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 is GCF medical?
Like other fluids of the human body, a gingival crevicular fluid (GCF) contains proteins, a diverse population of cells, desquamated epithelial cells, and bacteria from adjacent plaque.
What kind of bacteria is present with gingivitis?
The bacteria associated with periodontal diseases are predominantly gram-negative anaerobic bacteria and may include A. actinomycetemcomitans, P. gingivalis, P. intermedia, B.
What is the difference between transudate and exudate?
“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 is a Transudate?
Transudate is an ultrafiltrate of plasma that contains few, if any, cells and does not contain large plasma proteins, such as fibrinogen. Transudate results from increased hydrostatic or reduced oncotic pressure.
What’s the GCF in math?
The greatest common factor (GCF) of a set of numbers is the largest number that is a factor of all those numbers. For example, the GCF of the numbers 4 and 6 is 2 because 2 is the greatest number that’s a factor of both 4 and 6. Here you will learn two ways to find the GCF.
What does GSF mean in medical terms?
The Gold Standards Framework (GSF) is a framework used by many GP practices, care homes and hospitals to enable earlier recognition of patients with life-limiting conditions, helping them to plan ahead to live as well as possible right to the end.
What is GCF in subjects with periodontal disease?
GCF in subjects with periodontal disease contains inflammatory cells, bacteria, tissue breakdown products, antibodies, and complement system proteins and enzymes, in addition to many inflammatory mediators [ 2
How is GCF collected from the gingival crevice?
The method of GCF collection depends on the kind of investigation to be done on the GCF. Following is the description of commonly used methods for GCF collection, In this technique of GCF collection, the gingival crevice is perfused with a fixed volume of an isotonic solution such as Hank’s balanced salt solution.
How is gingival crevicular fluid used in periodontal treatment?
The process involved installation and re-aspiration of 10 μl of Hank’s balanced salt solution at the interdental papilla. This process was repeated 12 times to allow thorough mixing of the transport solution and GCF. The main advantage of this technique is that it can be used to obtain GCF fluid from a single site or multiple sites.
When was the GCF study of dentogingival structure created?
JPR 1971 : 6; 110 -114. The GCF studies boomed in the 1970s. The rationale for understanding dentogingival structure and physiology was created by the outstanding electron microscopic studies of Schroeder and Listgarten.Saturday, August 11, gingival crevicular fluid 62012
