[EO-29] THE INFLUENCE OF ADDING NANOSILICA (THALASSIOSIRA SP DIATOM EXTRACT) ON THE COMPRESSIVE STRENGTH AND TENSILE STRENGTH OF GIC LUTING MATERIAL
[Abstract]
[Objective]
Compressive strength and tensile strength of GIC is a crucial mechanical property that determines its performance in various dental applications. The factor such as natural additions can also influence the mechanical properties of GIC.1,2 Research has shown that diatoms extract possess porous silica cell walls known as frustules.3 This study aims to determine the influence of adding nanosilica (Thallasiosira Sp diatom extract) on the compressive strength and tensile strength of GIC luting material.
[Method]
This research is an experimental laboratory study, using the post-test only control group design. The samples in this study were devided into 5 treatment groups: RMGIC group, GIC without the additioon of nanosilica, addition of nanosilica at 1%, 3%, and 5% rations of nanosilica to GIC. The compressive and tensile strength levels of GIC material with the addition of Thalassiosira Sp diatom nanosilica were measured using a Micro Vickers Hardness Tester.
[Results and Discussion]
The lowest compressive strength value was found in the sample of GIC with 1% nanosilica addition (31.80±5.63), while the most optimal compressive strength value was found in the sample of GIC with 3% nanosilica addition with an average of 58.60±7.12. For the tensile strength, the lowest value was found in the sample of GIC with 1% nanosilica addition (0.66±0.05), while the most optimal tensile strength value was found in the sample of GIC with 3% nanosilica addition with an average of 1.3±0.00. There is an influence of adding nanosilica (Thalassiosira Sp diatom extract) on the compressive strength and tensile strength of GIC luting material with the addition of 3% nanosilica.
