Investigating the Effect of Different Teeth Cleaning Agents on the Growth of Bacteria
On account of the price and variety of tooth cleaning agents available on the market, an investigation was conducted into the effect of different tooth cleaning agents containing different ingredients on the growth of teeth bacteria. The tooth cleaning agents tested were
Colgate total antibacterial toothpaste with Triclosan (3 pence/ml),
Boots non fluoride toothpaste (less than a penny/ml), Dental care baking soda toothpaste (2 pence/ml) and a twig from a natural toothbrush tree Salvadora persica commonly known as ‘Muswak’ (30 pence for two weeks supply, toothbrush not required as twig carries out the function of a toothbrush).
Gingivitis (inflammation to gingival tissue in the mouth) caused by excessive formation of plaque is not just a problem for children, it continues throughout life as long as natural teeth are in the mouth.
The three most common bacteria that cause dental disease are
Streptococcus mutans, Lactobacillus species, and Actinomyces species.
According to an article titled ‘super toothpaste’ by W. F Lee
(Prevention magazine, Dec 97, p67) it is said, ‘Make room fluoride. A new toothpaste is coming and it promises to strike the kind of blow to gingivitis that made fluoride famous for fighting cavities. The key ingredient Triclosan is a common antimicrobial agent already in wide use in products such as antibacterial soap. Scientists think Triclosan may reduce gingivitis by inhibiting the growth of plaque causing bacteria. In a major study submitted to the FDA, the new
Triclosan-fluoride paste (sold as Colgate total) performed significantly better than standard fluoride only toothpaste in helping to prevent plaque, tartar and gingivitis. This combination of
Triclosan and fluoride is the first toothpaste to earn the British
Dental Association seal of acceptance for fighting four dental problems at once- gingivitis, plaque, tooth decay and tartar.1c Non fluoride toothpastes are suitable for individuals who require a controlled level of fluoride. This would be especially relevant in cases whereby the tap water is heavily fluoridated or the individual is taking fluoride supplements. Baking soda toothpaste, also known as sodium bicarbonate paste kills bacteria that cause plaque and bad breath and acts as a mild abrasive. According to the Journal of
Clinical Denti...

In F. Scott Fitzgerald’s The Great Gatsby, Jay Gatsby provides the reader with a unique outlook on the life of the newly rich. Gatsby is an enigma and a subject of great curiosity, furthermore, he is content with a lot in life until he strives too hard. His obsession with wealth, his lonely life and his delusion allow the reader to sympathize with him.
In F. Scott Fitzgerald's novel The Great Gatsby, Jay Gatsby’s conflicts between passion and responsibility demonstrate that chasing empty dreams can only lead to suffering. Gatsby’s motivation to achieve his dream of prosperity is interrupted when his fantasy becomes motivated by love. His eternal struggle for something more mirrors cultural views that more is always better. By ultimately suffering an immense tragedy, Jay Gatsby transforms into a romantic and tragic hero paying the capital price for his actions. Gatsby envokes a deeper Conclusion sentence
The American Dream had always been based on the idea that each person no matter who he or she is can become successful in life by his or her hard work. The dream also brought about the idea of a self-reliant man, a hard worker, making a successful living for him or herself. The Great Gatsby is about what happened to the American Dream in the 1920s, a time period when the many people with newfound wealth and the need to flaunt it had corrupted the dream. The pursuit of the American Dream is the one motivation for accomplishing one's goals, however when combined with wealth the dream becomes nothing more than selfishness.
As Matthew J. Bruccoli noted: “An essential aspect of the American-ness and the historicity of The Great Gatsby is that it is about money. The Land of Opportunity promised the chance for financial success.” (p. xi) The Great Gatsby is indeed about money, but it also explores its aftermath of greed. Fitzgerald detailed the corruption, deceit and illegality of life that soon pursued “the dream”. However, Fitzgerald entitles the reader to the freedom to decide whether or not the dream was ever free of corruption.

Feces, viruses, staph, Salmonella and hand-foot-mouth disease. These are just a few of the things that can be on our hands from normal daily living. With compromised immune systems, open wounds and other issues, these are very harmful. That is why it is so important to keep proper hand hygiene in mind at all times. Hospital infections affect almost two million people in the United States every year, 100,000 of whom die. Up to 70 percent of infections could be prevented if the health care workers follow recommended protocol (Michigan Health Lab, May 26, 2016). Nobody wants to know that when your food has

Since the early colonization of America, the American dream has been the ultimate symbol for success. In retrospect, the dreamer desires to become wealthy, while also attaining love and high class. Though the dream has had different meanings in time, it is still based on individual freedom, and a desire for greatness. During the 19th century, the typical goal was to settle in the West and raise a family. However, the dream progressively transformed into greediness and materialism during the early 20th century. The indication of success soon became focused on wealth and luxury. The Great Gatsby is a story focused on the deterioration of the American dream. Throughout the novel, Jay Gatsby is shown with a desire to achieve his dream by all means. Utilizing the Roaring Twenties as part of his satire, Fitzgerald criticizes the values of the American dream, and the effects of materialism on one’s dream.
The American dream is an ideal in American literature that has been around for centuries. An idea that your average Joe can go from rags to riches, while finding love and having high social status on the way up the ladder. The American dream can be based off the idea of self-reliance, freedom, and just having a general dream to do something better for your life or for your family’s life. In The Great Gatsby, however, the American dream was more focused on materialistic items such as big houses, nice clothes, and fancy cars. Jay Gatsby started as a poor man in his early life, but ended up being quite wealthy. In his early life, he was very dedicated to his dreams, even writing a daily schedule to better himself. But once he acquired a great deal of wealth, he became blinded by his need for luxurious things, and never truly figured out that money cannot buy love and it cannot buy happiness. That instance is what made the novel tragic. Gatsby thought that having wealth meant he had a chance at getting his old love, Daisy, back.
Detergent comes from the Latin word detergere meaning to clean, it is defined as a cleansing agent. Therefore, water itself is a detergent. This essay looks at soap and soapless (or synthetic) detergents. Both substances we use everyday and have a big market commercially, they effect everyone. Soaps are made from natural products and soapless detergents are produced chemically, each having advantages and disadvantages.

Restaurants have been a part of people’s lives since they first started. However, the restaurant industry is not as perfectly clean and sanitary as people believe. Many things contribute to this, but the most important contributor is the factor of sanitation. Restaurants cannot be trusted in the area of sanitation.
Foodborne illness results from eating food contaminated with bacteria (or their toxins) or other pathogens such as parasites or viruses. The illnesses range from upset stomach to more serious symptoms, including diarrhea, fever, vomiting, abdominal cramps, and dehydration. Although most foodborne infections are undiagnosed and unreported, the Centers for Disease Control and Prevention estimates that every year about 76 million people in the United States become ill from pathogens in food. Of these, about 5,000 die.
