background and aims. the exposure and processing of dental radiographs are not routinely associated with the spatter of blood or saliva; however, infection control is still an issue resulting from contaminated equipment, supplies, film packets or cassettes. this study aimed at comparing the efficacy of four commercially available disinfectants on microorganisms present on the equipment of radio...

background and aims. the most common method for alginate impression disinfection is spraying it by disinfecting agents, but some studies have shown that these impressions can be immersed, too. the aim of this study was to evaluate the dimensional stability of alginate impressions following disinfecting by spray and immersion methods. materials and methods. four common disinfecting agents (sodiu...

Introduction: The purpose of this study was to compare dimensional changes of two types of auto polymerizing acrylic resin patterns (APARPs) in three different storing environments. Methods: 60 acrylic post and core patterns were made of two types of Duralay acrylic resins (Aria dent, Iran and Reliance, Dental Mfg. Co, USA) using a canine model. Then coronal, apical diameter and coronoapical le...

Background and Aim: Different methods have been proposed for rapid disinfection of gutta-percha (GP) cones. This study aimed to assess the efficacy of low-pressure radiofrequency cold plasma (LRFCP) in disinfection of GP cones compared to three chemical disinfectants. Materials and Methods: Seventy GP cones were allocated to seven groups of 10 each. All samples were initially sterilized with e...

background and aims. several products have been marketed for disinfecting impression materials. the present study evaluated the effect of deconex, micro 10, alprocid and unisepta plus sprays on staphylococcus aureus and candida albicans transferred to alginate and polyvinylsiloxane impression materials. materials and methods. a total of 180 impressions of a maxillary model (90 alginate and 90 p...

abstract       background and aim: dimensional changes of the impression materials after disinfection is a serious problem in dentistry which could fail the treatment. the aim of this study is to determine the effect of three disinfectants:2% deconex,5.25% sodium hypochlorite and nanosil d2 ,on dimensional changes of bayer alginate.       materials and methods: this experimental study was condu...
