What is Dentogingival complex?

Objective: The dentogingival complex (DGC) dimension is the sum of widths of connective tissue attachment, junctional epithelium, and sulcus, adjacent to the tooth.

What is shift of Dentogingival Junction?

The shift of dentogingival junction: The position of the gingiva on the surface of the tooth always change with time, when the tip of the enamel first erupts through the mucous membrane of the oral cavity, the epith. almost cover the whole crown.

Where is the junctional epithelium located?

gingival sulcus
The junctional epithelium (JE) is the epithelium that is located at the base of the gingival sulcus.

What is Gingivolabial sulcus?

1. the groove between the maxillary and mandibular halves of the labial vestibule; 2. in the embryo, the groove formed by the deepening of the labial sulcus; its inner wall becomes incorporated with the alveolar process of the mandible or the maxilla, and its outer wall with the lips and cheeks.

Why is the Dentogingival Complex important?

The dentogingival unit (DGU) is the anatomical complex formed by the gingival membrane, gingival sulcus, junctional epithelium and connective tissue insertion, also known as the ìbiological spaceî. It is very important, and its invasion may cause the collapse and apical migration of the fixation apparatus.

What is fenestration and dehiscence?

Fenestration is the condition, in which the bony coverage of the root surface is lost, and the root surface is only covered by the periosteum and gingiva. In such lesions, marginal bone is intact. When this bone defect spreads toward the marginal bone, it is called dehiscence.[1]

What is a Suprabony pocket?

suprabony pocket (supracrestal pocket) a periodontal pocket in which the bottom is coronal to the underlying bone.

Why is junctional epithelium important?

The junctional epithelium is located at a strategically important interface between the gingival sulcus, populated with bacteria, and the periodontal soft and mineralized connective tissues that need protection from becoming exposed to bacteria and their products.

What is the function of junctional epithelium?

Background and objective: The junctional epithelium provides the front-line defense against periodontal bacterial infection. The migration of neutrophils into the junctional epithelium might represent a protective reaction against bacterial infections.

What is a sulcus in the mouth?

The sulcus is “the point at which the tooth and gums meet,” or the natural space between the surface of the tooth and the surrounding gum tissue (also known as the gingiva).

What is false pocketing?

When gingival hyperplasia occurs, periodontal probing measurements can be taken and create the illusion that periodontal pockets are present. This phenomenon is sometimes called a false pocket or pseudopocket.

What happens if you violate biologic width?

Biologic width violation can lead to bleeding or recession of the gingival tissue; chronic inflammation of the gingival tissue, especially immediately around the restoration; the formation of pockets between the gums and teeth; and loss of alveolar bone.

What can cause tooth mobility?

There can be many causes of tooth mobility and those may include:

• Bone loss from periodontal disease.
• Biting trauma.
• Tooth clenching.
• Tooth grinding.
• Severe gum recession.
• Orthodontic treatments (temporary mobility)
• Osteoporosis and other medical conditions.

How is dental dehiscence treated?

Treatment for dental dehiscence treatment aims to cover the exposed tooth root to stimulate gingival repair and bone regrowth. Your dentist can achieve some degree of coverage for the exposed root, regardless of the class of your gum recession.

What does fenestration mean in medical terms?

Medical Definition of fenestration 1a : a natural or surgically created opening in a surface. b : the presence of such openings. 2 : a surgical procedure that involves cutting an opening in the bony labyrinth between the inner ear and tympanum to replace natural fenestrae that are not functional (as in otosclerosis)

Can you reverse deep gum pockets?

The key thing to reversing gum disease is removing the tartar that’s present on both the root of your teeth and under your gum line. Periodontitis can’t be reversed, only slowed down, while gingivitis can be reversed.

Are periodontal pockets painful?

Periodontal abscesses usually occur in areas with periodontal pockets, in which deep spaces are generated around the teeth. They cause a dull, gnawing, localized pain but are not painful to percussion. The discomfort ranges from low intensity aches to severe acute pain.

What does junctional epithelium mean?

The junctional epithelium (JE) is an epithelial component that is directly attached to the tooth surface and has a protective function against periodontal diseases. In this study, we determined the origin of the JE using a bioengineered tooth technique.

What is junctional epithelium made of?

The junctional epithelium is found at the base of the gingival sulcus and, in a healthy sulcus, defines this base. The junctional epithelium is made up of mostly flattened epithelial cells that are layered on a basal membrane; only one layer is attached to this basal membrane, and the others adhere to one another.

How long does it take junctional epithelium to form?

Coronal migration of the epithelium from that level accounted for most of the lengthening of the junctional epithelium observed in 3 weeks. During the balance of the experimental period the junctional epithelium did not change in length significantly.
