Tooth preparation dust, an indispensable part of dental treatment, contains bacteria and viruses. In order to examine environmental pollution in the dental clinic during tooth preparation, we monitored microorganism spread by counting colony forming units (CFU) with the "Andersen Microbe Sampler." This test was conducted in a "Clean Booth." Mitis-salivarius medium was used to count the oral-streptococcus species. The ability of the "Extra-Oral Vacuum Aspirator (EOVA)" to effectively eliminate contamination was also tested, and the EOVA was found to reduce the spread of oral-streptococci, significantly. The EOVA was therefore viewed as an effective method for reducing air pollution in the dental clinic, and should be used when treating patients with certain infectious diseases.
牙体预备粉尘是牙科治疗中不可或缺的一部分，其中含有细菌和病毒。为了检测牙体预备过程中牙科诊所的环境污染情况，我们使用“安德森微生物采样器”通过计数菌落形成单位（CFU）来监测微生物传播。该测试在“清洁工作间”进行。使用轻唾培养基来计数口腔链球菌种类。还测试了“口外真空抽吸器（EOVA）”有效消除污染的能力，发现EOVA能显著减少口腔链球菌的传播。因此，EOVA被视为减少牙科诊所空气污染的有效方法，在治疗某些传染病患者时应使用。
