Abstract

Introduction: Considering the importance of glass-ionomer cements (GICs) in dentistry and their poor mechanical properties, the aim of this study was to improve their mechanical properties by manufacturing a glass-ionomer‒carbon nanotube‒BAGHDADITE nanocomposite by adding CARBON NANOTUBEs and BAGHDADITE nanoparticles.Materials& Methods: In the present experimental study, CARBON NANOTUBEs with 0.5 wt% and BAGHDADITE nanoparticles in 1, 3 and 5 wt% were added to the cement component of a commercial glass-ionomer cement (Fuji ІІ GC) for preparing glass-ionomer‒carbon nanotube‒ BAGHDADITE nanocomposite. Then the mechanical properties of the samples were evaluated by the cold COMPRESSIVE STRENGTH (CCS), three-point FLEXURAL STRENGTH (FS) and diametral TENSILE STRENGTH (DTS) tests. In addition, the fractured sample surfaces were evaluated after the COMPRESSIVE STRENGTH test under a scanning electron microscope. Data were analyzed with one-way ANOVA at a significance level of p value<0.05. A total of three samples were evaluated (n=3).Results: Based on the results of mechanical tests, the composite containing 0.5 wt% of CARBON NANOTUBEs and 1 wt% of BAGHDADITE nanoparticles exhibited the highest COMPRESSIVE STRENGTH, diametral TENSILE STRENGTH and FLEXURAL STRENGTH. In addition, SEM micrographs indicated a decrease in pores in the composite structure and a decrease in stress concentration and propagation of cracks, resulting in an increase in the mechanical strength of samples.Conclusion: According to the results, the most appropriate sample for dental and orthopedic applications in load-bearing areas is glass-ionomer cement containing 0.5 wt% CARBON NANOTUBEs and 1 wt% BAGHDADITE.
