- Abstract: Objective To investigate the performance and safety of slightly acidic electrolyzed water for the disinfection of dental unit waterlines (DUWL). Methods A total of 82 patients who underwent oral comprehensive treatment in Xiangya Stomatological Hospital were enrolled in the study. An integrated dental unit with independent water source was used for treatment. The newly generated slightly acidic electrolyzed water was applied for disinfection every night, and at 9:00 and 11:00 of the next day, the water samples were collected at the water outlet of 3-purpose syringe and dental handpiece for effectively recording the number of bacterial colonies. The qualified rate of disinfectant water and the qualified rate of water after disinfection using slightly acidic electrolyzed water were analyzed at the chlorine content of 30-45, 15-20 and 8-15 mg/L, respectively. Results When the chlorine content was 30-45, 15-20 and 8-15 mg/L, the qualified rate of water which was continuously disinfected with slightly acidic electrolyzed water was 96.3%, 96.3% and 94.3%, respectively. After stopping the use of slightly acidic electrolyzed water, the qualified rate of DUWL was gradually decreased from 100% to 0. Conclusion During the oral comprehensive treatment of patients, there is no significant difference in the disinfection effect among various concentrations of slightly acidic electrolyzed water. Considering the safety and disinfection effect, the low concentration of chlorine-containing slightly acidic electrolyzed water should be selected for the disinfection of DUWL.
