Background: There has been an increasing demand for more sanitary bidet seats in many healthcare settings because of concerns regarding potential contamination of the spray nozzles of warm-water bidet toilet seats. This contamination is thought to possibly serve as a reservoir for horizontal transmission of drug-resistant bacteria.
Aim: This study was performed to determine the optimal decontamination conditions and verify the effectiveness of these decontamination conditions.
Methods: An test of rinsing with neutral electrolysed water was performed using seven strains of The decontamination effect of the neutral electrolysed water was verified by a field test involving an analysis of the number of bacteria isolated from samples collected from the spray nozzles and the sprayed water from 10 toilet seats at the internal medicine ward of Juntendo University Hospital.
Findings: The test results showed that the decontamination effect of neutral electrolysed water tended to be higher with higher free chlorine concentrations in the nozzle-cleaning water and shorter intervals of rinsing. The field test involving the hospital ward toilets showed that routine physical cleaning was satisfactorily effective.
Conclusion: The study results suggest that the risk of horizontal transmission of drug-resistant bacteria via the use of bidet toilet seats in hospitals can be reduced by general cleaning and appropriate control of the free chlorine concentration in the nozzle-cleaning water.

Context: Some kinds of electrolysed water have been reported to exhibit antioxidant and bactericidal activity. However, studies on the effect of electrolysed hydrogen-rich water (EHW) with a neutral pH on cariogenic bacteria are limited.
Aim: This study aimed to evaluate the feasibility of using EHW as a mouthwash by examining its various effects on cariogenic bacteria.

Objectives: The objective of this scoping review was to map evidence of electrolysed oxidising water (EOW) as a biocide for dental applications of relevance to older people and identify research gaps.
Background: EOW is an emerging, "green," and cost-effective biocide. There are no reviews on the landscape of EOW research as either an antiseptic or disinfectant in dental healthcare or its suitability for the oral healthcare of older people.

Article Synopsis
- Denture stomatitis is common in older adults, posing health risks, and this study evaluates the effectiveness of ready-to-use neutral-pH Electrolysed Oxidizing Water (EOW) as a disinfectant for dentures, particularly against Candida albicans biofilms.
- The research involved measuring various properties of EOW over time and testing its antimicrobial activity, showing that EOW maintains its effectiveness even after five months of storage at cool or room temperatures.
- Results indicated that EOW significantly reduces bacterial and fungal colonies and biofilm activity, supporting its use for denture disinfection in clinical settings.
