wt % and the abrasive is present at a quantitative parity of 0-5 wt % from composition mass.;EFFECT: invention is highly effective at dental deposit removal from a natural teeth and prostheses and does not damage a teeth or a prosthesis owing to excessive touching.;11 cl, 17 ex, 5 tbl...
suggesting that at any time the deposit was constituted by nonapatitic ca-poor caps. the ca/p atomic ratio for md decreased with the soaking time from approximately 1.47 at 7 days and finally to 0.85 after 28 days in sbf, suggesting that the deposit was composed of nonapatitic ca-poor cap...
partially molten calcium chloride at 780° to 800°C in a graphite lined steel vessel. The method requires precise control of temperature and current. The solid deposit of metal produced may contain entrapped salt and impurities such as chlorine and nitrogen. It is re-melted to reduce impurity ...
Dental enamel is also affected (Figure 1d), a finding consistent with amelogenesis imperfecta, which was reported for humans with Orai1 defects.11 These findings suggest that there might be a general defect in mineral-depositing cells in the absence of Orai1. The Orai1À/À bone ...
17. The lead deposit in adult bone can act to replenish lead eliminated from blood by excretion, even long after exposure has ended22,23,24,25,26. It can also act as a source of lead transfer to the fetus when maternal bone is resorbed for the production of the fetal skeleton27,28,...
removal of dental plaque during brushing of the teeth. Calcium carbonate (CC) of natural origin (chalk) or of synthetic origin (precipitated calcium carbonate —PCC—) is one of the oldest dental abrasives; Apart from these calcium-containing abrasives, silica is also largely used in toothpastes...
f2) dipping an oxide layer-coated surface of an object into the microemulsion of e2) to deposit the microemulsion onto the surface, g2) evaporating the organic solvent from the surface of f2) to obtain the coating of nano-sized crystalline calcium phosphate, and h2) heating under inert atmosp...
It constitutes about 2% of body weight, found mostly in bones and teeth. Its concentration in the blood is about 100 mg/L, found in blood proteins and serum.The few limited applications of calcium are mostly in metallurgy. It is used to produce alloys with aluminum, lead, beryllium, ...
