Literature Research Paper
Introduction/General Background
For my research project, I am researching if tea stains your teeth. The factors involved in this investigation will be researching egg shells, what they are made of, and their similarity to teeth. I will also be researching tea, and what it’s made of, and how it may or may not stain teeth/egg shells. The variables that I will be investigating will be types of tea, and the length of time the shells are spent in the tea. I am conducting this research project in order to discover if tea stains your teeth. If it does, then I would also like to find what kind of tea stains more and why.
Analysis of Prior Research and Explanation of Scientific and Technical Concepts
While tea is often considered to be coffee’s gentler cousin, but when teeth are involved this may not be the case. Some black teas may actually stain teeth more than coffee. Similar to red wine, black teas tend to have a very high tannin content, which contributes to teeth staining. Therefore, teas with a lesser tannin content, such as green, white, and herbal tea, are much less likely to stain teeth. Herbal tea, on the other hand, still was found to erode

tooth enamel much more than black tea. Black tea can stain teeth. The tannin in it transfers to tooth enamel. Green tea also stains, but not as much. Tannin solutions are acid and have an astringent taste. Tannin is what is responsible for the astringency, color, and some of the flavor in tea. Tannins are found most often in the roots, bark, wood, and fruit of many plants. According to Arwen Hann, from Colgate, says that tea is actually more likely to stain teeth than coffee.
Drinking tea can cause lasting discoloration, but it is possible to reduce staining by developing healthy oral care habits. Teeth are structures in the mouth that are individually squares or cubical-shaped with grooves intended for use in breaking down food for consumption. Teeth are naturally white or off-white in color, but build-up from foods and drinks such as coffee and tea over time can stain the white color and turn teeth yellow and discolored. Tea does stain your teeth, especially if you drink it on a regular basis. Tea contains tannic acid, which can create small pores in the enamel of your teeth. The pigment from tea then collects in these pores causing deep stains in the
enamel. Tea contains a substance that is called tannic acid. This is what gives tea it’s dark color. A person with grooves on their teeth, will have tannic acid settle into them, causing discoloration over time. Certain brands of bottled and sweetened teas contribute to dental erosion because of their sugar content. As you drink these types of teas, your teeth are bathed in sugar, which encourages erosion and dental cavities. The Academy of General Dentistry reports that canned and bottled iced teas can permanently damage your tooth enamel, which will soften your teeth and increase your risk of tooth loss and cavities. Unsweetened tea is a healthier option that does not include sugar. Dentists say that tea, especially the basic black variety, can cause more stains than coffee. Herbal and white teas can wear away the outer covering of your teeth, called enamel, and cause stains too.
The purpose of this experiment was to identify which brand of mint gum holds its flavor the longest. The four brands I chose were Orbit, Trident, Ice Breakers, and Wrigley's Doublemint My hypothesis was that Trident brand would last the longest and Wrigley's Doublemint would last the shortest. I did not use any people in my test. I chewed the same amount of gum at a time and the gum was all the same flavor, mint. All the gum was bought at the same time from the same store. I chewed the four brands of gums between periods of time. When chewing, I timed myself with a stopwatch. When I believed the gum ran out of flavor, I stopped the timmer and recorded the time. My hypothesis was incorrect. Instead of Trident, Orbit lasted the longest. However
Dependent variable: We are measuring the time taken for the pink indicator to turn clear when hydrochloric acid is added to it. Independent variable: We are changing the molar of hydrochloric acid we are adding to the gelatine cubes. The molars range from 1-3.
As you should know our mouth are full of bacteria and also not to mention mucus and other particles. When you don’t keep up with your daily cleansing of your teeth and gum, the bacteria, mucus and the particles build up to become plaque on teeth. With brushing and flossing daily removes this plaque buildup. If you choose not to keep up with daily brushing and flossing the plaque hardens and becomes tarter on the teeth. The tarter cannot be removed with brushing or flossing. In this case you will need to see a dentist or dental hygienist. When ...
These to conditions are caused by the type of diet the person has. If the person has an unhealthy diet it is more likely that they will suffer from teeth staining and foul odor The type of beverages a person consumes also play a big factor in both staining and bad breath . Other factors may be causing these conditions such as having medical problems. At times bad breath and teeth staining can be a sign to the person that they may have a problem in the mouth that is causing the bad breath such a root canal or an infected tooth. In order for the person to prevent this from happening in the future the person should retain from eating foods and beverages that are known to cause bad breath and teeth staining. Proper oral care is needed so it the mouth stays clean from food and

