What is the function of the attachment tissues of the teeth?
The periodontium is a complex structure composed of the gingiva, periodontal ligament (PDL), cementum, and alveolar bone (Figure 11-1). The primary functions of the periodontium are to allow the tooth to be attached to the bone and to provide a barrier for the underlying structures from the oral microflora.
Why is it important to know the amount of attached gingiva?
Assessment of the width of attached gingiva is vital in assessing the risk of periodontium to be affected by disease. In the assessment of width of gingiva, the mucogingival junction serves as an important anatomical landmark, which can be demarcated by various methods.
What is the function of the gingival sulcus?
The gingival sulcus (or gingival crevice) is that little ridge in your mouth where your teeth meet your gums. Keeping it clean is crucial for gum and tooth health. Good oral hygiene is important — and the more you know about your mouth, the better you can take care of it throughout your life.2021-08-31
Why is gingival sulcus important?
It is important to keep that space clean and it also plays an important role in your oral health, which can help avoid gum issues in the near future. Since it is a space between the tooth and the gums, the gingival sulcus is obviously considered to be a landing spot for plaque.
What are parts of gingiva?
The gingiva is divided into free marginal gingiva and attached gingiva by the free marginal groove (Fig. 1.18). The free gingiva has an undulating contour; the triangular projections between the teeth are called interdental papillae.
Where is the gingival sulcus?
The gingival sulcus is the natural space located between the surface of the tooth and the surrounding gum or gingival tissue.
What is the space between the free gingiva and the tooth called?
As the free gingiva is not attached to the tooth, there is a shallow potential space between the free gingiva and the tooth known as the gingival sulcus (see Fig. 17.1). The depth of the sulcus can be assessed by gently inserting a graduated periodontal probe until resistance is encountered.
What is the free gingival groove?
The free gingival groove is defined as a shallow V-shaped groove. which runs parallel to the margin of the gingiva at a distance of 0.5-1.5 mm. (Orban 1948). It is thought to develop at the level of, or somewhat apical to. the top of the epithelial attachment due to functional impacts on the free.
What is the difference between gingiva and gum?
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 is the difference between gingival and periodontal?
For patients diagnosed with gingivitis, it is not all doom and gloom. Not all gingivitis progresses to periodontitis. The major difference between the two is that gingivitis is reversible, while periodontitis is not.
What is gingiva and types?
Types of Gingiva. Attached Gingiva: Gingival tissue laying between the alveolar gingiva and the mobile gingiva. The tissue is roughly four to five millimeters wide, depending on location, and tightly affixed to the underlying periosteum of alveolar bone.
Why is the sulcus important?
Gingival sulcus: V-shaped crevice that surrounds each tooth, bounded by tooth on one side and epithelium lining free margin of gingiva on the other. Sulcus is ideal for bacteria; it is resistant to the cleaning action of saliva. Gingival fluid (sulcular fluid) is a rich nutrient source for microorganisms.
What is gingival dental?
Gingiva is another word for the gums, or the soft, pink tissue that surrounds and protects the bottom of the teeth where they enter the jawbone. The gingiva is attached to the tooth, which forms a seal between the mouth and the underlying bone.
What makes up the gingival sulcus?
The gingival sulcus is lined by the sulcular epithelium. Sulcus is Latin for groove. The depth of the sulcus is surrounded by two different entities which include: apically by the gingival fibers of the connective tissue attachment and coronally by the free gingival margin. A healthy depth is three millimeters or less.
What is the function of attached gingiva?
The keratinized attached gingiva provides the periodontium with increased resistance to external injury, contributes to the stabilization of the gingival margin, and aids in dissipating physiological forces exerted by the muscular fibers of the alveolar mucosa on the gingival tissues.
What is gingiva and function?
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.2016-02-01
What is the gingiva?
The tissue of the upper and lower jaws that surrounds the base of the teeth. Also called gums.
What is the sulcus of the tooth?
The gingival sulcus is the natural space located between the surface of the tooth and the surrounding gum or gingival tissue. The gingival sulcus is lined by the sulcular epithelium. Sulcus is Latin for groove.
