Abstract

This study explores the enhancement of properties in zirconia-based ceramic dental restorative materials through the incorporation of baghdadite (Ca3ZrSi2O9) and zinc oxide (ZnO) nanoparticles. Baghdadite was synthesized via a solid-state sintering method and integrated into zirconia to form baghdadite/zirconia ceramic composites. These composites were sintered with varying concentrations of baghdadite (0%, 5%, and 10%) to enhance bioactivity and support bone tissue repair, and incorporated with 0.6% ZnO nanoparticles to improve antimicrobial properties. The crystallographic structure, surface morphology, apparent density, antibacterial properties, and cell viability were characterized using x-ray diffraction (XRD), scanning electron microscopy (SEM), Archimedes principle, agar plate method, and trypan blue exclusion assay, respectively. Protein adsorption was evaluated using bovine serum albumin (BSA). Results showed that higher concentrations of baghdadite increased protein adhesion on the surface. The agar plate method revealed that ZnO nanoparticle-reinforced zirconia/baghdadite composites exhibited significant antimicrobial activity, particularly against Staphylococcus aureus and Escherichia coli. In addition, the composites demonstrated a significant high cell viability of 83.71%, promoting cell growth. These findings suggest that the incorporation of baghdadite and ZnO nanoparticles enhances the bioactivity, antimicrobial effectiveness, and biocompatibility of zirconia, making it a viable candidate for dental restorative applications.

期刊介绍: Journal of Biomedical Materials Research – Part B: Applied Biomaterials is a highly interdisciplinary peer-reviewed journal serving the needs of biomaterials professionals who design, develop, produce and apply biomaterials and medical devices. It has the common focus of biomaterials applied to the human body and covers all disciplines where medical devices are used. Papers are published on biomaterials related to medical device development and manufacture, degradation in the body, nano- and biomimetic- biomaterials interactions, mechanics of biomaterials, implant retrieval and analysis, tissue-biomaterial surface interactions, wound healing, infection, drug delivery, standards and regulation of devices, animal and pre-clinical studies of biomaterials and medical devices, and tissue-biopolymer-material combination products. Manuscripts are published in one of six formats: • original research reports • short research and development reports • scientific reviews • current concepts articles • special reports • editorials Journal of Biomedical Materials Research – Part B: Applied Biomaterials is an official journal of the Society for Biomaterials, Japanese Society for Biomaterials, the Australasian Society for Biomaterials, and the Korean Society for Biomaterials. Manuscripts from all countries are invited but must be in English. Authors are not required to be members of the affiliated Societies, but members of these societies are encouraged to submit their work to the journal for consideration.
