Release of Fluoride to the Addition of Nanoparticle Zinc Oxide with Glass Ionomer Cements

Abstract

Background: Glass ionomer cement material has high compressive strength and modulus of elasticity, but low fracture toughness, flexural strength, and wear resistance. Purpose: The purpose of this study was to determine the release of fluoride due to the addition of zinc oxide nanoparticles to glass ionomer cements. Methods: The research is experimental laboratories with posttest-only control group design methods using GIC type II samples. The data was analyzed by using one way Anova and Tukey HSD test. Results: The addition of 1 gram nanoparticle zinc oxide could significantly increase GIC fluoride release. At the same time, the addition of 2 g nanoparticle zinc oxide can't increase the fluoride release of GIC compared with GIC. Conclusions: That adding 1 gram zinc oxide nanoparticle powder to the glass ionomer cement powder can increase fluoride release in the glass ionomer cement..
