Objective The study aims to improve the antimicrobial and remineralization-promoting properties of mouthwash by synthesizing novel Ag/ZnO/Oyster Shells nanocomposites and evaluating their anti-caries properties and biosafety in vitro and in vivo. Methods The antimicrobial properties of the synthesized Ag/ZnO/Oyster Shells nanocomposites were examined by bacterial inhibition zone, minimum inhibitory concentration, minimum bactericidal concentration, fluorescence staining and scanning electron microscopy. The potential of the materials to promote remineralization of demineralized enamel was detected by scanning electron microscopy, surface microhardness and depth of hard tissue defects, and laser confocal electron microscopy analysis. The synthesized materials were then incorporated into mouthwash to prepare novel mouthwash and their effects on antimicrobial properties, remineralization-promoting properties were evaluated. Furthermore, an oral mucosal contact model was established to assess local irritation and systemic effects. Results The results showed that the novel Ag/ZnO/Oyster Shells nanocomposites possessed strong antimicrobial activity, remineralization-promoting ability and good biosafety, and the mouthwash containing Ag/ZnO/Oyster Shells possessed strong antimicrobial performance and remineralization-promoting ability, and showed no obvious abnormalities in local mucosal tissues, blood indices, and histopathology of the liver and kidneys in the oral exposure model of the SD rats. Conclusions These findings indicate that Ag/ZnO/Oyster shell incorporated into mouthwash has strong antimicrobial activity, good remineralization-promoting properties, and good biosafety in vivo experiments, and is therefore expected to be used in clinical applications.

“…[73][74][75] An Ag/Zn 2 O/CaCO 3 composite constructed using oyster shells as a solid catalytic support exhibited excellent performance at reducing 4-nitrophenol, with a conversion rate of 97.6% within 8 min. 76 Shells have good application prospects in the field of catalysis, but their catalytic applications are usually based on calcium oxide. The calcination transformation process consumes additional energy and generates exhaust gas emissions.…”

Shellfish aquaculture has developed rapidly, and the annual production of shell waste by‐products exceeds 10 million tons. The reutilization of shell waste is a severe problem in terms of environmental protection and the development of the circular economy. Due to its limited economic value, shell waste has generally been discarded or sent to landfill without any further processing and reutilization, thereby wasting resources and severely degrading the coastal ecosystem. This review summarizes recent research into the reutilization of shell waste, including applications in the fields of agriculture, construction, environmental protection, chemical production, food additives and biomaterials. Problems and strategies related to the reutilization of shell waste are analysed in order to provide technical support for the large‐scale and high value‐added utilization of shell waste.

“…Therefore, the ideal bone cement should have the ability to promote the osteogenic activity of osteoblasts while inhibiting bacterial growth. , Antimicrobial drugs can help address the challenges posed by drug-resistant bacterial infections . ZnO is an antimicrobial material that has been widely used and demonstrated excellent antibacterial effects. − Felice et al prepared a polycaprolactone/ZnO/HA scaffold and found that after doping with ZnO, the scaffold exhibited good antibacterial activity and promoted early cell mineralization induction by the scaffold at a high concentration of ZnO.…”

Calcium silicate (CS), a new and important bioceramic bone graft material, is prepared by using eggshells, which have a porous structure and are rich in calcium ions. Furthermore, the preparation of new CS materials using eggshells and diatomaceous earth minimizes their negative impact on the environment. In this study, we prepared CS materials using a high-temperature calcination method. The composition of the material was demonstrated by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) analysis. Scanning electron microscopy (SEM) analysis confirmed the porous structure of the CS material. We also introduced ZnO to prepare ZnO−CS with antibacterial properties and showed that ZnO−CS exhibits excellent antibacterial effects through in vitro antibacterial experiments. Subsequent in vitro mineralization experiments demonstrated that ZnO−CS promoted the formation of a hydroxyapatite layer. Furthermore, in vitro cytotoxicity experiments demonstrated that ZnO−CS had very good biosafety and promoted cell proliferation. These findings were confirmed through subsequent cell proliferation experiments. Our results indicate that the novel ZnO−CS is a promising candidate for bone tissue engineering.
