Hypothesis

What happens to your teeth if you don't brush them and consume acidic liquids?

Independent variable: the experiment will have four types of liquids (orange juice, coke, sparkling water and water with lemon.) Each liquid will be placed in two jars. We will be placing an egg in each jar. One which will be brushed every day, and the other will not be brushed every day.

Dependent variable: The softness of the eggs and the acidity of the liquid.

Hypothesis: I think the teeth will be affected because due to the lack of brushing of the teeth and the acidity of the liquid

I will be using eggs for my experiment as a substitute for teeth because there is calcium in the eggs shell and teeth enamel.

Research

The liquids tested in this experiment are in general consumed by people every day. For this experiment we will use Coke, orange juice, sparkling water and water with lemon. As well as water as a control substance (neutral PH).

For the sake of this experiment will use eggs instead of teeth as eggshells contain According to the American Egg Board, the shell of the egg is composed of calcium carbonate (about 94%) with small amounts of magnesium carbonate, calcium phosphate and other organic matter, including protein.

Teeth structure is close to the eggshell structure the outer layer of the teeth called enamel and The enamel is the hardest substance present in the human body composed mainly of calcium hydroxyapatite and partly of organic materials (proteins).PH is very important and dental professional want mouth PH to be kept over 5.5 to avoid cavities and for healthier teeth.

For this experiment, very liquid will be placed in two jars. The PH of each liquid will be measured before placing the eggs to establish a first PH reading using PH strips. One egg will be brushed with fluoride containing toothpaste before placing it in the jar and every morning after taking the PH reading.

We will be recording as well the effect of the liquids on the eggshells.

I pick these certain drinks not only by how often they are ordered or drinked daily. But by their acidity. The dentist needed a scale of measurement of drinks to see what drinks are acidic and what are basic and alkaline.

The pH scale is a scale that is ranged from 1 to 14, one being most acidic like stomach acid and fourteen being the most alkaline like drain cleaner.And 7 being neutral like water. This scale is really important to know if you are interested to be a hygienist, So in result I want to know what drinks will affect the egg more than others

Why did I pick an Egg???

In order to understand the similarities between an egg and a tooth, let's talk about the enamel of a tooth. A tooth has 4 layers. The enamel, the dentin, The pulp, and the root. Let me explain why you need to know this. The enamel is the hardest bone in your body. Your enamel is that white layer covering the inside of the tooth. The enamel is used for chopping up food and gives a shield to the inner parts of the tooth. but just because it is the strongest part of your body it can't be broken. The emmanuel can not be repaired because it is not a living tissue. So If you drink unhealthy drinks you can have a cavity or maybe even a root canal! But if you brush every day you can remove

How does my topic solve a problem

As mentioned earlier, a healthy mouth PH should be over 5.5. This experiment is to show the effect of acid liquids consumption effect on human teeth. The liquids we are using in this experiment are common liquids people consume almost every day like coke and orange juice. I’ve chosen Lemon water as well because it has been popular lately as it has been promoted on social media as a healthy drink for weight loss, clear skin and balancing body PH, to see the effect of lemon water on teeth.

The brushing of teeth idea is to show if we brush our teeth every day and let the tooth paste set on our teeth for a bit how would that protect our enamel and would it be noticeable on the structure of the egg or the PH of the liquid (by preventing the egg from losing Calcium and minerals.

Fluoride compounds also play a big role in remineralizing tooth enamel, almost like replacing bricks in a brick wall of a sturdy structure. These compounds are usually sodium monofluorophosphate, sodium fluoride, and stannous fluoride.

This experiment shows the liquids you need to avoid, or brush your teeth daily. If you want to drink acidic* drinks do the following

-drink with a straw Experiment step by step

- do not hold your drink in your mouth for a long time

- finish drink quickly

- wait 2-3 minutes before brushing your teeth

I am hoping this experiment will be helpful to encourage students and staff to brush and avoid drinking acidic and unhealthy drinks

Variables

Independent variable: the experiment will have four types of liquids (orange juice, coke, sparkling water and water with lemon.) Each liquid will be placed in two jars. We will be placing an egg in each jar. One which will be brushed every day, and the other will not be brushed every day.

Dependent variable: The softness of the eggs and the acidity of the liquid.

Procedure

1- Fill 2 jars with the same liquid. Do that for all of the liquid.

2- Measure the acidity of each liquid before placing the eggs.

3- Place an egg in each jar.

4- Brush only one egg of each liquid( make sure to use toothpaste that contains fluoride) every day

5- Label each jar with the fluid content and the eggs condition (brushed and not brushed)

6- Record the acidity of the liquid every day in each jar for 4 weeks.

7- Record and photograph the physical changes on each egg.

Observations

Analysis

Conclusion

obsrevations

I noticed that every day of each liquid that the pH started to rise as the days went on. But the brushed ones were lower than the non brushed ones. My guess was that it was from the days going on, but no! The calcium of the egg was raising the ph. Let me explain. The egg shell has lots of calcium. SO Calcium raise the ph. So if you were drinking like acidic drinks you would have your enamel consumed by the acidity. But if you brush your teeth with fluoride you can help have a healthier tooth. And the more acidic the drink is the more it will drill through your tooth enamel.

results and background reasursh

The results surprised me since I thought it was going to be way different. Let's start with the ph. The ph was a big surprise and i did not expect a lot of things. The one thing that surprised me the most is the orange juice. I thought that the coke was going to have the most damage since the pH of the coke at the beginning was 2ph and the orange juice was 4ph. Then it started to change but only a little bitSo in my conclusion that means that orange juice did not change as much as coke did, as a result of being more acid. Water was the safest and cleanest drink an the best way to save yourself from having to go to the dentist. Water with lemon was ok but i don't recommend drinking it after you brush

how dose my topic anser a question

I answered a question because everyday some people never brush or floss. As a result of having cavities, root canals, gum disease, and bad breath. And they can cause lots of problems in your oral hygiene and health. I recently researched that if you do not brush your teeth the plaque can come inside your body. Causing a lot of stomach pain and a lot of other stuff.

I hope you take this conclusion as a life lesson that you should be more careful with your oral hygiene.
