Abstract
Polyvinylpyroridone-iodine, povidone-iodine, has widely been used as an antiseptic for the skin and mucous membrane. A similar antiseptic, β-cyclodextrine-iodine which contains β-cyclodextrine instead of polyvinylpyroridone as the stabilizer, was tested for its antimicrobial effect in this experiment. In the study reported herein the antimicrobial efficiency of β-cyclodextrine-iodine was adequate even in dilutions up to 80 of the original solution of the antiseptic to kill all of 20 strains (13 species) of microorganisms including Staphylcccccus, Streptococcus and oral bacteria used in this experiment within 30 seconds. The bactericidal effect of β-cyclodextrine-iodine was comparable to or more than that of povidone-iodine, and the result indicated that β-cyclodextrine-iodine is a usefull disinfectant for the skin and mucous membrane.
