but without enamel (decalcified specimens).
• Neck region at the attachment of the gingiva to dentin (left and right).
• Cementum is visible as a dark small rim from the neck region to the bottom of the tooth.
• Periodontal ligament fills the clear gap between cementum and  tooth socket.
• Root region as the main part of the tooth; the bony collar from neck region down to apex is the region of the alveolar process.
• The alveolar bone proper surrounds the root and attachs to the periodontal ligament and is composed of thin bony lamellae (woven bone or bundle bone).
• Supporting alveolar bone (mandible) surrounds above-mentioned lamellae and gives support to the socket. This supporting bone consists of cortical plates (compact bone) and spongy bones. 
• Pulp canal and apical foramen are absent.
