statement of problem: rotary dental instruments (i-e. iow speed and high speed handpieces), due to infection spread high potentiality, should be sterilized between dental visits for each patient. when a high speed rotary instrument pauses at a high velocity, contaminated fluids like blood and saliva will be sucked into its tubes.purpose: the aim of this study was to compare the bactericidal eff...

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...

Background and aims: Widely application of rotary files for endo treatment would force us to obtain an accurate understanding about the characteristics drawbacks these instruments. Therefore in this study, effects immersion NiTi M2 file deconex sodium hypochlorite solution on cyclic fatigue resistance was investigated Material methods: In exprimental 45 NITI were divided three groups I) control...

Dear Editor, Despite major advances in dentistry and dental prostheses, complete removable dentures are still widely used for oral rehabilitation of edentulous people. Denture surfaces prepare a favorable environment for adherence and proliferation of oral endogenous microorganisms, which is a crucial first step in the initiation of biofilm formation, caused denture stomatitis. Candida species ...
