| Performing a through disinfection of any dental prostheses before it is transferred to a dental laboratory is the key to prevention of accidental infection of the dentist and dental laboratory personal. This means that a dental prostheses must not only be disinfected on the surfaces but also on the interior material. 12 samples of acrylic plates of 48 mm × 25 mm × 3 mm in dimension were prepared by water bath curing method. The samples were immersed in broth culture of four identified bacteria for 24 hours. Later on, all the specimens were grouped and immersed in three or different disinfectant solution which were lodophor, chlorhexidine, and sodium hypochlorite. They were prepared and used in accordance with manufacturer's recommendations. The control group was normal saline solution. Cultures were made from smooth, rough and interior surface of acrylic samples. Any bacterial growth when existed, was identified by microbiological test. In this study the results demonstrated that bacteria can penetrate acrylic resin plates cured by this technique. However, the only effective disinfectant was 0.525% solution of sodium hypochlorite 10 minute immersion. It disinfect the exterior as well as the interior surfaces of acrylic resin plates of 3 mm thickness | ||
