Materials and Methods: Class V cavities were prepared on 20 extracted mandibular molars. The cavities in the experimental groups were pre-treated with a scrub of cavity disinfectants followed by application of bonding agent. Preparations without cavity disinfectants served as control. After the cavities were restored with resin composite (G-Aenial Universal Flo), the specimens were subjected to...

We recently established a novel disease entity presented as progressive respiratory failure associated with the inhalation of humidifier disinfectants. In April 2011, we encountered a series of peripartum patients with complaints of respiratory distress of unknown etiology, which was an uncommon phenomenon. Accordingly, we created a multidisciplinary team comprising intensivists, radiologists, ...

Antiseptics and disinfectants are extensively used in hospitals and other health care settings for a variety of topical and hard-surface applications. A wide variety of active chemical agents (biocides) are found in these products, many of which have been used for hundreds of years, including alcohols, phenols, iodine, and chlorine. Most of these active agents demonstrate broad-spectrum antimic...

The antibacterial effect of 11 new commercially manufactured disinfectants on clinical isolates of Salmonella typhimurium DT104, Serratia marcescens and Pseudomonas aeruginosa was studied. The substances tested represented six pure quaternary ammonium substances (QAS) and five QAS combined with other ingredients. The antibacterial efficacy was characterized by influencing the growth of bacteria...

Biofilm is a multicellular layer of adherent bacteria surrounded by organic polymer matrix. The development of biofilms in food processing environments is a potential source of hazard for food safety and quality [1]. Food contact surfaces are commonly disinfected with different chemical compounds. However, corrosion and toxicity limit the use of these commercial disinfectants [2]. The risk will...

Most critical instruments are not designed for heat sterilization and autoclaving. These items are usually treated with chemical agents such as peracetic acid(PAA), glutaraldehyde (GA) and ortho-phthalaldehyde (OPA). MTT assay is often used to evaluate the in vitro cytotoxicity of these chemical agents. In this study, disinfectants were allowed to come in direct contact with cells. Their cytoto...
