The Effect of Acidic Candy on Teeth


  • S. Maiti


The trend in the consumption of candy by children has increased since the 1990s in the USA.
Unfortunately, this increased consumption of sweets can lead to negative consequences on oral
and overall health. This investigation considered the effect of acidity on an enamel analogue
consisting of powdered calcium minerals to simulate the effect of acidic candy on teeth. Four
concentrations of 5% acetic acid solution were created (0%, 1%, 10%, 100%) and then allowed
to associate with a known height of calcium powder in a clear tube for 24 continuous hours. The
height of the calcium powder was measured initially and after 24 hours. The differences in height
between the samples were analyzed using an ANOVA test which resulted in an F-statistic of 9.8
and a p-value of 0.089 suggesting a statistically insignificant difference between the difference in
the heights of the samples. There were a variety of challenges with the experimental design
which decrease the level confidence in the results obtained.
