Studies on Dental Aerobiology: II. Microbial Splatter Discharged from the Oral Cavity of Dental Patients

Abstract

The distribution and bacterial content of splatter particles emanating from a patient's mouth during dental procedures was studied in a controlled environment operatory. Levels of contamination far exceeding those produced by common oral activities were observed. Suction and preoperative oral hygiene procedures are not effective in reducing contamination from bacterial splatters, and the modification of certain procedures and the use of protective shields or glasses is advised.
