What is gingival crevicular fluid?
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.
Where is gingival crevicular fluid located?
GCF is an exudate of varying composition found in the sulcus/periodontal pocket between the tooth and marginal gingiva. It contains components of serum, inflammatory cells, connective tissue, epithelium, and microbial flora inhabiting the gingival margin or the sulcus/pocket.
How do you collect gingival crevicular fluid?
The first one is performed by placing paper strips over the gingival crevice to reduce trauma. The second method is the intracrevicular technique which is the most commonly used. It may be subdivided into superficial and deep, depending on the depth of strip insertions into gingival sulcus or periodontal pocket [109].
Is gingival crevicular fluid transudate or exudate?
Gingival crevicular fluid (GCF), a serum transudate or inflammatory exudate, can be collected from the gingival crevice surrounding the teeth. As such, the fluid reflects the constituents of serum, the cellular response in the periodontium, and contributions from the gingival crevice.
What type of bone loss creates Infrabony pockets?
Most agree that vertical bone loss and subsequent infrabony pocket formation can occur whenever there is direct extension of inflammation into the periodontal ligament, in the presence of sufficient thickness of bone.
What is gingival margin?
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. The gingival margin (F) is the most coronal point of the gingiva.
What is the difference between Transudative and exudative fluid?
“Transudate” is fluid buildup caused by systemic conditions that alter the pressure in blood vessels, causing fluid to leave the vascular system. “Exudate” is fluid buildup caused by tissue leakage due to inflammation or local cellular damage.
What causes horizontal bone loss in teeth?
The most common cause of bone loss is tooth loss left unreplaced, especially multiple teeth. Jawbone is preserved through the pressure and stimulus of chewing. When that is removed through tooth loss, the bone “resorbs” (reabsorbs) into the body.
What is aggressive periodontitis?
Aggressive periodontitis is a destructive disease characterized by the following: the involvement of multiple teeth with a distinctive pattern of periodontal tissue loss; a high rate of disease progression; an early age of onset; and the absence of systemic diseases.
How is free gingival margin defined?
Is pus and exudate the same?
Exudate is fluid that leaks out of blood vessels into nearby tissues. The fluid is made of cells, proteins, and solid materials. Exudate may ooze from cuts or from areas of infection or inflammation. It is also called pus.
