The order of the intensiveness of antibacterial activity in wideness of spectrum of various bacterial species was eugenol group, carboxylate group, zinc phosphate group, copper group=silicate phosahate group, silicate group. The two cements in eugenol group were active on all the indicator strains. Carboxylate group inhibited preferably anaerobes. The others were active on several strains. The action of cements on the susceptible cells was found to be both bactericidal and bacteriostatic, in which eugenol group acted mainly bactericidally. This bactericidal effects were demonstrated also in the teeth experimentally infected. Silicate group exhibited no measurable antibacterial activity. The inhibitory activities were rather stable, they did not lose at least 6 weeks in a solution except for one cement sample. The inhibitory activities were detected in the both of powder components and liquid components of the cements and the activities in the former components were stronger than those of the latter components. Of the authentic reagents consists of cements, eugenol, rosin, zinc oxide, and zinc phosphate exhibited inhibitory activity against various bactrial species.}, pages = {200--207}, title = {Antibacterial Actions of Dental Cements}, volume = {5}, year = {1979} }
