PÉCORA2 1Faculty of Dentistry, Federal University of Goiás, Goiânia, GO, Brazil 2Faculty of Dentistry of Ribeirão Preto, University of São Paulo, Ribeirão Preto, SP, Brazil The choice of an irrigating solution for use in infected root canals requires previous knowledge of the microorganisms responsible for the infectious process as well as the properties of different irrigating solutions. Complex internal anatomy, host defenses and microorganism virulence are important factors in the treatment of teeth with asymptomatic apical periodontitis. Irrigating solutions must have expressive antimicrobial action and tissue dissolution capacity. Sodium hypochlorite is the most used irrigating solution in endodontics, because its mechanism of action causes biosynthetic alterations in cellular metabolism and phospholipid destruction, formation of chloramines that interfere in cellular metabolism, oxidative action with irreversible enzymatic inactivation in bacteria, and lipid and fatty acid degradation. The aim of this work is to discuss the mechanism of action of sodium hypochlorite based on its antimicrobial and physico-chemical properties.

  • Disinfection Session Objectives
    Disinfection Session Objectives • To introduce the principal disinfectants that may be used and highlight key advantages and disadvantages of each • To emphasise the use of chlorination for routine disinfection. • To describe the process of chlorination and discuss the concepts of breakpoint chlorination, chlorine demand and outline basic chlorine chemistry. • To discuss the types of chlorine available and how these may be used for routine disinfection. WHO SEMINAR PACK FOR DRINKING-WATER QUALITY Disinfection Introduction All water supplies should be disinfected. This is aimed both at inactivating remaining bacteria before distribution and providing a residual disinfectant to inactivate bacteria introduced by any subsequent ingress of contaminated water during storage or distribution. At present, the principal disinfectant used worldwide is chlorine, although alternatives are being increasingly investigated and process such as ozonation are becoming more common. Chlorine is generally the disinfectant of choice as it is reasonably efficient, cheap and easy to handle. In all but the smallest water treatment plants, chlorine is added to water as either in aqueous solution (calcium hypochlorite or sodium hypochlorite) or chlorine gas. Smaller supplies may use tablets of hypochlorite. Other disinfectants include ozone, ultraviolet light and iodine. These all have disadvantages. UV is not a particularly effective disinfectant and it is difficult to expose water for sufficient time for disinfection to be effective. Neither ozone or UV provide a residual disinfectant and therefore offer no protection against recontamination in distribution. To overcome this, in some water supplies booster ozonation stations are set up along the distribution network. Both iodine and ozone are carcinogenic. There are also significant health and safety concerns, for operators, regarding the generation and application of ozone and chlorine (especially in the gaseous form).

  • Sodium Hypochlorite
    SODIUM HYPOCHLORITE What is SODIUM HYPOCHLORITE? Sodium hypochlorite is a liquid with an odor of chlorine. Usually it is clear but some solutions are greenish to yellow in color. Other names for sodium hypochlorite include Clorox , bleach, liquid bleach, sodium oxychloride, Javex, antiformin, showchlon, Chlorox, B-K, Carrel-Dakin Solution, Chloros, Dakin’s Solution, hychlorite, Javelle Water, Mera Industries 2MOm≥B, Milton, modified Dakin’s Solution, Piochlor, and 13% active chlorine. Where can sodium hypochlorite be found and how is it used? Sodium hypochlorite is mainly used as a bleaching agent or disinfectant. A disinfectant kills bacteria that can carry diseases. It is found in consumer and commercial bleaches, cleaning solutions, and disinfectants for drinking water, wastewater and swimming pools. How can people be exposed to sodium hypochlorite? You could be exposed to sodium hypochlorite through: Breathing fumes while using products containing sodium hypochlorite. Drinking water from public drinking water supplies where these chemicals were added to kill bacteria. You could also be exposed by drinking sodium hypochlorite by accident. Touching sodium hypochlorite if gloves are not worn when using products containing it. Eye Contact by splashing sodium hypochlorite during use. People who work where sodium hypochlorite is used to bleach paper and textiles may have slightly higher levels of exposure in all of the above areas. How does sodium hypochlorite work and how can it affect my health? Sodium hypochlorite is a corrosive substance, meaning that it will eat away at materials it contacts. Accidental sodium hypochlorite poisoning can be deadly. Severe injuries can occur to the mouth, throat, esophagus and stomach.

