| Abstract | Objectives: To evaluate the mechanical ventilation rates of dental treatment rooms and assess the effectiveness of aerosol removal by mechanical ventilation and a portable air cleaner (PAC) with a high-efficiency particulate air (HEPA) filter. Methods: Volumetric airflow were measured to assess air change rate per hour by ventilation (ACH Results: ACH Conclusions: Aerosol accumulation may occur in dental treatment rooms with poor ventilation. Addition of PAC with a HEPA filter significantly reduced aerosol accumulation and accelerated aerosol removal. Clinical significance: Addition of PAC with a HEPA filter improves aerosol removal in rooms with low ventilation rates. |
