INTRODUCTION Presence of surface defects in endodontic instruments can lead to unwanted complications such as instrument fracture and incomplete preparation of the canal. The current study was conducted to evaluate the effect of autoclave cycles on surface characteristics of S-File by scanning electron microscopy (SEM). METHODS AND MATERIALS In this experimental study, 17 brand new S-Files (#...

Today, due to the high prevalence of infectious diseases and the risk of infection transmission in dental clinics, the control of infectious agents is critically important in dentistry. Given the importance of proper autoclave performance in dental processes, the aim of this study was to evaluate the performance of autoclave devices in the sterilization process using biological methods in denta...

The U.S. Environmental Protection Agency conducted an experiment to evaluate the effectiveness of a commercial autoclave for treating simulated building decontamination residue (BDR). The BDR was intended to simulate porous materials removed from a building deliberately contaminated with biological agents such as Bacillus anthracis (anthrax) in a terrorist attack. The purpose of the tests was t...

as they were being used (see, for example, Bowie, 1955; Howie and Timbury, 1956; Scott, 1957; Magee and Oakes, 1958; Nuffield Trust Report, 1958; Medical Research Council Report, 1959; and Wells and Whitwell, 1960). From the same work and that of others (see Bowie, 1958a and b; Alder and Gillespie, 1957; Knox and Penikett, 1958; Penikett, Rowe, and Robson, 1958; Rice, 1958; 1960; Medical Resear...

The aim of this study was to determine the effect of autoclave polymerization on the transverse strength of denture base polymers. To this end, 30 rectangular test specimens were fabricated of two heat-polymerized denture base polymers. The test groups were: (I) control, i.e., conventional water bath to polymerize resins by heat at 100 degrees C for 30 minutes; (II) autoclave polymerization at ...

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...

Background: Although most of the physical and mechanical properties of denture base resin polymerized by the conventional heat polymerization have been studied, the effect of autoclave processing in these properties has not been fully determined. The aim of the present study is to investigate the effect of two different cycles of autoclave processing on the transverse strength, impact strength,...

A device using a steam injection funnel is described by means of which air can be driven quickly and surely from an autoclave load. It is simple and inexpensive, necessitates no changes in the working routine of a microbiology laboratory, and does not interfere with the operation of the autoclave in its normal mode.
