Subsequent multiple comparisons using pairwise t-tests, showed the Whitening toothpaste to be superior to the DCPD toothpaste (p=0.014) and the PCC toothpaste (p=0.067). When a Box-Cox transformation was made to the data (y0.6) to improve normality, these two differences were more accurately estimated at p=0.004 and p=0.03 respectively.

2018-8-11 Physical Properties of Calcite. Pure calcite is transparent and colorless but also occurs in white, gray, yellow, orange, red, brown, black, or rarely, also blue. Calcite defines the
These include sorbitol, a natural gold alcohol, and sodium saccharin, an artificial sweetener. The advantage of these ingredients is that they give toothpaste a sweet taste without the need for
2019-7-1 Calcium and phosphorous (in the form of phosphate), along with fluoride, are included in toothpaste because they play a key role in keeping your teeth from becoming soft and yucky, which makes it easy for cavities to form. Here are few of the mineral you can find in toothpaste. This mineral is key to fighting tooth decay.
Subsequent multiple comparisons using pairwise t-tests, showed the Whitening toothpaste to be superior to the DCPD toothpaste (p=0.014) and the PCC toothpaste (p=0.067). When a Box-Cox transformation was made to the data (y0.6) to improve normality, these two differences were more accurately estimated at p=0.004 and p=0.03 respectively.
2012-8-11 Calcite One of the most important minerals found in toothpastes is calcite (Calcium Carbonate). This abrasive ingredient is what gives toothpaste its cleaning power. This mineral can be found in sedimentary and metamorphic
There are key ingredients for specialty toothpaste, such as whitening, sensitive teeth, etc. But the following elements are found in most cavity-fighting toothpaste: Fluoride. Abrasives. Flavors. Humectants. Detergents. Learn what each of these ingredients does and
Here we report on the ability of a soil bacterium to synthesize calcite in a calcium-stressed environment. The elaboration of this exocellular crystalline residue enables the organism to regulate its calcium content. The attainment of calcium homeostasis via the exocellular deposition of bacterial calcite with unique crystal habits is a novel
These include sorbitol, a natural gold alcohol, and sodium saccharin, an artificial sweetener. The advantage of these ingredients is that they give toothpaste a sweet taste without the need for cavity-causing sugar. 4. Sorbitol is used in Sensodyne True White, Sensodyne Extra Whitening and the Sensodyne Pronamel range.
Following a baseline examination for plaque, gingival inflammation and bleeding, 75 qualified healthy adult males and females, ages 18-70 were selected to participate in the study. Dental prophylaxis was performed and subjects were provided with two tubes of toothpaste (Colgate Total) and a soft-bristle toothbrush (Colgate Wave Toothbrush).
2004-1-9 The synthesis of calcium carbonate (CaCO 3) crystals from aqueous solutions containing sodium dodecyl sulfate (SDS), poly(N-vinyl-1-pyrrolidone) (PVP) or SDS/PVP complexes has been performed through a slow titration method.It was found that aragonite and calcite coexisted in the prepared crystals. The formation of aragonite in the precipitation
The amount of calcium carbonate used in the compositions should be from about 5% and preferably at least about 10 up to about 60%, more preferably from about 20 to about 50%, by weight, particularly from about 25 to 40% by weight of the detergent compositions. Within the broad range, the lower levels of calcium carbonate may be satisfactory
2016-5-5 Calcite is observed in many ecosystems and plays an essential role in the biogeochemical cycles of both carbon (C) and calcium (Ca). It may be physicochemical or biogenic in origin and numerous organisms have been recognized to control or induce its biomineralization. While fungi have often been suspected of being involved in this process in
2021-4-28 For calcite powder, we use mechanical methods for surface modification: put the ground calcite powder with a fixed mesh into the CLG powder surface modifier, and then add the surface modifier for high-speed kneading. The abrasive is one of the important ingredients in the production of toothpaste, which mainly plays a role in cleaning the
Toothpaste is comprised of powder abrasivus, wetting agent, surfactant, adhesive, spices, edulcorant and other special ingredient. 1.Abrasivus The commonly used abrasives in tooth paste include: ① Calcium carbonate：calcium carbonate is classified into being heavy and light, among which the ground limestone is made by smashing, grinding and refining limestone and calcite
Accessory calcite, present at concentrations between 300 and 3000 mg kg-1, occurs in fresh granitoid rocks sampled from the Merced watershed in Yosemite National Park, CA, USA; Loch Vale in Rocky Mountain National Park CO USA; the Panola watershed, GA USA; and the Rio Icacos, Puerto Rico. Calcite occurs as fillings in microfractures, as disseminated grains within
2015-6-23 Chemical speciation calculations using Pitzer equations are used to assess the potential errors associated with the calcite dissolution kinetics reported by Truesdale (2015). While these errors are shown to be small, agreement between the measured saturation concentration of calcium and the thermodynamic solubility product of calcite is less good.
2003-9-29 Pulses of potassium (K +) applied to columns of repacked calcium (Ca 2+) saturated soil were leached with distilled water or calcium chloride (CaCl 2) solutions of various concentrations at a rate of 12 mm h −1.With increased Ca 2+ concentration, the rate of movement of K + increased, as did the concentration of K + in the displaced pulse, which was less
The results indicated that clays containing 20% of 2 ∶ 1 layer lattice clay minerals are not suitable as precursors of AACs, while those containing 9%–12% of 1 ∶ 1 and/or 2 ∶ 1 layer lattice minerals combined with 29%–32% calcite lead to hardened pastes displaying compressive strengths of up to 12.4 MPa after 2 days and 20 MPa after
2016-10-1 Nano-hydroxyapatite toothpaste was found to be the most effective in achieving dentine tubule occlusion. Dentine disc model is a feasible and non-invasive approach to evaluate the efficacy of desensitising agents and SEM micrographs were able to demonstrate the physical modifications in dentinal tubules.
2022-4-14 The MGI score decreased significantly by 30% among aragonite toothpaste users (p < .0001) and by 18% in the Crest group (p < .0001), indicating the statistically significant improvement of the gingival health of both aragonite and Crest users. The MGI scores of aragonite toothpaste users were 22% lower than the Crest users (p = .0059).
2020-9-23 In general, precipitated calcium carbonate (PCC) is used as a mineral filler in stone industries; while natural calcite (CaCO3) ore is also suitable for industrial use if it is a finely ground high-grade material. Naturally, calcite is found in the form of high- or low-grade ores and it is one of the most widely distributed industrial minerals on the earth’s crust. However, it is rarely
