Hardness of Demineralized Enamel with the Application of Toothpaste Containing Green Tea Extract
Abstract: The aim of this study
was to analyze the influence of toothpastes with or without green tea extract
on the enamel hardness. Human teeth were used as specimens and surface enamel
demineralization by soaking in 1% citric acid. Teeth that have been
demineralized were applied with a toothpaste containing green tea extract with
concentrations of up to 15% on the surface of the enamel teeth and then proceed
with surface hardness measurement using Knoop system. The results showed that
soaking the teeth (enamel) in a demineralized solution has significantly
decreased the hardness of tooth enamel. Applications of toothpaste without (0%)
and with green tea extract 5% or 10% or 15% on the demineralized enamel surface
have increased the enamel hardness significantly. However, no significant
differences were seen between the demineralized enamel and enamel applied with
toothpaste containing green tea 5% or 10% or 15%. It was concluded that the
application of toothpaste containing 5% green tea extract was able to increase
the hardness of demineralized enamel.