  • Nitrogen, Ammonia, Colorimetry, Salicylate-Hypochlorite, Automated-Segmented Flow
    Nitrogen, ammonia, colorimetry, salicylate-hypochlorite, automated-segmented flow Parameters and Codes: Nitrogen, ammonia, dissolved, I-2522-90 (mg/L as N): 00608 Nitrogen, ammonia, total-in-bottom-material, I-6522-90 (mg/L as N): 00611 1. Application 1.1 This method is used to analyze samples of surface, domestic, and industrial water, and brines containing from 0.01 to 1.5 mg/L of ammonia-nitrogen. Concentrations greater than 1.50 mg/L must be diluted. This modified method was implemented in the National Water Quality Laboratory in March 1988. 1.2 This method also is used to determine concentrations of ammonia-nitrogen in samples of bottom material containing at least 0.2 mg/kg NH3-N. Prepared sample solutions containing more than 1.5 mg/L NH3-N need to be diluted. 1.3 Sodium ion is a good replacement for ammonium ion in the slow-exchange positions of soil minerals (Jackson, 1958). Bottom material is treated with an acidified sodium chloride solution, and the resulting mixture is allowed to settle and then decanted to obtain a clear supernatant solution for analysis. 2. Summary of method Ammonia reacts with salicylate and hypochlorite ions in the presence of ferricyanide ions to form the salicylic acid analog of indophenol blue (Reardon and others, 1966; Patton and Crouch, 1977; Harfmann and Crouch, 1989). The resulting color is directly proportional to the concentration of ammonia present. 3. Interferences 3.1 Sulfide interferes. Bromide and nitrite can interfere. Calcium and magnesium in highly alkaline waters (pH greater than 13.6) can exceed the ability of the tartrate to complex both ions.

  • COVID-19 Environmental Cleaning and Disinfectants for Clinic
    Coronavirus COVID-19 BC Centre for Disease Control | BC Ministry of Health Environmental Cleaning and Disinfectants for Health-Care and Clinic Settings Cleaning: the physical removal of visible soiling (e.g., dust, soil, blood, mucus). Cleaning removes, rather than kills, viruses and bacteria. It is done with water, detergents, and steady friction from cleaning cloth. Disinfection: the killing of viruses and bacteria. A disinfectant is only applied to objects; never on the human body. All visibly soiled surfaces should be cleaned before disinfection. Environmental cleaning for the COVID-19 virus is the same as for other common viruses. Cleaning products and disinfectants that are regularly used in hospitals and health-care settings are strong enough to deactivate coronaviruses and prevent their spread. Cleaning of visibly soiled surfaces followed by disinfection is recommended for the prevention of COVID-19 and other viral respiratory illnesses. Suggested cleaning and disinfecting frequencies for health-care and clinic settings: Type of surface Frequency 1. Shared equipment IN BETWEEN PATIENTS otoscopes, baby scales, tables and exam beds 2. Frequently-touched surfaces Examples: medical equipment, door knobs, light AT LEAST TWICE A DAY switches, telephones, keyboards, mice, pens, charts, cell phones, toys, bathrooms 3.

  • Guidelines for the Use of Sodium Hypochlorite As a Disinfectant for Biological Waste Version 1.0 Prepared By: Animal Research Safety Consultant, Dr
    GUIDELINES FOR USING SODIUM HYPOCHLORITE AS A DISINFECTANT FOR BIOLOGICAL WASTE INTRODUCTION Sodium hypochlorite, commonly known as bleach, is most frequently used as a disinfecting agent. It is a broad-spectrum disinfectant that is effective for the disinfection of viruses, bacteria, fungi, and mycobacterium. However, sodium hypochlorite is NOT effective in the disinfection of bacterial spores and prions. CONCENTRATION & CONTACT TIME The appropriate concentration of sodium hypochlorite for disinfecting general liquid biological waste is 5000 ppm, approximately 0.5%. Household bleach is 5 - 6 % sodium hypochlorite; therefore a 1:10 (v/v) dilution of bleach to liquid biological waste is appropriate. For biological waste containing a high organic load (e.g. blood, proteins, or lipids) the appropriate concentration of sodium hypochlorite is 10000ppm, approximately 1%, therefore a 1:5 (v/v) dilution of bleach to liquid biological waste is appropriate. Minimum Contact time: Surface disinfection - 1 min Liquid waste disinfection - 20 min Important Notes: Discount brands of bleach may have lower concentrations of sodium hypochlorite and "colour safe" bleach contains NO sodium hypochlorite (hydrogen peroxide), these products should NOT be used for the disinfection of biological waste. Sodium hypochlorite is known to be corrosive to metals, therefore, it important to wipe down metal surfaces with water or ethanol after treating them with a bleach solution. STABILITY & STORAGE Bleach should be stored between 2-8°C (50-70°F). According to Clorox, undiluted household bleach has a shelf life of six months to one year from the date of manufacture, after which bleach degrades at a rate of 20% each year until totally degraded to salt and water, and a 1:10 bleach solution has a shelf life of 24 hours.
