Dextranase-producing organisms in dental plaque from caries-free and caries-active naval recruits

Dental plaque samples from caries-free and caries-active naval recruits were assayed for the prevalence of dextranase-producing organisms. These organisms were found in the plaque of all of the subjects. Mean percentages of dextranase-producing organisms with respect to total colony count for the 2 groups of subjects were not significantly different.
