AIM To demonstrate the clinical feasibility of autoclaving certain silicone impression materials in order to avoid potential cross-contamination during handling, transport, and subsequent processing. BACKGROUND Semicritical devices are recommended to be treated at least with high-level disinfectants or actually steam sterilized at 134°C. To date dental impressions have been disinfected rather...

BACKGROUND With the global rise in the number of people infected with hepatitis B and C and HIV viruses, cross infection has become of paramount concern to dental health care workers and their patients. The objective of this study was to assess the infection control practice in the private dental sector in Riyadh, Saudi Arabia. SUBJECTS AND METHODS The study was conducted through a cross-sect...

This study investigated (1) the susceptibility of Bacillus anthracis (Ames strain), Bacillus subtilis (ATCC 19659), and Clostridium sporogenes (ATCC 3584) spores to commercially available peracetic acid (PAA)- and glutaraldehyde (GA)-based disinfectants, (2) the effects that heat-shocking spores after treatment with these disinfectants has on spore recovery, and (3) the timing of heat-shocking ...

With the development of minimally invasive tooth extraction, the incidence rate of iatrogenic cross infection is increasing. Hence, the present study was carried out in order to a) develop a new, feasible disinfection strategy to be used in high-speed turbine and 3-function sprayer water systems and b) assess the clinical significance of newly developed disinfection strategy. A total of 178 pat...

OBJECTIVES To evaluate the effectiveness of point of use water treatment with flocculent-disinfectant on reducing diarrhoea and the additional benefit of promoting hand washing with soap. METHODS The study was conducted in squatter settlements of Karachi, Pakistan, where diarrhoea is a leading cause of childhood death. Interventions were randomly assigned to 47 neighbourhoods. Households in 1...

BACKGROUND Central line-associated bloodstream infections (CLABSIs) result in increased length of stay, cost, and patient morbidity and mortality. One CLABSI prevention method is disinfection of intravenous access points. The literature suggests that placing disinfectant caps over needleless connectors decreases CLABSI risk. METHODS A quasi-experimental intervention study was conducted in a >...

Formalin is a hazardous chemical that needs careful handling and special storage. It generally used in dentistry because of its disinfectant fixative properties. Negligence on part the dental professionals by accidentally injecting formalin rather than original anesthetic can lead to internal tissue damage also may induce life threatening situation. The general practice storing bottles being su...
