Abstract
The purpose of this study is to determine the effect of silica-containing toothpaste on dental stains on eggshells. There were three different dental stains tested during this experiment: Coke, coffee, and red wine, as well as three different toothpastes: Arm and Hammer Complete Care plus whitening, Colgate Total Whitening, and Crest Pro-Health. The hypothesis states “if Colgate Total Whitening, Arm and Hammer Complete Care plus whitening, and Crest Pro-Health toothpastes are used on common dental stains applied to egg shells, then the eggshell will become the most white on the stains from the Crest Pro-Health toothpaste, and therefore have a positive change.” In each trial there were the three stains with one of the previously mentioned toothpastes. Each egg was soaked in the stain over night, and then let dry for 24-hours. Each egg was then brushed ten times clockwise and ten times counterclockwise with a pea-sized amount of toothpaste. After completing 30 trials, an ANOVA test and descriptive statistical analysis was taken for that data. Both inferential and descriptive statistical tests suggested that the Colgate Total Whitening toothpaste was most effective at removing the stains from the eggshells; however, the Crest Pro-Health toothpaste had more consistent results overall. In conclusion, the Colgate Total Whitening toothpaste had the most positive effect, therefore having the highest average removal for each stain.
