Potassium in the human body is largely located in the cells as the major cation of the intracellular fluid. There is also a small amount of potassium in the

The term Biometal refers to the role of metal ions in biology, biochemistry and medicine. The metals copper, zinc, iron and manganese are examples of metals that are essential for the normal functioning of the body. It is also a term used to describe a living machine.

This morning I woke up and looked in the mirror and noticed that my teeth were not as white as I like them to be. I think to myself, I need to call and make an appointment to get my teeth whitened with my dentist. Teeth whitening is an example of Cosmetic Dentistry. Cosmetic Dentistry is different than regular dentistry in the sense that regular dentistry deals with oral hygiene and the prevention, diagnosing and treating of any oral diseases. Cosmetic dentistry however focuses on improving a person’s teeth, smile, and mouth. General dentistry deals with what needs to be done whereas Cosmetic dentistry is

Throughout everyone’s lives either children and adults, brushing teeth is nessecary to maintain fine-white looking teeth. Yet many people who constantly brush when needed still fall short in achieving white, shiny, teeth even though they brush after every meal. This is due to stains from wines, acidic foods, or the coming of old age. Either one of these reasons could be responsible for why your white-shinny teeth become yellow. Imagine having a fine dinner with your special someone, only to smile and have them see your ugly, disgusting, yellow colored teeth. With 3D White Strips made by Crest, say goodbye to those ugly teeth and say hello to shiny, sparkly, white teeth. When people ask other people “How did you get your teeth so white?” Most

Electrolytes are compounds that dissociate into ions when they are dissolved in water, thereby causing them to become electrically charged particles, meaning that they have the ability to conduct electrical impulses. The electrical impulses created are what the body needs in order to make muscle cells contract. Electrolytes can become either cations (positively charged) or anions (negatively charged).

So what is the chemistry behind teeth whitening? All teeth whitening products contain hydrogen peroxide, which serves as a bleaching agent. The hydrogen peroxide goes through the surface of the teeth and oxidizes the organic composites (which are the cause of teeth staining) that exist in the tooth enamel. The oxidation of these organic composites results in smaller remaining

The sodium in our body plays a very important role in the fluid outside of our cells (extracellular fluid) (5). Sodium found here is vital because it helps preserve the volume of our plasma and this gives suitable fluid to pass over or through the vessels of different organs, and also allows for natural metabolism (4). Sodium is usually used as an extracellular cation, and because of this it is typically located in the blood and lymph fluid (5). The preservation of this extracellular fluid is a crucial role of the sodium found in the body (5). Another important role that sodium has in our bodies is when the concentrations of sodium and chloride ions change it allows neurons to send signals to each other and to other cells (5). This exchange of signals assists with nerve transmission and mechanical movement (5). The fact that this element aids in helping our bodies function properly is one major reason that sodium is the best

In spite of this, a deficiency in this mineral may be the basis of more diseases than any other nutrient. Magnesium is the most critical mineral required for the electrical stability of every single cell in our bodies. Are you beginning to grasp the importance of this mineral?

Magnesium is needed for more than 300 biochemical reactions in the body. It helps maintain normal muscle and nerve function, keeps heart rhythm steady, supports a healthy immune system, and keeps bones strong. Magnesium also helps regulate blood sugar levels, promotes normal blood pressure, and is known to be involved in energy metabolism and protein synthesis. There is an increased interest in the role of magnesium in preventing and managing disorders such as hypertension, cardiovascular disease, and diabetes. (How Many Americans Are Magnesium Deficient)

1. Introduction a. Attention Getter: According to a survey published by Delta Dental on the Colgate Website, nearly seven out of ten Americans brush their teeth at least twice a day but more than 30% aren’t brushing enough. Additionally, 23% of Americans have gone two or more days without brushing their teeth. b. Revealed Object and Credibility: This toothbrush represents the dental world as a whole.

Discolored teeth may affect self-esteem of individuals depending on the society they live in.(1) The demand of individuals for tooth whitening existed for centuries, since ancient Asians, some first century Romans and during the 1300s by barber surgeons as well. (2-18) A lot of significant efforts have been directed toward understanding the nature of tooth discoloration and devising methods to eliminate them. (1) Of these methods, veneers and full coverage crowns are considered most invasive, because sound tooth structure is removed to create room for the restoration. (1) Tooth bleaching is the most conservative and cost-effective treatments that could improve a person’s smile, by dissolving discolorations in patients dentition using oxygenating

Do they even work? Are they worth the money? As whitening strips and other whitening agents become more and more popular, there are questions on the safety of these products and if there really is a true change in your smile. Whitening strips are the most widely used do-it-yourself whiteners, used for fixing stained and discolored teeth (Humana, 2014). In this paper, I’m going to show the research done on the effects of whitening strips, their effectiveness on people, along with the safeness of these products on humans and the surrounding environment.

Have you ever seen magnesium? That’s because it can’t be found in the earth’s crust to the naked eye. Though it’s a pretty silvery white color. Bet you didn’t know that it’s in cattle feed, that’s random. In 1775, Joseph Black discovered magnesium while mixing electorally ceased mixture if mercuric oxide and magnesia, in Thessaly Greece. Magnesium is 30% lighter than aluminum. Bored yet? Stay with me, this is only the beginning.The chemical properties of the surface of magnesium is a metal covered with a thin layer of oxide that helps protect the metal from attack by air. Magnesium combines with oxygen at room temperature. It burns with a blinding white light when at higher temperatures. At the time when water reaches 1,994 degrees’ Fahrenheit

Manganese (symbol Mn) is the fifth most abundant metal in the world. It is not found as a pure element in nature, rather it is bound to oxygen or other elements. Johann Gottleib Gahn, a Swedish mineralogist, is credited as the first person who was able to isolate the metal Mn from the dioxide MnO2. (chemistry explained). Manganese has a great many uses in the industrial world. Manganese is used in the production of iron, steel, dry cell batteries, coins, as an additive in unleaded gasoline, and as a coloring agent for glass and ceramic (education).

Many times the assumptions made by the companies need to be either verified or revisited. The Harvard professor Robert Kaplan states that ‘most decisions are based on an underlying assumption. Positions articulated in a debate are based on an assumption. The problem is that, too often, in business, the assumption is never made explicit, or if it is, its accuracy is never questioned’ (qtd. in “Never Make Decisions Based On Assumptions”). Well, the most important estimation that Goodbite did was their claim that white strips are most needed by people from 20 to 29 years old. This perception, though, on the one hand may be true but from the other, I believe that it is not too accurate. The fact that people aged from 20 to 29 want to whiten their teeth is displayed by some routines from their personal activities that probably are yellowing their teeth. Those are likely to be the excessive use of tobacco (smoking cigarettes) and the fact that they often drink coffee or tea. Through this opportunity, they may find an extra way becoming more attractive, beautiful and handsome. One of the things that a man first see to another are the teeth, quite reasonable if anyone thinks that it is the most visible part of our body. So, making a positive first impression to a person seems an important factor for someone to use white strips. Thus, I am convinced that youngsters whiten their teeth not only
