The constant low-level inflammatory reaction in the connective tissue underlying the junctional epithelium also results in the formation of the Gingival Crevicular Fluid (GCF). The Gingival Crevicular Fluid (GCF) is a serum like fluid that is formed from the post capillary venules of the Dentogingival Plexus which is a dense network of blood ...
Oxytalan fibers are unique to the PDL and are elastic in nature. It inserts into cementum and runs in two directions: parallel to root surface and oblique to root surface. The function is thought to maintain the patency of blood vessels during occlusal loading. Further research is needed to determine the function of oxytalan fibers. [4]
Sub-gingival calculus is composed almost entirely of two components: fossilized anaerobic bacteria whose biological composition has been replaced by calcium phosphate salts, and calcium phosphate salts that have joined the fossilized bacteria in calculus formations. [15] The following minerals are detectable in calculus by X-ray diffraction:
They migrate from the tissues in a specialized exudate called gingival crevicular fluid also known as GCF. Neutrophils are recruited to the gingival crevice area as they are signalled to by molecules released by plaque microorganisms. Damage to epithelial cells releases cytokines which attract leukocytes to assist with the inflammatory response.
Dental plaque is considered a biofilm adhered to the tooth surface. It is a meticulously formed microbial community, that is organised to a particular structure and function. [11] Plaque is rich in species, given the fact that about 1000 different bacterial species have been recognised using modern techniques. [12]
The early lesion displays acute exudative inflammation; exudative components and crevicular lymphocytes reach their maximum levels between days 6–12 after plaque accumulates and gingival inflammation commences [21] with the quantity of crevicular fluid being proportional to the size of the reaction site within the underlying connective tissue.
The gingival cavity microecosystem, fueled by food residues and saliva, can support the growth of many microorganisms, of which some can be injurious to health. Improper or insufficient oral hygiene can thus lead to many gum and periodontal disorders, including gingivitis or periodontitis, which are major causes for tooth failure.
The EA is very strong in a healthy state, acting as a type of seal between the soft gingival tissue and the hard tooth surface. The deepest layer of the JE, or basal layer, undergoes constant and rapid cell division, or mitosis. This process allows a constant coronal migration as the cells die and are shed into the gingival sulcus.
