Introduction: The purpose of this study was to compare the antibacterial effect of sodium hypochlorite gel and solution on Enterococcus faecalis (E. faecalis). The main purpose of a root canal treatment is to eliminate the bacteria and their products. Sodium hypochlorite solution has excellent antibacterial properties, but also some negative features. Materials and methods: Fifty six single...
Objectives: Dental impressions are among the potentially infectious items in dentistry. Dental impressions are invariably contaminated with saliva or blood. Such fluids may contain viral or bacterial pathogens including Bacteroides, Fusobacterium, Porphyromonas and Prevotella. The aim of this study was to assess the effects of three different types of disinfectants on alginate impression materi...
Introduction: Many vegetables are eaten raw which can lead to the prevalence of food borne diseases if not properly sanitized. The aim of this study was to compare the effect of chlorine, bleach and multioxidant solution in disinfection of edible vegetables. Materials and Methods: In this experimental study, 100 g of vegetables (lettuce, basil and mint) was disinfected by sodium hypochlorite, ...
Purpose: The aim of this study is to evaluate effectiveness of regularly used disinfectant solution in the disinfection of acrylic resin specimens contaminated with Candida albicans. Materials and methods: Thirty six acrylic resin specimens contaminated in vitro with 1.5×10 8 cfu/ml suspensions of microorganisms were immersed in disinfectants for 10 minutes, the control group was not submitted ...
Cladocerans are able to produce resting eggs inside a protective resistant capsule, the ephippium, that difficults the visualization of the resting eggs, because of the dark pigmentation. Therefore, before hatching experiments, methods to verify viable resting eggs in ephippia must be considered. This study aimed to evaluate the number of eggs per ephippium of Daphnia from two tropical aquatic ...
Background and Objectives: The aim of this study is the evaluation of bacterial contamination of Slit-lamps in Eye Centers of Farshchian Hospital and assessment of the current disinfectants on isolated bacteria from apparatuses. Methods: In a cross-sectional study, 400 samples were collected from different parts of Slit-lamps (200 samples before and 200 samples after disinfection). The samp...
Background: Sodium hypochlorite is found in bleaching agents used to cleaning dishes and bleach laundry. The ingestion of sodium hypochlorite causes acute corrosive esophagitis and gastritis. In establishing the diagnosis and therapeutic approach of acute corrosive poisonings, the upper endoscopy has great importance. The aim of this study was to determine predictive factors of gastrointestinal...
Optimised preparation and characterisation of lotus root starch oxidised with sodium hypochlorite (NaOCl) using response surface methodology | Jingshui Xu, Haiying Yang, Chaoyi Zhang, Chuyi Liu Agricultural Journals
Introduction & Objective: Chemical disinfectants should have minimum side effects on the denture base surface so they can reduce the amount of plaque accumulation. This study evaluates the effect of chemical disinfectants (glutaraldehyde 2% and sodium hypochlorite 1%, 2.5% and 5.25%) on surface roughness of heat cure acrylic denture. Materials & Methods: Fifty specimens were fabricated with...
Vegetables are an important source of nutrients, but they can host a large microbial population, particularly bacteria. Foodborne pathogens can contaminate raw vegetables at any stage of their production process with a potential for human infection. Appropriate washing can mitigate the risk of foodborne illness consequent to vegetable consumption by reducing pathogen levels, but few data are av...
