The effects of phenoxyethanol, chlorhexidine and a mixture of both on subgingival plaque
samples from 44 patients with chronic periodontitis were investigated in vitro. At a
concentration of 0.5 mg/ml, chlorhexidine inhibited the growth of all cultivable bacteria in all
44 samples while a comparable effect was achieved with phenoxyethanol only at a
concentration of 20 mg/ml. All cultivable bacteria in the samples were inhibited by a mixture
of the two agents containing 5 mg/ml of phenoxyethanol and 0.125 mg/ml of chlorhexidine ie …
