My science fair project goes over the effectiveness and safety of natural substances, such as baking soda and activated charcoal, in whitening teeth compared to normal whitening methods or using normal toothpaste.

Question

ASKING A QUESTION
Now you have selected a topic, it is time to ask a question that will guide your research for the next couple of months. The question must be both measurable and testable. Think about your specific sub-topic and your topic statement from above. Brainstorm 3 problems that you can research, test, and measure. Do some research and brainstorm how you will test and measure each problem.

Problem 1: Does baking soda effectively whiten teeth without causing tooth erosion.
Notes: Investigate the whitening effect of baking soda compared to normal whitening methods.
Testable? Yes or No: Yes
How? : It is possible to conduct an experiment using discolored eggs that represent teeth treated with a baking soda paste for a week.
Measurable? Yes or No: Yes
How?: We can measure the degree of whitening by determining the color change using a dental shade guide before and after the treatment.

Problem 2: Does the use of activated charcoal as a toothpaste alternative result in visible teeth whitening.
Notes: Determine the ability of activated charcoal to whiten teeth over a specified time period.
Testable? Yes or No: Yes
How? : Someone could use activated charcoal toothpaste frequently for a month and then determine results.
Measurable? Yes or No: Yes
How?: Make initial and final assessments using a dental shade guide to measure the changes in tooth color.

Problem 3: How could hydrogen peroxide concentration impact the whitening effect on teeth?
Notes: test different types of concentration of hydrogen peroxide on stained eggs.
Testable? Yes or No: Yes
How? : Use varied concentrations of hydrogen peroxide on stained eggs in a controlled environment.
Measurable? Yes or No: yes
How?: After, compare the color change using a guide of teeth color for more accurate observations.

Read this and answer the following:
RATIONALE: Include a brief synopsis of the background that supports your research problem and explain why this research is important and if applicable, explain any societal impact of your research.

Answer 1

Rationale

The quest for whiter teeth has led to a myriad of dental products and home remedies, with individuals increasingly seeking effective and natural alternatives that promise similar results to commercial whitening agents. This trend stems from a growing consumer awareness regarding the potential adverse effects of chemical whitening agents, including gum irritation, tooth sensitivity, and long-term enamel erosion. Consequently, there is significant interest in evaluating the effectiveness and safety of natural substances like baking soda, activated charcoal, and hydrogen peroxide in achieving tooth whitening without compromising dental health.

Natural whitening agents such as baking soda and activated charcoal are readily accessible, inexpensive, and easy to use. However, their effectiveness and safety in actual tooth whitening are often debated and inadequately researched within the scientific community. For instance, while baking soda's abrasiveness can help remove surface stains, there are concerns that overuse may lead to enamel erosion. Similarly, while activated charcoal has gained popularity on social media as a "miracle" whitening agent, substantive, empirical evidence examining its efficacy and potential risks remains limited.

The examination of hydrogen peroxide, a common active ingredient in commercial whitening products, highlights the need to understand the impact of its concentration. Different strengths yield varied results and can also influence potential side effects. By addressing the question of how concentration affects the whitening effect, this research will not only contribute to dental knowledge but also assist consumers in making informed choices about their oral health.

Research in these areas is important as it can lead to the discovery of safe, effective, and accessible whitening methods. Moreover, it can impact public health by promoting safe dental hygiene practices, ultimately reducing potential dental issues linked to harsh chemical products. By providing clear, evidence-based findings, the project aims to empower individuals with the knowledge to enhance their smile confidently, while also advocating for the responsible use of both natural and commercial whitening methods. Ultimately, a better understanding of these natural substances can lead to innovative, safer alternatives in the cosmetic dental market, promoting healthier choices for consumers worldwide.
