Evaluation of the Shear Bond Strength of Denture Soft Liner Reinforcement with Copper Oxide Nanoparticles

Abstract

Aim: This research aims to analyze an alteration in the shear bond strength of soft denture lining materials by the addition of copper oxide nanoparticles with various percentages. Materials and Methods: Three groups of 10 were formed from the total of 30 acrylic block samples (25 mm × 25 mm × 3 mm). Ten specimens without any added CuO Nano Filler made up the control group, or Group A; 10 specimens in the second group (Group B) were modified with 0.3% CuO added Nano Filler, while the 10 specimens in the last group (Group C) had 0.5% CuO added Nano Filler. The universal Instron device was utilized to measure each sample, which tested the shear bond strength. In addition, the utilization of a statistical package for social science (SPSS) and the ANOVA evaluation for a statistical testing of the information and a determination of the truthfulness of the statistical hypothesis, respectively. Results: Descriptive statistics for the shear bond strength for the aforemen-tioned specimen categories, which are detailed in Table 1 have shown a change in mean values between groups A, B, and C, with group C being the lowest out of the three groups (0.31±0.043). Conclusions: There is an inverse relationship between the addition of CuO Nano Filler and the shear bond strength.
