This process is known as demineralization which if not treated will result in a cavity.
Plaque is found preferentially at protected and stagnant surfaces.
Since lp(a) is a surrogate for collagen it rushes in to hold the fort by substituting for damaged collagen [pauling]. Local environmental factors which influence the establishment and Below plaque resides a bacterium that produces acids. Dental plaque is a biofilm that attaches to tooth surfaces, restorations and prosthetic appliances (including dentures and bridges) if left undisturbed.understanding the formation, composition and characteristics of plaque helps in its control.
An acquired pellicle is a layer of saliva that is composed of mainly glycoproteins and forms shortly after cleaning of the.
As i understand it, plaque formation is initiated by damage to the endothelium. The attachment, growth, removal and reattachment of bacteria to the tooth surface is a continuous and dynamic process. Formation/development of dental plaque pellicle is the initial organic structure that forms on the surfaces of the teeth and artificial prosthesis. Plaque is differentiated from other deposits such as calculus and material alba on the tooth surface.
Stages of formation in dental plaque 1.
Demonstration of fibronectin in the enamel pellicle]. The first stage in pellicle formation involves adsorption of salivary proteins to apatite surfaces. [article in japanese] takeuchi h, hori y, yu sf, fujii t, sato m, namikawa i, tatsumi m, takagi n. Local environmental factors which influence the establishment and composition of the ultimate plaque community are therefore of greater importance than initial adhesion per se.
Dental plaque is a complex biofilm that accumulates on the hard tissues (teeth) in the oral cavity.
[the mechanism of dental plaque and dental calculus formation by fibronectin. Dental plaque biofilms exist on a variety of tooth surfaces including fissues, smooth surfaces and gingival crevices, however they are most likely to be seen in. This results from the electrostatic ionic interaction between hydroxyapatite surface which has negatively charged. When the oral ph drops below 5.5 plaque formation begins to develop.
[mechanisms of dental plaque and calculus formation due to fibronectin.
Additionally, emdogain® caused the periodontal pockets to become shallow with little resorption of the roots, hence rendering the prognosis better [ 23 ]. Saliva is our body’s natural defense. These acids dissolve minerals in the tooth forming weak spots just below the surface of the enamel. The mechanism of action was inferred to be that emdogain® leads to cementum formation post surface resorption whilst concurrently inhibiting inflammation.
Although over 500 bacterial species comprise plaque, colonization follows a regimented pattern with adhesion of initial colonizers to the enamel salivary pellicle followed by secondary colonization through interbacterial adhesion.
The formation of dental plaque biofilms includes a series of steps that begins with the initial colonization of the pellicle and ends with the complex formation of a mature biofilm. The disease mechanisms elicited by ldl and the other causal factors are multifaceted as discussed below, involving lipoprotein retention, inflammatory cell recruitment, foam cell formation, apoptosis and necrosis, smooth muscle cell (smc) proliferation and matrix synthesis, calcification, angiogenesis, arterial remodeling, fibrous cap rupture,. Whereas microbial adhesion to tooth surfaces is a general prerequisite for initiation of plaque formation, microbial multiplication is probably the dominant feature in the.
