摘要
目的测量口腔诊疗中模拟牙体预备使用手机时产生喷溅物的喷溅范围,以确定口腔诊室中牙科综合治疗台的卫生安全距离,设置屏障的合理位置及安全高度。方法选取某三级综合性医院口腔科诊室模拟口腔牙体预备,采用5%亚甲蓝溶液作为喷溅物染色指示剂,使用载玻片采集口腔诊疗过程中水平及垂直方向上的喷溅物,用普通光学显微镜观察确定喷溅范围。结果口腔牙体预备使用手机时,水平方向最远喷溅距离为1 600 mm,距操作诊疗约1 000 mm处的垂直方向喷溅高度达1 800 mm。结论无物理屏障的2台牙科综合治疗台间最佳安全距离应大于1 600 mm,两牙科综合治疗台间物理隔断最小高度应不低于1 800 mm。
Objective To measure the spattering range of spatter produced by dental handpiece used for simulating dental preparation in dental clinic,so as to determine the safe hygienic distance,reasonable location of barrier and safe height of dental unit.Methods Dental preparation was simulated in a dental clinic of a tertiary general hospital,5% methylene blue solution was used as indicator agent of spattering dyeing,horizontal and vertical spatter produced during dental diagnosis and treatment was collected with glass slides,spattering range was determined by common optical microscope observation.Results When dental handpiece used for simulating dental preparation,the farthest spattering distance in horizontal direction was 1600mm,vertical spattering height was up to 1800mm away from 1000mm of diagnosis and treatment manipulation.Conclusion The best safe distance between two dental units without physical barrier should be more than 1600mm,the minimum height of physical barrier between two dental units should be no less than 1800mm.
