Background/aim: Acid-electrolyzed functional water (FW) is an efficient bactericide and gargling with FW might be an effective method of oral care. We investigated the possible use of FW as a mouth wash by an in vitro study.
Materials And Methods: The bactericidal effect of FW against different species of bacteria (Staphylococcus aureus, Streptococcus pneumonia, Pseudomonas aeruginosa, and Candida albicans) was evaluated using the numbers of colony-forming units (CFU). The experiment was conducted using PBS, LISTERINE, and ConCool F (undiluted, and the optimal concentration indicated). To investigate the bactericidal mechanism of FW, the activity of superoxide dismutase (SOD), an indicator of oxidative action, was measured in S. aureus. FW was diluted with purified water to concentrations of 10, 30, 50, and 70%. The numbers of CFU were measured for each concentration. XTT assays were performed using HSC-3 and HeLa cells, to examine the viability of the cells following treatment with FW. The same experiment was conducted with PBS, LISTERINE, and undiluted ConCool F.
Results: No bacteria treated with FW formed colonies. SOD activity peaked at a 50% concentration of FW and was more than twice that of the control. A significant decrease in the number of CFU was observed following 50% treatment. Since the peaks of the SOD activity and the starting concentrations of the bactericidal effects coincided, the bactericidal effect of FW might be related to its oxidative effects. Bacteria treated with FW had the same survival rate as the other mouth washes.
Conclusion: FW might be clinically applicable as a mouth wash.

Streptococcus mutans, a key cause of dental caries, is not treated by conventional toothpaste, brushing, flossing, or antiseptic mouthwashes. This necessitates the development of enriched toothpaste. Cyanobacteria-derived phycoerythrin (PE) has antioxidant and antibacterial properties.

Penicillium expansum is a phytopathogen causing postharvest disease of many fruits, which has led to enormous losses. Therefore, it is of great significance to take efficient methods to control this notorious phytopathogen. In this study, zinc, an essential trace element for human body, has been found to be able to effectively inhibit the P.

As zinc is important for the fertilization competency of sperms and oocytes, we investigated the effects of zinc chloride (ZnCl) supplementation during in vitro fertilization (IVF) on porcine oocyte fertilization and development. We evaluated the effects of ZnCl concentration (0, 1, 10, and 20 μg/mL) on the quality of frozen-thawed boar spermatozoa cultured for 5 h and on oocyte fertilization and embryo development after IVF. Spermatozoa from three different boars were additionally tested.

Purpose: To evaluate the effect of different decontamination protocols on the bonding strength of MDP-containing resin cement to saliva-contaminated zirconia ceramic.
Methods: 144 zirconia samples (12 mmx12 mmx1.2 mm) were prepared from 4Y-TZP and 6Y-TZP blocks, sandblasted with 50 μm Al₂O₃, and contaminated with artificial saliva.

Purpose: To evaluate the effect of whitening mouthwashes with different active ingredients on the color change (ΔE₀₀) of a stained resin composite.
Methods: A total of 70 resin composite samples (G-aenial Anterior) with dimensions of 8 х 2 mm were prepared. The samples were immersed in coffee for 14 days to simulate time-dependent color change, then randomly assigned into seven groups (n=10).
