Beverages Affect Tooth Decay

Introduction: The experiment that is being performed here will give result of how acidic beverages affect tooth decay and how quickly it can happen. The eggs used in this experiment will act as an actual persons tooth and this will give me the result on how the human tooth can decay by drinking acidic beverages. To perform this experiment I had to gather all of the materials that were required, once I got the grape soda, lemonade, needle, eggs, mason jar, measuring cup. For trail I did the exact same thing, which was taking a needle and sticking it through three eggs on each end of the eggs, and extracting the egg's yoke from the core of the egg. The the purpose for the wholes in the top and bottom of the was to create an window effect so the yokes would extract more easily, and so that the eggs would sink and allowing the liquid substances to infiltrate the core of the egg. This would result in both the outer and inner shell of the eggs would be either gain a new coloration of the liquid substance or stay it original color. I later got the mason jars and filled all three of them with two hundred milliliters of water, grape soda, and lemonade. Once this process was finished I took one egg at a time and submerged them under the liquids so that the eggs would be totally under the substances. On the fourth day of the trail I took the pH levels of egg substance and placed my findings in table 4-1 and used table 5-2 as a reference to my findings.

Abstract

How Certain Beverages Affect Tooth Decay

I think that soda pop will erode teeth the worst due to its high acidity level. In my research paper I will explain to you about delicate the tooth enamel and how it can never be restored only protected. We will also investigate the teeth and bone structure in the humans mouths from the time they are born to the time they become a full adult. The teeth changes the years, they also go through a lot, for example. You have to chew and everything that you eat, accept liquid based food of course; however, the teeth have to bit down on all type of textured food. Like hard and soft food, and as they do this for so long they become warn down. So the next thing what causes such heavy erosion and what is the possible solution to this treacherous problem, and that's what I am here for to help find a solution. This is my mission to solve this use the by using the following variables

{Grape soda pop, water,and lemonade} to get a result.

Trail 1

12/11/12 Day 1

The first step that I did was gathered all of my materials. And they are grape soda, lemonade, needle, eggs, mason jar, and measuring cup

The next thing I did was gut 3 eggs using a needle to remove the inside. Putting one hole in the bottom of the egg and the other in the top

I got three mason jars and filled them up with 200mL of fluids. One with jar is filled with water, the next is filled with grape soda, and the other is filled with lemonade.

Once each jar had their liquids it was time to drop the eggs in so that they may sink and completely be surrounded around fluids.

12/12/13 Day 2

I checked on the eggs and they have become slightly coated with color of the beverage.

I noticed that the grape soda egg was darker than the lemonade egg due to the coloration of the liquid substance

The water egg is looking the same with not coloration effect once so ever.

But I still do think the grape soda will do the most damage to the egg( tooth), but we will see in the next 5 days

12/13/13 Day 3

The eggs are starting to get darker and lighter, which means that acid erosion is taking effect.

The grape soda egg is the darkest of all and the egg is start to look every ugly and bad

The lemonade egg has some acidity effect, but not as bad as the grape

The water is liking the same with no erosion taken place at all

12/14/13 Day 4

Today is the day that I take the pH level using purple cabbage

First I break off a couple pieces of the cabbage and put them in the blender and added 30mL of water into it

Once the blending was complete I strained the leaves through coffee filter so that I could use it as test strips

I put the strips into the jars to get the pH level and they are listed in the table below

Trail 2

12/15/13 Day 1

Today I start the second trail. I will use the materials listed; grape soda, lemonade, needle, eggs, mason jar, and measuring cup

The next thing I did was gut 3 eggs using a needle to remove the inside. Putting one hole in the bottom of the egg and the other in the top

I got three mason jars and filled them up with 200mL of fluids. One with jar is filled with water, the next is filled with grape soda, and the other is filled with lemonade.

Once each jar had their liquids it was time to drop the eggs in so that they may sink and completely be surrounded around fluids.

12/16/13 Day 2

As I was examining the eggs today I seen that the grape soda egg is becoming very dark

The water egg is still looking the same, there is no damage to the outer shell

The lemonade egg is continuing to look yellowish , which is the color of the liquid substance.

12/17/13 Day 3

The water egg is still looking the same with no erosion on it at all

The lemonade egg is still continuing to color and get eroded

The grape soda egg is becoming darker and darker by the day

12/18/13 Day 4

Today is the day that I take the pH level using purple cabbage

First I break off a couple pieces of the cabbage and put them in the blender and added 30mL of water into it

Once the blending was complete I strained the leaves through coffee filter so that I could use it as test strips

The results in the second trail are the same as the results in the first trail, and the tables 5-2 & 4-1 will be used to show data analysis.

Trail 3

12/19/13 Day 1

I will use the materials listed; grape soda, lemonade, needle, eggs, mason jar, and measuring cup

The next thing I did was gut 3 eggs using a needle to remove the inside. Putting one hole in the bottom of the egg and the other in the top

I got three mason jars and filled them up with 200 mL of fluids. One with jar is filled with water, the next is filled with grape soda, and the other is filled with lemonade.

Once each jar had their liquids it was time to drop the eggs in so that they may sink and completely be surrounded around fluids.

12/20/13 Day 2

Today I am checking all of the eggs to see how vast has the coloration succeed

The grape soda egg is becoming a dark purple which is the color of the soda

The lemonade egg is turning light yellow and taking the color of the lemonade

The water egg is normal coloration

12/21/13 Day 3

The lemonade egg is starting to eroded from the acidity level of liquid

The water egg is looking very normal as usual

The grape soda egg continuing strain the egg with the purple color

12/22/13 Day 4

5

Today is the day that I take the pH level using purple cabbage

First I break off a couple pieces of the cabbage and put them in the blender and added 30mL of water into it

Once the blending was complete I strained the leaves through coffee filter so that I could use it as test strips

All three trails will use table 4-1 & 5-2 to show analytical results.

Conclusion:

As I was performing this experiment I did all of the same steps with no revision to the process and all three trails came back the same with no inconclusive results. So this tells me that the acid found in acidic carbonated beverages is high and the beverage will cause teeth erosion if drunk daily. There was some strong correlation with coloration of the beverages. In dark colored beverages the pH level was higher than the lighter color beverage, which is shown between the grape soda and lemonade. The tap water egg was my control variable and the egg pH level and coloration stayed the same with no tooth decay at all. In conclusion, my result were very conclusive and deemed my hypothesis correct saying that the grape soda egg would cause the most tooth decay and have the highest pH level.
