背景牙科护理专业人员暴露于来自患者口腔的含有多种病原微生物的气溶胶。牙科治疗过程中产生的生物气溶胶对牙科工作人员有潜在危害，目的：对两个牙科诊所门诊前和门诊期间细菌和真菌气溶胶进行定性和定量研究，并与对照组进行比较。使用口腔排出系统测量细菌和真菌气溶胶。对细菌和真菌进行了宏观和微观分析，并根据细菌和真菌的代谢特性，通过生化试验对细菌和真菌进行了鉴定。定量和定性评价表明，在处理过程中，空气中的细菌和真菌浓度显着增加。微生物群落主要包括革兰氏阳性微生物（葡萄球菌属和微球菌属），革兰氏阳性杆菌和那些创造内生孢子，以及非多孔细菌和霉菌（枝孢菌和青霉）。结论暴露于微生物鉴定是不是一个显着的职业危害牙科保健专业人员，但是，循证预防措施建议。
Background Dental care professionals are exposed to aerosols from the oral cavity of patients containing several pathogenic microorganisms. Bioaerosols generated during dental treatment are a potential hazard to dental staff, and there have been growing concerns about their role in transmission of various airborne infections and about reducing the risk of contamination.Aims To investigate qualitatively and quantitatively the bacterial and fungal aerosols before and during clinical sessions in two dental offices compared with controls.Methods An extra-oral evacuator system was used to measure bacterial and fungal aerosols. Macroscopic and microscopic analysis of bacterial species and fungal strains was performed and strains of bacteria and fungi were identified based on their metabolic properties using biochemical tests.Results Thirty-three bioaerosol samples were obtained. Quantitative and qualitative evaluation showed that during treatment, there is a significant increase in airborne concentration of bacteria and fungi. The microflora included mainly gram-positive organisms (Staphylococcus epiderrnidis and Micrococcus spp.), gram-positive rod-shaped bacteria and those creating endospores as well as non-porous bacteria and mould fungi (Cladosporium and Penicillium).Conclusions Exposure to the microorganisms identified is not a significant occupational hazard for dental care professionals; however, evidence-based prevention measures are recommended.
