— The presence of bacteria in young dentin exposed to the oral environment has been assessed using the Brown and Brenn staining technique on demineralized sections of 45 premolars. A bacterial plaque always covered surfaces which had been exposed to the oral environment for some time. Only slight penetration of bacteria into the dentin was found, and the bacteria never reached the pulp. No bacteria could be demonstrated on the exposed surfaces or in the subjacent dentin in teeth which had been extracted immediately after the exposure of the dentin.
