Abstract

Glass ionomer cement (GIC) is a material used for restoration in dentistry. The stress in a material right before it yields in a flexure test is referred to as flexural strength. The aim of this study was to evaluate the flexural strength of two different glass ionomers after immersion in fruit juices. Five samples of D-Tech and Shofu GIC were prepared from each for the in vitro study. The eight samples were subjected to a flexural strength process and two were left as control which was followed by the determination of maximum force and displacement, then the collected data were used to determine flexural strength and analyzed using SPSS software (IBM SPSS Statistics for Windows, Version 22.0. Armonk, NY: IBM Corp). The mean value of flexural strength of the D-Tech GIC immersed in fruit juices is 4.4375 and the mean value of Shofu GIC immersed in fruit juices was 8.4975. Paired t-test was done between the two groups and the P value was 0.00, which is considered highly statistically significant. From this study, it is evident that the GIC brand Shofu has higher flexural strength compared to D-Tech. Flexural strength was decreased for both the GIC groups when immersed in grape juice.

Keywords: Flexural strength; fruit juice; glass ionomer cement; in vitro study; innovative measurement.
