Performance evaluation of glass ionomer and alumina‐silica nanoparticle reinforced dental composite using preference selection index

Abstract

In this present study, the preference selection index method (PSI) was applied to identify the best formulation among ceramic fillers such as glass ionomer cement (GIC), nanosilica and nanoalumina nanofiller in the dental composites. The comparative assessment of the effect of nanofillers (nanoalumina and nanosilica fillers) and glass ionomer cement has been evaluated. Dental composites with 0, 10, and 20 wt% of nanoalumina, nanosilica and glass ionomer cement were fabricated. These composites were analyzed for physico‐mechanical and wear properties. The PSI multi‐criteria decision making technique was used to rank the composites with various filler content. The performance defining attributes for the comparative assessment were set as void content, hardness, compressive strength, flexural strength, diametral tensile strength, and wear properties against load and speed. The PSI of dental composite reinforced with 20 wt% nanosilica (DCSi‐20) was maximum (0.896) followed by dental composite reinforced with 20 wt% glass ionomer (DCGi‐20) (0.889) and hence DCSi‐20 demonstrated as most preferred dental composite material followed by DCGi‐20. DC‐0 showed the least preference dental composite materials on the basis of desirable physical, mechanical, and wear properties. Finally, it can be concluded that despite of more void content and low flexural strength, overall performance of glass ionomer is comparable with nanosilica and more significant with respect to nanoalumina.

Tests of Dental Properties of Composite Materials Containing Nanohybrid Filler

“…Nevertheless, they have a different chemical nature due to the various other ways of incorporating oxygen atoms into their structure: they contain ester, ether, or hydroxyl groups, which translates directly into the physical and mechanical properties of the preparations. Additionally, the presence of secondary amine structures, as well as hydrocarbon chains and rings, influences their properties [39].…”

Multi-criteria decision making is an important tool to find the best composition of materials from a number of available alternatives [25][26][27][28].…”

An overview of advances in glass ionomer cements

“…Numerous nanofillers have been experiments with the GICs to modify their characteristics and clinical performance. The nonofillers used in GICs including nanohydroxyapaptite [20][21][22][23][24], silica [25][26][27][28], titanium [29][30][31][32], zirconium [33], Barium Sulfate nanoparticles [34], etc. Nicholson et al (1993) [35] first investigated the impact of hydroxyapatite addition to GIC in 1993 and their findings have since guided subsequent research in this area.…”
