Histo Cementum Flashcards
1
Q
What is the function of cementum?
A
It seals root dentin, attaches periodontal fibers, and helps repair root resorption.
2
Q
Where is cementum located?
A
It covers the root of the tooth, between the dentin and periodontal ligament.
3
Q
What are the types of cementum?
A
- Acellular Cementum – No cells, found in the upper root, mainly for attachment.
- Cellular Cementum – Contains cementocytes, found in lower root, helps with repair.
- Intermediate Cementum – Thin layer between dentin and cementum.
4
Q
How does cementum help with root resorption?
A
It can repair and rebuild damaged areas of the root by depositing new cementum.
5
Q
What are the two main types of cementum?
A
- Intermediate Cementum
- Cellular-Acellular Cementum
6
Q
What are the characteristics of Intermediate Cementum?
A
• Homogeneous (uniform in structure).
• Formed by epithelial root sheath cells.
7
Q
What are the characteristics of Cellular-Acellular Cementum?
A
• Thicker than intermediate cementum.
• Has a bone-like structure.
• Formed by cementoblasts, which originate from fibroblasts.
