What are the three functions of the periodontal ligaments?
The periodontium functions include supporting the tooth, protecting it against oral microflora, and making the attachment of the tooth to the bone possible. [1] To understand the function of the periodontium even further, we can look at its components function individually.
What does the periodontal ligament do quizlet?
14- Periodontal ligament. Functions: help tooth withstand the compressive forces during chewing and remain embedded in the alveolar bone; serves as a source of proprioception, or sensory innervation, so the brain can detect the forces being placed on the teeth. You just studied 24 terms!
Which describes a periodontal ligament?
The periodontal ligament, commonly abbreviated as the PDL, is a group of specialized connective tissue fibers that essentially attach a tooth to the alveolar bone within which it sits. It inserts into root cementum one side and onto alveolar bone on the other.
What is the primary location and function of the Interradicular fibers of the periodontal ligament?
Gingival fiber group
| Fiber group | Location of attachment | Function |
|---|---|---|
| Alveolar crest | Cervical root to alveolar crest of alveolar bone proper | Resist vertical and intrusive forces |
| Interradicular | Between roots to alveolar bone proper | Resist vertical and lateral movement |
What are the functions of the periodontal ligaments Chapter 8?
The PDL protects the blood vessels and nerves from injury by mechanical forces. It also attaches the tooth to the bone in the socket, and the absorption of occlusal forces protects the vessels, nerves and bone from injury [62]. A primary role of the ligament is to act as a medium of force transfer during mastication.
How does the periodontal ligament perform demonstrate its supportive function?
Supportive function The PDL plays a central role in withstanding these forces and transferring them to the bone. It has been shown that because the forces during mastication are applied in different directions, both compression and tension areas exist in PDL during a regular loading scheme 306.
Which fibers of the periodontal ligament are most numerous and function to resist intrusive and rotational forces?
3-Oblique group: Run obliquely from cementum to the bone, are most numerous and constitute the main attachment of tooth. The fibers of this group resist the vertical and intrusive forces.
What are the cells of the periodontal ligament?
Periodontal ligament (PDL) attaches the tooth to the alveolar bone underneath it, and is mainly comprised of structurally aligned collagen fibers along with fibroblasts, epithelial cells, osteoblasts, cementoblasts, and mesenchymal stem cells [58].
Which of the following is the primary factor causing periodontal disease?
Plaque is the primary cause of periodontal disease.
Which periodontal ligament fiber group is most important in resisting intrusive masticatory forces?
In particular, the oblique PDL group, which spatially constitutes approximately 70% of the complex, mainly resists vertical and intrusive forces during mastication applications, while other typical PDL groups generate systemic responses to cope with various types of masticatory forces [9,11].
Whats the definition of periodontal?
: a branch of dentistry that deals with diseases of the supporting and investing structures of the teeth including the gums, cementum, periodontal membranes, and alveolar bone.
