Abstract | ||||
Purpose: The goal of this study was to assess the effect of incorporation of micro and nanoparticles of Aloe Vera extract on the flexural strength, surface properties and microbiological assay of an experimental resin composite. Materials and Methods: An experimental resin composite was prepared into which the silanized micro and nano aloe Vera filler particles were incorporated with different concentrations (10, 15 and 20 wt. %). Moreover, a commercial resin composite was tested as control. Specimens of the experimental and control composites were prepared in stainless-steel molds for flexural strength, surface properties and microbiological assay testing. Results: Regarding flexural strength and roughness test results, the control group recorded the highest mean value, followed by the micro Aloe Vera filled composite while the nano Aloe Vera filled composite groups recorded the lowest mean values. Vickers hardness test results revealed that the control group recorded the highest mean value, followed by nano Aloe Vera filled composite however, micro Aloe Vera filled composite groups had the lowest mean values. The nano Aloe Vera filled composite had the highest antimicrobial activity in the microbiological evaluation, followed by the micro Aloe Vera filled composite while the control group showed the lowest mean value. Conclusion: The incorporation of micro and nanoparticles of Aloe Vera extract improved the surface roughness and microbiological properties of the experimental resin composite however, the flexural strength and surface hardness were negatively affected. | ||||
