What type of tissue is gingiva?
The gingiva is part of the masticatory mucosa that provides an internal defense mechanism against pathogens and mechanical stress. It is composed of a dense, vascular fibrous tissue with a keratinized stratified squamous epithelium.
What are 5 tissues of the Periodontium?
Periodontium is composed of the gingiva, periodontal ligament, cementum, and alveolar bone. Periodontitis is active inflammation of the periodontium.
How do you describe gingival tissue?
Healthy gingiva is described as ‘salmon’ or ‘coral pink’. It may be pigmented, which reflects the ethnic origin of the subject. The gingiva is firm in consistency and firmly attached to the underlying alveolar bone. The surface of gingiva is keratinised and may exhibit an orange peel appearance, called ‘stippling’.
What two tissues make up the gingiva?
The gingiva is composed of an outer epithelium and an inner network of connective tissue. This outer epithelial layer is keratinized, forming a protective layer around the tooth.
How many types of gingiva are there?
Structure of the Gingiva There are two types of gingiva and several important anatomic regions. Alveolar mucosa – The area of tissue beyond the mucogingival junction. It seems less firmly attached and redder than the attached gingiva.
What type of connective tissue is alveolar mucosa?
It comprises stratified squamous epithelium, termed “oral epithelium”, and an underlying connective tissue termed lamina propria.
What are the 4 components of the periodontium?
The periodontium is a connective tissue consisting of four components: cementum, the periodontal ligament (PDL), alveolar bone, and gingival tissue.
Where is periodontium located?
The periodontium is the specialized tissues that both surround and support the teeth, maintaining them in the maxillary and mandibular bones. The word comes from the Greek terms περί peri-, meaning “around” and -odont, meaning “tooth”. Literally taken, it means that which is “around the tooth”.
Is gingiva connective tissue?
Gingival fibers are the connective tissue fibers which are found in the gingival tissue adjacent to the teeth. They aid in holding the gum tissue firmly against the teeth. They are primarily composed of type I collagen, however, type III fibers are also involved.
What are gums made of?
Most modern gums are based on a synthetic equivalent, a rubbery material called polyisobutylene that’s also used in the manufacture of inner tubes. Polyisobutylene is mixed with plasticisers and materials – all food grade – to make the gum mixture chewable.
Where is the alveolar mucosa located?
Alveolar mucosa is the soft, thin mucous membrane that sits above the marginal gingiva and the attached gingiva, and continues across the floor of the mouth, cheeks, and lips. It is bright red in color due to being rich with blood vessels, and is shiny and smooth in appearance.
What are the causes of gingival hyperplasia?
Inflammatory gum enlargement Gingival hyperplasia can occur as a direct result of inflammation.
What is unattached gingiva?
Unattached Gingiva. \\The portion of gingiva that extends from the gingival crest to the crest of the bone is called unattached gingiva. It can also be called the free gingiva. It can be displaced and is not bound directly to the tooth or bone.
Is attached gingiva keratinized?
Keratinized attached gingiva protects the tissue around teeth and implants from trauma. The tight contact of the keratinized attached gingiva which is from the gingival margin to the nonkeratinized free gingival margin is essential for implant health and maintenance.2.
What is keratinized gingival?
The keratinized gingival is the part of the oral mucosa which covers the gingiva and hard palate. It extends from the free gingival margin to the mucogingival junction and consists of the free gingiva as well as the attached gingiva. The width of keratinized gingiva is an important factor when it comes to dental implants.
