Abstract

Background: Concerning about the quality of room air has increased exponentially. Specially in dental clinics where diary practice is characterized by the important generation of aerosols.

Material and methods: An in vitro model was used in which samples were collected from the surfaces and room air of a dental clinic before and after the use of an OH˙ radical generator.

Results: A total of 1260 samples were collected for bacteriological analysis and 14 samples for the detection of SARS-CoV-2. Following OH˙ treatment, the tested surface samples showed a decrease in the number of colony forming units (CFUs) of 76.9% in TSA culture medium. The circulating room air samples in turn showed a decrease in CFUs of 66.7% in Sabouraud medium and 71.4% in Mannitol agar medium. No presence of SARS-CoV-2 was observed on the surface of the face shield.

Conclusions: The disinfectant technology based on the use of hydroxyl radicals (OH˙) is effective in reducing the presence of moulds and yeasts and Staphylococcus in the air, and in reducing total aerobic bacteria on the tested surfaces.

评价羟基自由基 (OH˙) 释放对牙科诊所空气和表面消毒的功效：一项体外研究。

背景介绍人们对室内空气质量的关注急剧增加。特别是在牙科诊所，因为牙科诊所的特点是会产生大量气溶胶：材料和方法：采用体外模型，在使用 OH˙自由基发生器前后从牙科诊所的表面和室内空气中采集样本：结果：共采集了 1260 份样本进行细菌分析，14 份样本进行 SARS-CoV-2 检测。经 OH˙处理后，被测表面样本在 TSA 培养基中的菌落形成单位（CFU）数量减少了 76.9%。室内循环空气样本在沙保鲁培养基中的菌落形成单位数减少了 66.7%，在甘露醇琼脂培养基中减少了 71.4%。在面罩表面没有观察到 SARS-CoV-2 的存在：结论：使用羟基自由基（OH˙）的消毒技术能有效减少空气中的霉菌、酵母菌和葡萄球菌，并减少测试表面的需氧细菌总数。
