چکیده
|
The aim of this study was to synthesize glass ionomer-silk fiber composite and examining the effect of adding natural degummed silk fiber on the mechanical properties of glass ionomer cement (gic). for this purpose, natural degummed silk fibers with 1 mm length and 13-16 μm diameter were added to the ceramic component of a commercial glass ionomer cement in 1, 3, and 5 wt. %. compressive strength (cs), three-point flexural strength (fs) and diametral tensile strength (dts) of the prepared glass ionomer-silk fiber were measured. analysis of variance (anova) was used to compare the obtained results. moreover, sem technique was used for the investigation of the surface morphology of the as-prepared composite and the fractured area. the results showed that the highest compressive strength, flexural strength and diametral tensile strength were obtained using 3, 3, and 5 wt. % of silk fiber, respectively. however, at 3 wt. % of silk fiber, all three measures of strength exhibited a significant increase compared to the commercial gic. therefore, it can be suggested that the addition of 3 wt. % silk fiber to the ceramic component of gic is desired for dental restorations and orthopedic implant applications, where the maximum strength in all three modes of loading would be beneficial.
