牙科手术通常会产生气溶胶和飞溅物，这些气溶胶和飞溅物有可能传播SARS-CoV-2等病原体。现有的文献是有限的。开发一种稳健、可靠和有效的方法来评价牙科气溶胶和飞溅物的分布和持久性，包括临床程序的评价。将黄绿素引入到高速空气涡轮机、超声除垢器和三合一喷雾器的冲洗储液器中，并在人体模型上一式三份地进行程序。将滤纸置于直接环境中。同时评估了牙科吸引和辅助存在的影响。使用摄影图像分析和荧光分光光度分析对样品进行分析。计算描述性统计量和Pearson相关系数用于分析方法的比较。所有手术均产生气溶胶和飞溅物。最靠近污染源的地方污染最严重，最高可达1 - 1.5 m。在高速空气涡轮机的最大测量距离（4 m）处可检测到污染，最大相对荧光单位（RFU）为：0.5 m处46，091，1.0 m处3，541，4 m处1，695。空间分布不均匀，操作员对面的污染水平最高。在术后30分钟和60分钟检测到极低水平的污染（≤原始水平的0.1%）。在0.5 - 1.5 m处抽吸可将污染减少67 - 75%。人体模型和操作员受到严重污染。两种分析方法具有良好的相关性（r = 0.930，n = 244，P <0.001）。牙科手术有可能在距离源一定距离处沉积存款气溶胶和飞溅物，在我们的环境中30分钟即可有效清除。
Dental procedures often produce aerosol and splatter which have the potential to transmit pathogens such as SARS‐CoV‐2. The existing literature is limited. To develop a robust, reliable and valid methodology to evaluate distribution and persistence of dental aerosol and splatter, including the evaluation of clinical procedures. Fluorescein was introduced into the irrigation reservoirs of a high‐speed air‐turbine, ultrasonic scaler and 3‐in‐1 spray, and procedures were performed on a mannequin in triplicate. Filter papers were placed in the immediate environment. The impact of dental suction and assistant presence were also evaluated. Samples were analysed using photographic image analysis and spectrofluorometric analysis. Descriptive statistics were calculated and Pearson's correlation for comparison of analytic methods. All procedures were aerosol and splatter generating. Contamination was highest closest to the source, remaining high to 1‐1.5 m. Contamination was detectable at the maximum distance measured (4 m) for high‐speed air‐turbine with maximum relative fluorescence units (RFU) being: 46,091 at 0.5 m, 3,541 at 1.0 m and 1,695 at 4 m. There was uneven spatial distribution with highest levels of contamination opposite the operator. Very low levels of contamination (≤0.1% of original) were detected at 30 and 60 minutes post‐procedure. Suction reduced contamination by 67‐75% at 0.5‐1.5 m. Mannequin and operator were heavily contaminated. The two analytic methods showed good correlation (r = 0.930, n = 244, P < .001). Dental procedures have potential to deposit aerosol and splatter at some distance from the source, being effectively cleared by 30 minutes in our setting.
