摘要:
 目的：探讨口腔综合治疗台水路消毒中微酸性电解水的有效性及其安全性。方法：选取在湘雅口腔医院接受口腔综合治疗的82例患者，应用独立水源综合口腔治疗台，每晚灌入现生成的微酸性电解水，并在第2天9:00和11:00时，在三用枪出水口和牙科手机出水口对水样进行采集，对细菌菌落数进行有效记录。分别对有效氯含量为30~45、15~20、8~15 mg/L浓度下的消毒水质合格率和使用微酸性电解质水后的水质合格率进行分析。结果：有效氯含量分别为30~45、15~20、8~15 mg/L时，微酸性电解水持续消毒水质合格率分别为96.3%、96.3%、94.3%，但是停止使用微酸性电解质水后，综合治疗台出口水的合格率逐渐降低，由100%降为0。结论：在对患者进行口腔综合治疗过程中，应用各种浓度的微酸性电解水效果无显著差别，通过对患者安全性、消毒效果进行综合考虑，应选用浓度较低的有效氯微酸性电解水对口腔综合治疗台水路进行消毒。
Abstract:
 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.
