Bacterial aerosols in the dental clinic: a review

A number of sources of bacterial aerosols exist within and outside the dent al clinic. The concentration of bacterial aerosols and splatters appears to be highest during dental procedures, especially those generated by some pr ocedures such as ultrasonic scaling, or using a high speed drill. Several i nfectious diseases could be transmitted to staff and patients by airborne b acterial and other contaminants in the dental clinic. Air-conditioning and ventilation systems should be regularly maintained to reduce environmental contaminants and to prevent recirculation of bacterial aerosols. Pre-proced ural rinsing by patients with mouthwashes as well as vacuum and electrostat ic extraction of aerosols during dental procedures could also be employed. Dental staff should also consider appropriate immunisations and continue to use personal protective measures, which reduce contact with bacterial aero sols and splatters in the dental clinic.
