Evaluation of the effectiveness of decontamination of dental syringes

Abstract

Short autoclaving cycles, albeit at raised temperatures, may fail to inactivate the virus because of poor steam penetration, inadequate heat transfer and the accumulation of protective biofilm.

Reducing the risk of prion transmission in anaesthesia

“…Biofilm, an exopolysaccharide matrix containing bacteria, which also accumulates on airways [7] and other foreign surfaces in the body, could protect viruses. Duck hepatitis virus in biofilm on reused dental syringes was resistant to ultrasonic treatment, glutaraldehyde disinfection or short autoclaving cycles at 134 °C [8].…”

Isolation and Antimicrobial Resistance ofStaphylococcus aureusIsolates in a Dental Clinic Environment

“…Microbial contamination of light handles and 3-in-l syringes was also investigated by McColl et al 25 Adequate dental equipment decontamination is extremely important, to remove bacterial deposits caused by clinical procedures. 26 However, cleaning 3-in-l syringe buttons is quite difficult because of the protective covers that overlap the buttons.…”

Is hepatitis B-virucidal validation of biocides possible with the use of surrogates?
