旋转牙科器械会产生大气气溶胶，这些气溶胶会沉积在各种表面上，包括牙医的头部。本研究的目的是定量评估牙科医生头部的细菌污染，并评估是否受到使用橡胶坝的影响。高年级牙科学生（n = 52）被要求戴高压灭菌头巾作为收集媒体，同时进行修复性牙科治疗，橡胶坝和没有。手术30分钟后，从每个头巾上取4个点进行细菌培养。通过计数菌落形成单位来定量细菌污染。无论收集点，使用橡胶坝与更多的细菌菌落形成单位比不使用橡胶坝（P = 0.009）。尽管其临床价值，橡胶坝似乎导致牙医头部的各个区域上的气溶胶水平显著更高，这要求牙医用合适的防护服覆盖他们的头部。(C)2016年沙特国王本阿卜杜勒阿齐兹健康科学大学。出版社：Elsevier Limited All rights reserved.
Rotatory dental instruments generate atmospheric aerosols that settle on various surfaces, including the dentist's head. The aim of this study was to quantitatively assess bacterial contamination of the dentist's head and to evaluate whether it is affected by using a rubber dam. Senior dental students (n = 52) were asked to wear autoclaved headscarves as collection media while performing restorative dental treatment with and without a rubber dam. Four points from each headscarf were swabbed for bacterial culture after 30 min of operative work. Bacterial contamination was quantified by counting the colony-forming units. Regardless of the collection point, using a rubber dam was associated with more bacterial colony-forming units than not using a rubber dam (P = 0.009). Despite its clinical value, the rubber dam seems to result in significantly higher aerosol levels on various areas of the dentist's head, requiring that dentists cover their heads with suitable protective wear.
