The larval therapy involves the intentional application of sterilized and alive dipterans larvae on nonhealing wounds with the purpose of cleaning out the necrotic tissue to facilitate the healing process. This study aimed to evaluate the sterilization process and survival of Chrysomya megacephala (Fabricius), Chrysomya putoria (Wiedemann) and Cochliomyia macellaria (Fabricius) (Diptera: Callip...

PURPOSE Numerous federal bodies and professional societies have produced guidelines and standards for the reprocessing of endoscopes, but few specifically address the reprocessing of cystoscopes. MATERIALS AND METHODS This document presents a summary of the current recommendations for reprocessing flexible cystoscopes, and highlights particular aspects of instrument reprocessing that are uniq...

Sterilization is defined as any process that effectively kills or eliminates almost all microorganisms like fungi, bacteria, viruses, spore forms. There are many different sterilization methods depending on the purpose of the sterilization and the material that will be sterilized. The choice of the sterilization method alters depending on materials and devices for giving no harm. These steriliz...

Interaction between implant surface and surrounding bone influences implant fixation. We attempted to improve the bone-implant interaction by 1) adding surface micro scale topography by acid etching, and 2) removing surface-adherent pro-inflammatory agents by plasma cleaning. Implant fixation was evaluated by implant osseointegration and biomechanical fixation.The study consisted of two paired ...

background: every year millions of dollars are expended to equip and maintain the hospital sterilization centers, and our country is not an exception of this matter. according to this, it is important to use more effective technologies and methods in health system in order to reach more effectiveness and saving in costs. this study was conducted with the aim of evaluating the technology of regi...

A container used in contact lens cleaning requires a Pt plating weight of 1.5 mg for H₂O₂ decomposition although Pt is an expensive material. Techniques that decrease the amount of Pt are therefore needed. In this study, Pt nanoparticles instead of Pt plating film were supported on a substrate of acrylonitrile-butadiene-styrene copolymer (ABS). This was achieved by the reduction of Pt ions in a...

AIMS In spite of increasing reuse of disposable catheters, there are few scientific data on potential viral transmission and infection after reuse. To determine the theoretical risk of virus transmission during reuse of catheters an in vitro study was performed using an RNA virus (echovirus-11) and a DNA virus (adenovirus-2). METHODS AND RESULTS After deliberate contamination of the catheters...

BACKGROUND In recent times, it has been proposed to classify endodontic files as single-use items due to a perceived inability to adequately clean the instruments. The purpose of the present study was to quantify the surface debris on files removed from the manufacturer's packaging, and after cleaning using an ultrasonic bath or a thermal disinfector. METHODS Stainless steel and rotary nickel...

Introduction. Endodontic instruments during root canal treatment come into contact with dentinal debris, irrigation solutions and medication agents, which reminants should be eliminated before sterilization. The aim of the study was to verify effectiveness different cleaning methods for removing calcium hydroxide paste residues from surfaces working parts hand instruments, as well propose an ef...
