Abstract Details

2016, Bachelor of Science, Walsh University, Honors.
The purpose of this experiment was to analyze the demineralizing effects of Colgate Optic White mouthwash on hydroxyapatite tooth enamel. Nano-hydroxyapatite particles were used to make 10% solutions with RO water, artificial saliva, 2% hydrogen peroxide, and Colgate Optic White mouthwash. Small samples from these solutions were centrifuged to create an artificial tooth that was examined for demineralization upon being treated RO water, artificial saliva, 2% hydrogen peroxide, or Colgate Optic White mouthwash. Demineralization of the samples was measured by UV-Vis spectroscopy and calcium concentration was measured to compare demineralization among the four different solutions. Calcium standards and validation samples were prepared to make a calibration curve at a wavelength of 652 nm. The results of this experiment showed that calcium concentration was determined to be greatest in samples treated with Colgate Optic White mouthwash and least in samples treated with artificial saliva. RO water and 2% hydrogen peroxide both showed calcium concentrations greater than artificial saliva, but less than Colgate Optic White mouthwash. Colgate Optic White mouthwash significantly demineralizes more than the other three solutions and there was not any significant difference between RO water and 2% hydrogen peroxide. Artificial saliva demineralized the least out of the four groups, which was expected. These results lead to the conclusion that 2% hydrogen peroxide and RO water can demineralize to the same extent and Colgate Optic White mouthwash must contain an ingredient other than 2% hydrogen peroxide that promotes demineralization. This is significant because whitening mouthwash is commonly used by Americans to whiten their teeth, however, they are unaware that their enamel is being damaged. Having the knowledge of this and investigating the products one uses is the key to maintaining one’s oral health and preventing enamel erosion.
