Chapter 7

2. A cell associated with the amniotic membrane during embryonic development, not directly involved in tooth formation
3. Collagen fibers from the periodontal ligament that are embedded into the cementum on one side and the alveolar bone on the other, providing tooth anchorage.
4. Cells responsible for the resorption of cementum, often seen in orthodontic tooth movement or pathological conditions.
7. Incomplete formation or underdevelopment of enamel, resulting in thin or pitted enamel.
8. A general term, not specific enough for matching in this context without further description.
9. Dentin-forming cell, derived from dental papilla mesenchyme.
11. The process of enamel formation by ameloblasts.
13. Microscopic canals found in dentin, extending from the pulp chamber to the dentinoenamel junction, containing odontoblast processes.
14. Embryonic connective tissue, largely derived from ectomesenchyme in the head, that gives rise to dental pulp, dentin, cementum, and alveolar bone
15. The unmineralized organic matrix secreted by odontoblasts, which later mineralizes to become dentin.
18. Enamel-forming cell.
20. Cementum-forming cell, derived from the dental follicle.
22. The innermost germ layer of an embryo, giving rise to the lining of internal organs.

1. The outermost germ layer of an embryo, giving rise to skin, nervous system, and enamel.
5. A general term, often used to describe cementum (acellular cementum) that does not contain cementocytes, but too broad without context
6. Defective mineralization of enamel, where the matrix is formed but not adequately hardened.
10. A band of ectodermal epithelium that invaginates into the underlying mesenchyme to initiate tooth development.
12. The bony socket in the jaw that holds the tooth
16. dysplasia A general term for any disturbance in enamel formation.
17. The middle germ layer of an embryo, giving rise to muscle, bone, connective tissue, and the cardiovascular system (in the head, dental mesenchyme is largely ectomesenchyme, a neural crest derivative)
19. The primitive oral cavity formed by an ectodermal invagination, from which the dental lamina develops.
21. An ectodermal derivative that forms the enamel of the tooth. It dictates the shape of the tooth and induces dentin formation.
