摘　　要：目的探讨不同含漱液对超声洁治时口腔诊室空气中细菌数的影响以及患者对含漱液的接受度。方法选取56例超声洁治患者,按进入研究的顺序号随机分为4组,分别为过氧化氢组、氯己定组、次氯酸水组和对照组,每组14例,按分组于超声洁治前使用40 mL的1.50%过氧化氢、0.12%氯己定、100 mg/L次氯酸水和无菌水含漱1 min。在治疗前、治疗中及治疗后0和10 min用血琼脂平板自然沉降5 min采集空气样本,细菌培养并菌落总数计数,同时进行菌种鉴定。通过问卷调查患者对4种含漱液的接受度。结果经过氧化氢、氯己定和次氯酸水3种含漱液处理,治疗后0 min时空气中细菌菌落总数最大;治疗结束后10 min,3组空气中细菌菌落总数均能降到≤4 cfu/皿的要求;菌株以表皮葡萄球菌占比最高;次氯酸水患者接受度最高。结论超声洁治前100 mg/L次氯酸水含漱1 min能显著降低口腔诊室空气中细菌菌落总数,患者接受度较高。Objective To explore the effect of different mouthwashes on the bacterial count in the air of oral clinics during ultrasonic cleaning and the acceptance of mouthwashes by patients.Methods A total of 56 patients treated with ultrasonic cleaning were randomly divided into 4 groups according to the order of entry into the study,namely hydrogen peroxide group,chlorhexidine group,hypochloric acid water group,and control group,with 14 cases in each group.Patients were required to rinse with 40 mL of 1.50%hydrogen peroxide,0.12%chlorhexidine,100 mg/L hypochloric acid water,and sterile water for at least 1 min before ultrasonic cleaning.Before treatment,during treatment,and at 0 and 10 min after treatment,air samples were collected by natural sedimentation on a blood agar plate for 5 min,bacteria were cultured and the total number of colonies was counted,and bacterial species identification was performed.The patient's acceptance of the four mouthwashes was investigated through a questionnaire survey.Results After treatment with hydrogen peroxide,chlorhexidine,and hypochloric acid water,the total number of bacterial colonies in the air reached its maximum at 0 min.After 10 min of treatment,the total number of bacterial colonies in the air of all three groups decreased to 4 cfu/dish,with Staphylococcus pidermidis being the highest proportion.The hypochloric acid water received the highest acceptance.Conclusion Rinsing with 100 mg/L hypochloric acid water for 1 minute before ultrasonic cleaning can reduce the total number of bacterial colonies in the air of oral clinics,and has a higher acceptance.
