  1. Dental Whitening Jeremy Bojnowski – Robert Martin Lake Shore High School

  2. According to Linda Dyett, professional whitening costs around $650. • Did you know that there may be a way to obtain a bright smile with the price of just $10? 2 Bojnowski – Martin

  3. Why a Bright Smile? • Avoids being self – conscious • Good impression on others • Attraction 3 Bojnowski – Martin

  4. What Causes Dental Discoloration? • Streptococcus mutans (S. mutans). • Acidic waste. 4 Bojnowski – Martin

  5. S. mutans • Parasitic organism. • Lives on teeth. • Accelerates enamel decay. • Carbohydrate diet. http:/textbookofbacteriology.net/normalflora.html Bojnowski – Martin 5

  6. http://www.webmd.com/oral-health/image-collection-oralhealth#phototake_r m_photo_of_tooth_illustration.jpg The loss of enamel allows tooth coloration to occur 6 Bojnowski – Martin

  7. Substitution for Teeth • Teeth are mainly composed of calcium carbonate • Eggshells are mainly composed of calcium carbonate as well • Therefore, eggs work as a substitute Bojnowski – Martin 7

  8. Oxidation O e-1 H H O H202 Molecule Neutral tea molecule When an atom loses an electron. The size and visibility of the atom are reduced. 8 Bojnowski – Martin

  9. How do People Whiten Their Teeth? • Mouthwash. • Tooth brushing/tooth paste. • Professional dental treatment. 9 Bojnowski – Martin

  10. How do the active ingredients in Vibrant White Pre-Brush Mouthwash from Listerine affect the whiteness of eggs over time? 10 Bojnowski – Martin

  11. Independent Variables Bojnowski – Martin 11

  12. Variables • Solution strength: based off of standard and sensitive mouth treatments • Time: based on whitening tray procedures & professional treatments 12 Bojnowski – Martin

  13. Response Variable • Degree of Whiteness. • Shows the change in whiteness after treatment(s). Bojnowski – Martin 13

  14. What Will Happen? If the recommended dose of mouthwash is applied with the highest amount of time allowed, then the eggs will become whiter than the eggs treated in the standard and lower treatments. 14 Bojnowski – Martin

  22. Experimental Errors • Egg Replacement • Timer Errors • Egg Dying • Human Error 22 Bojnowski – Martin

  23. 23 Bojnowski – Martin

  24. Main Effect of Solution Strength • .39° effect. • Not statistically significant. 2* 3.33 < .39 6.66 > .39 Not Significant Bojnowski – Martin 24

  25. Bojnowski – Martin 25

  26. Main Effect of Time • 1.44° effect • Not statistically significant 2 * 3.33 < 1.44 6.66 > 1.44 Not Significant Bojnowski – Martin 26

  27. Analysis

  28. Bojnowski – Martin 28

  29. Interaction Effect • .054 interaction • Not statistically significant 2 * 3.33 < 1.44 6.66 > 1.44 Not Significant • Shows that combination of variables does not have a significant effect Bojnowski – Martin 29

  30. Were We Correct? If the recommended dose of mouthwash is applied with the highest amount of time allowed, then the eggs will become whiter than the eggs treated in the standard and lower treatments. ACCEPTED! 30 Bojnowski – Martin

  31. What Happened? • Testing effectiveness of the mouthwash resulted in a positive outcome. • Whitening mouth washes were shown to have a whitening effect. Bojnowski – Martin 31

  32. Further Research • Different forms of whitening • Cost analysis Bojnowski – Martin 32

  33. Real-World Application • Dental concerning people • Solution to oral whitening • According to the British Academy of Cosmetic Dentistry, 32% of the world’s population is concerned about their teeth. 33 Bojnowski – Martin
