[jin-ji´vah, jin´jĭ-vah] (pl. gin´givae) (L.) the part of the oral mucosa covering the tooth-bearing border of the jaw; called also gum. Called also alveolar gingiva. free gingiva the portion that surrounds the tooth and is not directly attached to the tooth surface.
What are the two types of gingiva?
There are two types of gingiva that are clearly recognizable and they are known as the marginal gingiva that is mobile and the attached gingiva.
What are the 3 anatomical division of the gingiva?
Gingiva comprises part of the masticatory oral mucosa that covers alveolar bone surrounding the tooth and is divided in three anatomical areas: marginal gingiva comprises the free edge of gingiva surrounding the tooth and covers the internal walls of gingival sulcus, attached gingiva is firmly bonded to the underlying
What type of connective tissue is alveolar mucosa?
It comprises stratified squamous epithelium, termed “oral epithelium”, and an underlying connective tissue termed lamina propria.
How do you know if your attached gingiva?
Place your probe on the outside of the tissue and measure from the gingival margin to the mucogingival junction. Now measure the sulcus or pocket depth (probing depth). Subtract the probing depth from the outside measurement of the gingiva, and you will have the width of attached gingiva.
What is the normal gingiva?
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 is festooned gingiva?
Exaggerated rolling of the free gingival margin. Usually associated with plaque induced inflammation.
What is the function of gingiva?
The gingiva (or gums) is the tissue that surrounds and protects the teeth and underlying bone. The gingiva is attached to the tooth, forming a seal that protects the underlying bone and helps provide a barrier against infection.
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.
Why gingiva is firm and resilient?
39. Consistency: The gingiva is firm & resilient with exception of the movable free margin, tightly bound to underlying bone. The collagenous nature of lamina propria & its contiguity with mucoperiosteum of alveolar bone determines the firmness of attached gingiva. Resilient is due to gingival fibers.
What is difference between gum and gingiva?
Gum, also called gingiva, plural gingivae, in anatomy, connective tissue covered with mucous membrane, attached to and surrounding the necks of the teeth and adjacent alveolar bone. Before the erupting teeth enter the mouth cavity, gum pads develop; these are slight elevations of the overlying oral mucous membrane.
What are the three types of oral mucosa?
Histologically, the oral mucosa is classified into three categories, lining, masticatory, and specialized. The epithelium of the lining mucosa is nonkeratinized stratified squamous, whereas that of the masticatory mucosa is ortho- or parakeratinized, to protect it from the shearing forces of mastication.
What is an example of lining mucosa?
Lining mucosa includes the buccal mucosa, labial mucosa, alveolar mucosa, as well as the mucosa lining the ventral surface of the tongue, floor of the mouth, and soft palate.
What tissue is lining the oral cavity?
oral mucosa The mucous membrane that lines the structures within the oral cavity limits is known as oral mucosa. This is a wet soft tissue membrane that extends from the junction between the vermilion border of the lips and labial mucosa anteriorly to the palatopharyngeal folds posteriorly.
What is the importance of alveolar process?
In addition to connecting your teeth to your jawbone, your alveolar process is vital to your teeth’s arrangement and the function of your periodontal ligament (PDL). The alveolar process is uniquely able to withstand the forces put on your mouth by chewing due to its unique composition.
Why is attached gingiva important?
Historically, the presence of a wide zone of attached gingiva has been considered beneficial, as the gingiva plays an important role in maintaining the periodontium in health. It provides a physical barrier to oral biofilm, dissipates masticatory forces and protects the periodontium from injury.
How is gingiva attached to supporting structures?
The gingiva ends at the cervix of each tooth, surrounds it and attaches to it by a ring of specialised epithelial tissue — the junctional epithelium. This epithelial attachment provides continuity of the epithelial lining of the oral cavity with the surface of the teeth.
Is the space between the tooth and the free gingiva?
The gingival sulcus is an area of potential space between a tooth and the surrounding gingival tissue and is lined by sulcular epithelium. The depth of the sulcus (Latin for groove) is bounded by two entities: apically by the gingival fibers of the connective tissue attachment and coronally by the free gingival margin.
How do I know what size my gingiva is?
Where is attached gingiva located?
alveolar bone The gingiva surrounds the teeth and the marginal parts of the alveolar bone, forming a cuff around each tooth. It can be divided into the free gingiva, which is closely adapted to the tooth surface, and the attached gingiva, which is firmly attached to the underlying periosteum of the alveolar bone (Figs 4.3, 4.4).
What is the free gingiva?
The free gingival margin is the area located between the sulcular epithelium and the epithelium of the oral cavity. This interface exists at the most coronal point of the gingiva, which is also known as the crest of the marginal gingiva.
Why stippling is absent in marginal gingiva?
Stippling is usually seen in attached gingiva as it is firmly attached to the underlying cementum and alveolar bone with the help of collagen fibers of the connective tissue. Stippling is lost as age progress, in most adult patients above 50 years there is no stippling of Gingiva.
What means festooned?
1 : a decorative chain or strip hanging between two points walls decorated with festoons of flowers. 2 : a carved, molded, or painted ornament representing a decorative chain Around the mirror were carved festoons of grapevines. festoon. verb. festooned; festooning; festoons.
What is fibrotic gingiva?
Fibrotic gingiva is described as “hyperkeratinized [tissue] with an abnormal whitish thickening of the keratin layer of the epithelium.”1 The problem is that, at first glance, it appears light in color and “firm” to the touch. In reality, it appears light because of the lack of blood flow and constricted blood vessels.
What nerve supplies the gingiva?
The innervation of the oral gingiva is unique because all the nerves supplying the gingival mucosa originate from the mandibular and maxillary branches of the trigeminal nerve (CN V).
What is gingiva?
(JIN-jih-vuh) The tissue of the upper and lower jaws that surrounds the base of the teeth. Also called gums.
What is the neck of the tooth called?
Neck. The neck, also called the dental cervix, sits between the crown and root. It forms the line where the cementum (that covers the root) meets the enamel.
What does gum infection look like?
A person with gum disease will typically have one or more of the following signs and symptoms: Bright red, swollen gums that bleed very easily, even during brushing or flossing. A bad taste or persistent mouth odor. White spots or plaques on the gums.
What are the 4 stages of periodontal disease?
Periodontal disease is broken up into four separate stages: gingivitis, slight periodontal disease, moderate periodontal disease, and advanced periodontal disease.
Can gums grow back?
Once the gums have receded, they cannot grow back. However, some treatments can reattach and restore gum tissue around the teeth. Maintaining good oral hygiene and attending regular dental checkups can help prevent, slow, or stop gum recession.
How do you determine the surface texture of gingiva?
The surface of the gingiva, or gums, commonly has a texture that is referred to as being stippled or resembling that of an orange peel. Only present on the attached gingiva connected to the alveolar bone, stippling does not present on the freely moveable alveolar mucosa.
What causes stippling in gingiva?
Stippling occurs as a result of the microscopic elevations and depressions of the surface of the gingival tissue due to the connective tissue projections within the tissue. The degree of keratinization and the prominence of stippling appear to be connected.
What is recession in dentistry?
When your gums recede or pull away from your teeth, it is called gum recession. Gum recession can happen to people of all ages. Sometimes it happens even if a person takes good care of his or her teeth. Gum recession can cause problems for your dental health.
