Innovative biocomposite development based on the incorporation of Salvadora persica in acrylic resin for dental material

Abstract

A novel biocomposite with poly(methyl methacrylate) as resin containing Salvadora persica powders was elaborated. In this study, for the first time, S. persica was used to enhance the bioactive performance of dental restoration materials. Material characterization was carried out both on bare materials and on the elaborated biocomposite (30 wt% of S. persica). X-ray diffraction, Fourier transform infrared spectroscopy, differential scanning calorimetry, and high-performance liquid chromatography techniques were conducted to perform material characterization. The obtained results linked to dental material showed the presence of the organic chemical compounds of S. persica, which are responsible for biological activities, and the presence of mineral chemical compounds of S. persica, which are useful for dental applications and health. They also revealed the absence of toxic residual monomers. In addition, they proved the antioxidant activities proof of elaborated composite related to total polyphenol flavonoid content. Finally, they exhibited the antibacterial activity of S. persica and the composite.
