摘　　要：目的:评价一种新型防喷溅面罩在口腔临床治疗中降低诊室内气溶胶浓度的效果。方法:首先分析不同类型口腔喷溅操作下(高速涡轮机下的窝洞制备、牙体预备、邻面去釉及超声治疗仪下的龈下刮治)气溶胶的分布特征;之后在仿真头模上模拟进行离体牙牙体预备,根据是否使用防喷溅面罩分为实验组与对照组,分别于喷溅操作治疗前、中、后多个时间点对室内气溶胶浓度进行采样,并记录及统计数据,评估使用新型防喷溅面罩降低口腔诊室内气溶胶效果。结果:不同类型口腔喷溅操作后诊室内气溶胶浓度均升高(P<0.05);其中,牙体预备喷溅操作后诊室内气溶胶浓度升高最明显(P<0.05)。因此,在仿真头模上模拟进行离体牙牙体预备,比较使用防喷溅面罩前后诊室内气溶胶的变化,结果显示使用面罩后诊室内气溶胶减少明显(P<0.05)。结论:不同类型的口腔喷溅操作均会产生高浓度气溶胶;使用这种新型患者佩戴的防喷溅面罩能有效降低口腔临床喷溅操作治疗过程中诊室环境内的气溶胶浓度,对于防止呼吸道传染病传播具有现实意义。Objective:To evaluate the effect of a new anti-splash mask on preventing aerosol pollution in dental clinics.Methods:The aerosol distribution characteristics in different types of splash operations were analyzed in dental clinics at first.Different splash operations were composed of cavity preparation,tooth preparation,interproximal enamel reduction,and supragingival scaling.Then tooth preparation on isolated teeth was simulated in dental phantom head.According to whether to use the anti-splash mask,experiments were divided into the experimental group and the control group.The droplets of aerosol at multiple time points were sampled before,during,and after dental procedures.The effectiveness of preventing aerosol pollution by the novel anti-splash mask was analyzed.Results:The aerosol concentrations caused by diverse splash operations in the clinics increased respectively(P<0.05).The aerosol concentration resulting from tooth preparation was the highest(P<0.05).To simulate dental treatment,tooth preparation was performed on isolated teeth in dental phantom head.It was found that the aerosol concentration was significantly decreased when using anti-splash masks(P<0.05).Conclusion:Diverse dental splash procedures initiated a large amount of aerosol respectively.The use of novel anti-splash mask in the process of dental diagnosis and treatment can reduce the aerosol concentration in dental clinics,which have a positive effect on preventing the spread of COVID-19.
