DENTAL OPERATORY CONTAMINATION
Abstract
A microbiological sampling of instruments intended for use in the treatment of patients in a dental operatory was taken. Selected instruments routinely used were sterilized by means of steam under pressure, dry heat, or ethylene oxide gas. Half of these sterilized instruments were exchanged for instruments intended for use from the dental unit, tray, or from the dental cabinet. The instruments were incubated in trypticase soy agar aerobically at 37 deg C for 72 hours. Eighty percent of the instruments intended for use developed biological growth. Most of these instruments were presumed properly sterilized but became contaminated during storage or upon delivery to the operating area.
