Potential for Spatial Laminar Airflow to Prevent Interdental-Chair Contamination in Multichair Dental Operatories

Introduction: The dental clinic has for a long time been considered as a risky place for infection dissemination. Due to aerosol generating procedures, the risk of cross-transmission in dental clinics has recently risen. Open dental clinics should undergo present-time reassessment concerning infecti...
