The purpose of this study was to coat an antimicrobial material on denture base resin. The antimicrobial activity, physical properties, and cytotoxicity of specimens were evaluated coating on Paeonialactiflora
In order to evaluate the physical change, microhardness, color difference, and contact angle measurements were conducted. The OD (optical density) values of Streptococcus mutans and Candida albicans were obtained to confirm the antibacterial activity. In addition, the MTT method was used to evaluate the cytotoxicity of the coating extract.
The physical properties of the denture base resin coated with the extract changed. Compared with the uncoated specimens, the hardness improved and the contact angle reduced, indicating a hydrophilic surface. The color change could not be confirmed by the color difference measurement. The Paeonialactiflora extract showed antimicrobial activity 48 h after exposure to Streptococcus mutans and Candida albicans. The extract did not show cytotoxicity.
The antimicrobial activity of the denture base resin coated withPaeonialactiflora extracts was confirmed. In the future, various antibacterial substances from natural extracts should be developed.
