简要总结
Electrolysed water (EOW) is produced by the electrolysis of sodium chloride in an aqueous solution, producing chlorine gas at the anode and sodium hydroxide and hydrogen at the cathode. EOW is known to have antimicrobial effects against various microorganisms, including viruses, bacteria, spores and fungi. Its antimicrobial activity is generally attributed to its hypochloric acid content - a product of chlorine gas dissolved in water. Due to its biocompatibility, known uses of EOW include ocular disinfection, nasal irrigation and chronic cutaneous wound care. In the dental setting, it may be used as a mouthwash, disinfectant, irrigant, mouthwash or dental gel.
The aim of this study is to investigate the effect of a mouthwash containing neutral electrolyzed water on plaque accumulation (evaluated using a disclosing agent and an intraoral scanner), gingival inflammation, MMP-8 activity and the oral microbiome. In this double-blind, cross-over, 4-day experimental gingivitis model, each subject will participate in all three arms of the study. Each arm will last 4 days, during which the subjects will be asked to refrain from toothbrushing and the use of interdental cleaning devices. Instead, they will be instructed to rinse their oral cavities twice daily with either EOW, placebo or a positive control (chlorhexidine), according to a randomisation chart (each subject will receive a different mouthwash type in every arm of the study). The outcomes will be assessed at baseline and after 4 days. A washout period of at least 7 days will be implemented between each study arm.

研究组 & 干预措施
1
Based on a randomisation table, each participant will use either a mouthwash containing neutral electrolyzed water, placebo, or chlorhexidine digluconate twice a day instead of tooth brushing and flossing for 4 days. Each subject will receive each mouthwash type only once during the study period (he/she will receive a different mouthwash type in every arm of the study based on a randomisation table).
