本文调查研究了用气涡轮机切割牙面时,患者口腔内的细菌向周围污染的情况。方法用寒天培养基,从患者的口腔中分几处采取5分钟落下的细菌。其次调查术者眼镜片上附着的细菌,在培养基上经37℃48小时培养,计算出发育的细菌群落。结果从置在患者胸上的培养基,检出了许多的细菌群落。汽涡轮机的喷雾使口腔内的细菌在其周围飞溅,距离口腔越远,落下的细菌数越少。镜片上也检出了较多的细菌,表明给术者面部带来污染。本次实验只查了细菌类,并未直接调查病毒,但从结果来看,在治疗带有艾滋病病毒和肝炎病毒抗原的病人时,也能产生和本次实验同样的结果。乙肝病毒抗原
This paper investigates the contamination of the surrounding bacteria by bacteria in the patient's mouth when cutting the tooth surface with a gas turbine. Methods Cold medium was used to take 5 minutes of bacteria drop from the patient's mouth in several places. Second, investigators attached to the lens of bacteria, cultured in the medium at 37 ℃ for 48 hours to calculate the development of bacterial communities. Results From the media placed on the patient's chest, many bacterial communities were detected. Spraying of the steam turbine splashes the bacteria in the oral cavity around it, and the farther away from the oral cavity, the fewer bacteria drop down. The lens also detected more bacteria, indicating that the surgeon brought facial pollution. This experiment only checked bacteria, did not directly investigate the virus, but from the results, in the treatment of patients with HIV and hepatitis B virus antigen, can produce the same results with this experiment. Hepatitis B virus antigen
