In dentistry, calculus or tartar is a form of hardened dental plaque.It is caused by precipitation of minerals from saliva and gingival crevicular fluid (GCF) in plaque on the teeth.This process of precipitation kills the bacterial cells within dental plaque, but the rough and hardened surface that is formed provides an ideal surface for further plaque formation. The main goal is rst to build a mathematical model of the in ammatory process which takes place in the intima (biomolecular process) and then to add to this model the action of the wall shear stress due to the blood ow in the artery (uid dynamics). Previously, plaque formation was considered as a cholesterol storage disease. It is characterized by a remodeling of arteries leading to subendothelial accumulation of fatty substances called plaques. Brush your teeth twice a day, and brush after eating sugary foods. The acids can damage your enamel and the roots of your teeth, leading to gum disease and tooth decay. Meng S, Fang P, Yang X, Wang H. Monocytes and Macrophages in Atherosclerosis.

When you eat carbs and sugary foods and drinks, bacteria feed on the sugars, producing acids in the process. The main goal is first to build a mathematical model of the inflammatory process which takes place in the intima (biomolecular process) and then to add to this model the action of the wall shear stress due to the blood flow in the artery (fluid dynamics). If the cap breaks, and soft plaque ruptures, enzymes are released into the bloodstream. That could be largely because CDC based its findings only on fasting glucose and hemoglobin A1c. If clots are not dissolved, they can break off the original site and get pushed into the smaller vessels. PrevMed website. Part of this hesitancy may be tied to hsCRP’s lack of specificity. Babey SH, Wolstein J, Diamant A, Goldstein H. Prediabetes in California: Nearly Half of California Adults on Path to Diabetes. Upon plaque formation, cells undergo cell death and intracellular amyloid structures become released into the extracellular space. Those acids can cause problems like cavities, gingivitis, and other forms of tooth decay. Without regular cleanings, plaque may harden into tartar, or it may cause cavities, tooth decay, and gum disease. proliferation ofsmooth-musclecells which results in. This pool eventually grows to become soft plaque. Elevation of C-reactive protein in “active” coronary artery disease. 11 The typical IC 50 for acyclovir is 1 µg/mL for HSV, and the breakpoint for acyclovir resistance is an IC 50 >2 µg/mL.
