摘要
Abstract
Objective:To simulate and assess the deposition of aerosols following prolonged ultrasonic scaling proce-dures.Methods:To mimic the aerosols released from a patient's oral cavity during treatment,Serratia marcescens(S.marcescens)and a BGI aerosol generator were utilized.Nutrient agar plates were employed to sample the surfaces that were prone to human contact within the clinic.In parallel,an Andersen-6 impingement air microorganism sampler was used to capture aerosol particles suspended in the air,ensuring a comprehensive assessment of their deposition in the clinic.Results:Colony deposition was detected at all sampling sites.The highest deposition of aerosol particles were found on the tray of dent-al chair equipment,the table above the patient's head,and the table where the computer was placed.It was also observed that the colony deposition numbers on the tray of the dental chair equipment and the lid of the medical garbage exceeded the aver-age level observed throughout the clinic.Conclusion:The deposition of biological aerosols is a common occurrence in diag-nostic and therapeutic environments.Therefore,it is recommended that surfaces such as the tray of dental chair equipment un-dergo disinfection after prolonged periods of use.关键词
