house paint and artist’s acrylic paint are similar, and acrylic paint can be mixed with the interior paint to create custom colors. If many grimy fingers will lovingly fondle the mural, it may be wise to paint the finished wall with clear acrylic varnish for protection. This is far less intrusive than velvet ropes to separate the public from the artist’s latest masterpiece, and allows for occasional cleaning. Silhouettes Or Stylized Shapes Chalk is a great drawing medium for walls. Not only is
Using a primer before you paint isn’t just another way to spend money. The right primer will make your paint job look better, hiding the kids’ scribbles on the wall, the grease splattered in the kitchen, the smoke stains above the fireplace. Hiding isn’t all it does, either. It smoothes out the surface, seals in saps and color that bleeds from wood, and ensures you use less paint. A quality primer, chosen carefully, will actually save you money. Three Formulas of Interior-use Primers If you've
Fluoridation Water fights against tooth decay SCH3U1-04 Minjae.Kim In year 1945, Ontario became the first province in Canada to add fluoride in to community water supplies. The idea of fluoridated water can help prevent from tooth decay and cavities; however it was the first time in Canada with providing community water supplies with fluoride in it. The human’s teeth are the hardest substance in the human body and 96% of them are made of minerals called hydroxyapatite (Ca5(PO4)3OH) and when
implementation of artificially introducing fluoride into water, a great amount of resistance has taken place. Many people claim that fluoridating community water sources can cause not only dental fluorosis, but a multitude of adverse systemic conditions. This perception has led to many political battles on the subject. The problems associated with fluoride ingestion tend to present when concentrations are higher that generally accepted. In communities with natural high fluoride concentrations, adverse effects
associated with chronic fluoride intake in both children and adults, and whether this should restrict its use in these countries (fluoride). Therefore, the aim of this literature review
Secondly, as described above the overconsumption of fluoride has more side effects then benefits. . Fluoride overconsumption may weaken bones and cause osteoporosis. In the latest issue of Osteoporosis International, researchers report that fluoride consumption from tea and toothpaste damaged one woman's bones. This case describes a 53-year-old British woman with a broken bone in her foot, abnormally dense bones and badly decayed teeth. To prevent bone damage or skeletal fluorosis, in 1986 the Environmental
Water fluoridation involves the intentional dosing of municipal water supplies with fluoride waste products from industry in order to achieve a fluoride concentration of approximately one part in a million by weight. Water that has been fluoridated has fluoride levels that are effective in preventing cavities. Fluoridated water creates low levels of fluoride in saliva that reduces tooth
Fluoride in drinking water has been a hot topic in the past decade. Some communities are all for it and some are completely against it. With such a range of opinions on the matter some organizations have took it upon themselves to present the pros and cons of the fluoride to the public so they can make informed decisions. Often times these surveys are bias to one side or the other, so I shall be giving information on both sides of the issue, the future outlook, and my personal opinion in order to
conditions. Among these conditions are bone and kidney damage, neurotoxicity, dental fluorosis, and endocrine manipulation. While the claims of these adverse fluoride effects are justified and have not yet been scientifically contested, studies have reciprocated in that these conditions only have a significant presence in areas served with fluoride to water concentration of 1.0 ppm or greater. Today, the United States and Canada set water fluoridation at 0.7 ppm (Harding & O’Mullane,
Historical Background The history on adding fluoride to the drinking water is shaped by lies. It was insisted by the government that addition of fluoride to drinking water is safe and that it is necessary. However research conducted by many scientists’ shows that it is not safe to consume fluoride. Surveys have shown that areas where people consume fluoridated water have shown to pose serious health implications. The main reasons for adding fluoride to water is because of the pressure from industries
areas were lower than expected based on rates found in non-fluoridated areas (Ad Hoc Subcommittee on Fluoride). This study ultimately does not prove a connection between fluoride and osteosarcoma, it merely consists of trends with unknown causes. Other studies done on the topic do not find a connection between fluoride intake and osteosarcoma.

Did the trial address a clearly focused issue? Yes the trial addressed a clearly focused issue.They evaluated the efficacy of two treatments for removing fluorosis stains in an area endemic for fluorosis. Was the assignment of patients to treatments randomised? Yes the assignment of the participants to treatments were randomised by a randomization table prepared in advance by an examiner not involved with the clinical study. The participants were first grouped according
Over exposure to fluoride can cause a problem in the male reproductive system. Scientist did many tests on lab rats to see if it affected the reproductive system in all male rats. The overexposure to fluoride damages sperm cells in the men which can have a major effect on reproduction. It can also increase the rate of infertility which could cause problems in having children. The increase in infirmity in couples living in the United States was higher than other places (Connett 12). Many diseases
Statement: Concerns for water fluoridation stem from the toxicity of fluoride, the dangers fluoride pose to the body, and equal declining tooth decay seen for fluoridated and non-fluoridated countries. III. Credibility Statement: It is fact that we all consume fluoridated water regularly; whether it’s through water directly, food, or other beverages, we could very likely be putting ourselves at risk. IV. Preview: A. In reality, fluoride is a highly toxic nuclear waste byproduct that comes from phosphate
Few object to the therapeutic use of fluoride to stop tooth decay, but fluoridation, the addition of fluoride to the public water supply, can spark avid controversy. Most dentists, medical groups, and government officials argue that fluoridation is a cheap and risk-free venture that doubles cavity prevention. In contrast, a small minority of dentists and conservative political groups argue that fluoride is a hazardous, poisonous substance that should not be consumed. Some antifluoridationists
Fluoride is a mineral derived from a naturally occurring element called fluorine. Fluorine is the 13th most abundant component on Earth, and you'll find it all round us in the air and water. Toothpaste comprises fluoride. While hard line anti-fluoride consumers bypass fluoride-enriched toothpaste, most people use it because it's been shown to help avert cavities. It does so by sustaining your saliva which assists to avert the buildup up the tooth plaque that leads to cavities. It also helps to guard
mouth difficulties such as enamel fluorosis and other illnesses. Water fluoridation should continue to be the leading method in the distribuition of fluoride to the general population because of its positive effects on the human body. Beginning in the mid 20th century, many exploratory studies were conducted to express that a certain amount of fluoride in water leads to a decrease in cavities among humans. Being nearly 60 years old, the tests used were rather flawed and this has led to public debate
not knowing what's in it. Fluoride is being used in thing’s that shouldn't be, like water. Water is H2O that people around the drink constantly. Some drink more than others, like athlete’s, manual laborer’s, diabetic’s, and people with kidney disease which are exposed to more fluoride than other’s (12 Reasons). All the other water treatment chemicals are added to improve the water for safe drinking, but fluoride does not. How are we supposed to control how much fluoride goes into our bodies’? It’s

INTRODUCTION: The controversy with community water fluoridation arises from moral, ethical, political and safety concerns with respect to water fluoridation. As far back as 1930, there was a relationship inversely between the levels of fluoride in drinking water and existence of dental caries. Any practice like fluoridation, which uses the public water supply to deliver the medicine violated the medical ethics. The ethical issues associated with the water fluoridation include- balancing risks and
