Sir,?With reference to the query on p. 297 of your May issue, the method used by me for sterilizing syringes Js described below:? I carry a few " Soloid " examethylenetetrainine (B. W. & Co.) and a spoon in my injection outfit. The needle !s boiled in the spoon over the burning soloid which gives out a good heat. The boiling water is also drawn into the syringe several times. I have given a goo...

LEVEL: INTERMEDIATE L ast month, Part 1 of this article discussed some proven applications of chlorine dioxide (CD) gas and solutions as cleaning/sterilizing agents for isolators, process vessels, filter membranes, water systems, hard surfaces, and cleanrooms. Potential applications were also described, including the production of sterilized water from USP-grade water; sanitization of chromatog...

A study was undertaken to evaluate different procedures to safely remove microorganisms, protein, and mammalian cells from materials and provide a suitable method for cleaning and assessing effectiveness of cleaning medical devices for reuse or for analysis of failure. Safety considerations for the personnel performing the cleaning or handling the device after cleaning are important issues. Pol...

NiTi instruments have a high risk of separation due to torsional or flexural fatigue (cyclic fatigue). Chemomechanical preparation, cleaning procedures, chemical disinfection and sterilization cause the corrosion of endodontic instruments that may weaken the fracture resistance of the instruments. Objective To assess the effects of NaOCl immersion and autoclave sterilization on the cyclic fatig...

Corrosive surgical instruments are routinely observed in central sterile services departments around the world. In addition to other risks, they can harbor microorganisms form of biofilms. Thus, this study aimed evaluate whether biofilms intentionally formed at corrosion points on removable by manual and automated cleaning followed sterilization. Laboratory experiments were performed where samp...

Biomaterials must be both sterile and free of contaminants prior to use, and this is particularly critical for the next generation of implants based on tissue engineering. With increasing complexity of tissue engineering scaffolds and multifunctional devices, there is a need for new approaches to decontamination, i.e. cleaning, disinfection, and sterilization. This work presents our recent resu...
