What is the function of periodontal fibers?

The gingival fibers are the connective tissue fibers found in the gingival tissue next to the teeth. They help hold the gum tissue firmly against the teeth. They primarily consist of type I collagen, but type III fibers are also involved. These fibers attach the tooth to the gingival tissue.

What are the principal Fibres of periodontal ligament?

The main principal fiber group is the alveolodental ligament, which consists of five fiber subgroups: alveolar crest, horizontal, oblique, apical, and interradicular on multirooted teeth. Principal fibers other than the alveolodental ligament are the transseptal fibers.

What is the primary location and function of the Interradicular fibers of the periodontal ligament?

The ligament fibre bundles do not all insert into the alveolar bone. Interradicular fibres fan out from cementum to tooth in furcation areas of multi-rooted teeth. Dentogingival fibres are the most numerous and run from the cervical cementum into the lamina propria of the free and attached gingiva.

Which of the following fibers regulate the blood flow of periodontal ligament?

The present results suggest that blood flow in the periodontal ligament of cats is controlled by sympathetic alpha-adrenergic fibers for vasoconstriction and by sensory fibers for vasodilation.

What happens to the fibers of the periodontal ligament?

As the tooth erupts, these fringe fibers merge across the width of the periodontal ligament and make the principal fiber bundles of PDL. These fiber bundles become embedded on one side in cementum and on the other side in alveolar bone and are referred to as Sharpey’s fibers. The orientation of these fibers changes with the eruption of the tooth.

Is the periodontal ligament part of the alveolar bone?

The Periodontium refers to the tissues investing and supporting the teeth, including the cementum, periodontal ligament (PDL), alveolar bone and gingiva. The PDL is a soft, specialized connective tissue that connects the tooth to the alveolar bone.

How does the gingival tissue protect against periodontitis?

These fibers attach the tooth to the gingival tissue. Gingival fibers work to protect against periodontitis and once they are compromised, they cannot be regenerated. When the gingival fibers are destroyed, the gingival sulcus increases in depth.

Where are the gingival fibers located in the teeth?

It is attached by the alveolar crest, horizontal and oblique fibers of the periodontal ligament. The gingival fibers are the connective tissue fibers found in the gingival tissue next to the teeth. They help hold the gum tissue firmly against the teeth.
