Where does gingival crevicular fluid come from?
Gingival crevicular fluid is an inflammatory exudate derived from the periodontal tissues. It is composed of serum and locally generated materials such as tissue breakdown products, inflammatory mediators, and antibodies directed against dental plaque bacteria.
How do you collect gingival crevicular fluid?
Furthermore, paper strips are the most convenient and accurate method for gingival crevicular fluid collection, while enzyme-linked immunosorbent assay can be considered the most conventional method for the diagnosis of biofluids.
Is gingival crevicular fluid normal?
GCF is a physiological fluid that is classified as inflammatory exudate by many investigators, and some suggest it is an altered tissue transudate in a normal healthy state (see Figure 1).
What is Crevicular?
Medical Definition of crevicular : of, relating to, or involving a crevice and especially the gingival crevice gingival crevicular fluid.
Is gingival crevicular fluid a transudate or exudate?
Gingival crevicular fluid (GCF), also known as sulcular fluid, is defined as physiologic fluid secreted in the gingival crevice that is classified as inflammatory exudate during disease or serum transudate during health.
Which immunoglobulin is predominantly seen in gingival crevicular fluid?
A portion of the gingival crevicular fluid samples had IgG (15.7%; range: 0-52%) and IgA (2.5%; range: 0-15%) antibody that was significantly elevated compared with serum.
What is GTR in periodontics?
Guided tissue regeneration (GTR) is a technique currently used in dentistry for periodontal surgery, oral surgery, implant dentistry and reconstruction of maxillomandibular defects. The basic premise for this technique is to allow for osseous regeneration prior to soft tissue migration into the area of interest.
Is GCF an exudate or transudate?
Originally, most investigators classified GCF as an inflammatory exudate (18). However, there is evidence to suggest that GCF from clinically normal tissue is an altered serum transudate that only becomes an inflammatory exudate when disease is clinically present (76).
What immunoglobulin is in saliva?
Immunoglobulin A
Immunoglobulin A is the main class of antibodies present in the body secreted fluids such as saliva, tears or mucus from the intestines. It is generally recognized that IgA, due to its dominance in the immune system of mucous membranes, is the first line of defence against harmful environmental factors.
What is the difference between GBR and GTR?
Introduction. Guided tissue regeneration (GTR) and guided bone regeneration (GBR) are surgical techniques performed to regenerate, respectively, the tooth supporting tissues (GTR) and the alveolar bone in edentulous areas (GBR).
How do I put the GTR membrane on?
This is how GTR is done:
- Surgery on gum and bone. The gum is opened with a procedure known as a flap.
- Separating tissues. Once in place between bone and gum, the membrane provides space and time for the bone to heal and start building itself.
- Care during healing.
- After healing.
What is gingival epithelium?
Background. Gingival epithelium consists of three regions: oral gingival epithelium (OGE), sulcular epithelium (SE) and Junctional epithelium (JE). JE is a specialized gingival epithelium locating at the junction of periodontal soft tissue and hard tissue, and attaching to the crown or root like a collar.
Where is gingival crevice located?
Lined by the sulcular epithelium, the area of space between the tooth and its surrounding gingival tissue is called the gingival sulcus. Based on a published study in the Gulf Medical Journal, the sulcus appears as a small V-shaped groove around the base of the tooth.
What is the most common cause of transudative pleural effusion?
There are two types of pleural effusion: Transudative pleural effusion is caused by fluid leaking into the pleural space. This is from increased pressure in the blood vessels or a low blood protein count. Heart failure is the most common cause.
