Abstract

Objective: To compare the fluoride release from Conventional Glass Ionomer Cement (GIC), Resin Modified GIC (RMGIC), and Cention N Alkasite Material. Material and Methods: Forty- five disc-shaped specimens of three different restorative materials (Conventional GIC, RMGIC, and Alkasite material) were made and divided into 3 groups (n=15). Fluoride release was evaluated at the end of Day 1, 7, 14, and Day 28 using fluoride ion-selective electrode. Intergroup and Intra-group analysis was done using One-way ANOVA with a Post-hoc test. A p-value of <0.05 was considered statistically significant. Results: Cention showed more fluoride release (in parts per million) than GIC and RMGIC at increased time duration. However, at the end of day 1, there was lesser fluoride release with Cention, as compared with the other groups. Conclusion: The new Alkasite restorative material showed promising results in terms of fluoride release and is better than GIC and RMGIC at increased time duration.

Highlights

Fluoride is well documented as an anti-cariogenic agent
During the inter-group analysis, Group 1 showed the highest level of fluoride release at the end of day
1, whereas group 3 showed the highest value of fluoride release at all the other time intervals

Summary

Introduction

Fluoride is well documented as an anti-cariogenic agent. There are several mechanisms that play their role in the anti-cariogenic capability of fluoride. Glass Ionomer Cement (GIC) is the most widely used and critically acclaimed fluoride-releasing restorative material [1]. Conventional GIC is a self-cure restorative material that has an advantage of fluoride release and biocompatibility, but its inadequate strength and toughness have limited its use in less stress-bearing areas. This limitation arose the need for newer materials with fluoride release, which includes packable GIC, compomers, giomers, and various new glass hybrid materials [2]. RMGIC has more flexural strength when compared to conventional GIC [3]