The scientific findings needs to be used are the following, variable which is a logical set of attributes. The attributes is a characteristic or quality of something. For example, the attributes towards my study, would be the ages of both sex genders from college students and parent 's. Due to the fact, if there 's a chance of inheriting alcohol behavior to consume during the adolescence to young adulthood. "The implication of the level of measurement would be analyses require a minimum level of measurements and some variables can be treated as multiple level of
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 Protection Agency set 4 milligrams per liter (mg/L) as water fluoride's maximum-contaminant-level. In 2006, the National Research Council reported that 4 mg/L is too high to protect health. Yet, some brewed teas contain almost twice that concentration. It can actually be dangerous to consume with resulting health consequences such as neurotoxicity, cancer, and fluorosis among others. Dental fluorosis results in staining and pitting of the teeth with some enamel damage possible at advanced levels. Skeletal fluorosis is a more advanced and serious case of fluorosis and results in pain and impairment of joints, muscles, and tissue. Chronic intake of excessive fluoride can lead to the severe and permanent bone and joint deformations of skeletal fluorosis. Early symptoms include sporadic pain and stiffness of joints: headache, stomach-ache and muscle weakness can also be warning signs. The next stage is osteosclerosis (hardening and calcifying of the bones), and finally the spine, major joints, muscles and nervous system are damaged. The fluoride ion (F-) is extremely reactive and strongly attracted to calcium.

The design for this study will be a simple between subject experiment consisting of one experimental group and one control group. The independent variable will be warm colors. The dependent variable will be mood. The main goal is to determine if the independent variable will influence or cause difference in the specified dependent variable. The experiment group will spend 60 minutes in a warm paint color room and their mood will be measured. The control group will spend 60 minutes in a neutral paint color room and their mood will be measured.
I picked the science experiment elephant toothpaste this year, because it seems interesting and fun. It is also a way to test if the removal of oxygen in these experiments will actually work. I have four different experiments. Two out of the four experiments I am testing, is to see if there is a different reaction time and size between yeast and potassium permanganate and the percentage of the hydrogen peroxide. My third and fourth are tests of elephant toothpaste is to see if adding cornstarch has a color reaction to the potassium iodide to make it look like it is “glowing”, or if the yeast and fluorescent dye will make it look “glowing”. I think the elephant toothpaste that uses 50% hydrogen peroxide and potassium permanganate will have the
Teeth whitening is an ever increasing procedure being requested by many patients. In this paper, I will be discussing the biological and chemical mechanisms of teeth whitening, the difference between in office and take home whitening, current products on the market, and current issues and safety concerns regarding teeth whitening. Knowledge of these topics is important to have to be able to safely recommend in office or at home whitening options.
While tea is said to be healthier, it is the second most consumed morning beverage. Why is that? On an average day, only one in five American adults drink tea. The average tea drinker takes in more than twenty times more flavonoid antioxidants per day than non-tea drinkers. So those non-tea drinkers are missing out on their daily helping of flavonoid. Caffeine in tea isn't as much of an issue as it is in coffee.
While ulcers are now believed to be caused by the Helicobacter pylori bacteria, many medical experts are pointing to the acidic effect coffee has on the stomach which weakens the lining and allows H. pylori to take hold and wreak
Lastly, a common side effect of coffee we all may have experienced is the staining of teeth and dehydration. After a while, without proper care coffee can permanently stain and damage your dental. Also the caffeine in coffee is a mild diuretic and can increase the volume of urine excreted. However, this effect can be easily counteracted by the drinking of an extra glass of
Coffee people drink coffee with a purpose, they need the caffeine to make them more alert and increase their productivity. On the other hand, tea drinkers usually drink tea because of the enjoyment that tea give them, the relaxations that tea provide. It is typical to imagine that a person holding a cup of coffee is working over night at an office and a tea person is often reading newspaper at Sunday afternoon. Unlike tea drinkers, coffee drinkers are more attached to their drink compared to tea drinkers. A coffee drinker must have his coffee fix every single morning otherwise he or she cannot function without it. However, a tea drinker can easily live without drinking tea for even a few days. Even though they both have caffeine inside their drink, coffee drinkers seem to be more addicted to caffeine and as time goes, they will become more dependent on
