statement of problem: surface disinfection is an important aspect of infection control in dentistry. a new generation of quaternary ammonium components (qacs) is gaining popularity as high-level disinfectants. two types of qac sprays, uniseptaquick and solarsept, are being widely used by iranian dentists. purpose: the aim of this study was to evaluate the clinical efficiency of unisepta quick a...

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 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 radiol...

PURPOSE The aim of present study was to investigate the effect of chemical agents on the clinical isolates in Madani Heart Hospital, Tabriz, Iran. METHODS The minimum bactericide concentration (MBC) of disinfectants including chlorhexidine (Fort), peracetic acid (Micro) and an alcohol based compound (Deconex) on selected bacteria at various dilutions were determined by the standard suspension...

Silver nanoparticles have proved to possess significant antibacterial properties. Nanosilver produced by electrochemical reduction stabilized by cellulose derivatives, has been evaluated by European standards (CEN TC 216) in order to find out whether they could be applied in food, industrial, domestic and institutional areas as a suitable disinfectant. Moreover, bactericidal activity of nanosil...

BACKGROUND Dentistry equipment are exposed to different types of pathogenic microorganisms. The aim of this study was to investigate the effect of spraying three different types of disinfectants on condensational silicones after 5 and 10 min. MATERIALS AND METHODS Totally, 66 circular samples of condensational silicone impression materials of 1 cm diameter and 2 mm thickness were contaminated...

Objectives: Dental impressions are among the potentially infectious items in dentistry. Dental impressions are invariably contaminated with saliva or blood. Such fluids may contain viral or bacterial pathogens including Bacteroides, Fusobacterium, Porphyromonas and Prevotella. The aim of this study was to assess the effects of three different types of disinfectants on alginate impression materi...

In orthodontics effective disinfection of pliers in short time is important. We aimed to evaluate the effectiveness of three disinfectant solutions (two quaternary ammonium compounds (Deconex, Micro10+) and one hydrogen peroxide disinfectant (Sanosil)) in orthodontic pliers’ disinfection. Nine Adams pliers were sterilized with autoclave. Pliers were contaminated with standard and hospital staph...
