Kinetics of Molybdenum Disulfide Oxidation in Sodium Hypochlorite Solutions

Sodium Hypochlorite Solutions

hypochlorite (NaOCl) associated with a surfactant. Seventy single-rooted extracted human teeth were inoculated with Enterococcus faecalis, and incubated for 21 days (37 °C). The groups were distributed according to the irrigation solution used during root canal preparation: 5%, 2.5% and 1% NaOCl; 5%, 2.5% and 1% Hypoclean®, a solution containing a surfactant (cetrimide) associated with NaOCl. T...

Kinetics and Mechanism of Hypochlorite Oxidation - of Polyvinyl Alcohol

The kinetics of oxidation of polyvinyl alcohol, FH-17, with sodium hypochlorite has been studied. The effects of ~ buffer concentration, pH, initial oxidant concentration and temperature of reaction on the rate of reaction have been investigated. The experimental data indicate that the reaction is first order with respect to hypochlorite concentration. Additional data on change in the rate of r...

The shelf-life of sodium hypochlorite irrigating solutions.

BACKGROUND Sodium hypochlorite (bleach) solutions are widely used as irrigants in endodontics. Their tendency to deteriorate is worsened by environmental influences which could cause loss of available chlorine content. METHODS This study measured the loss of available chlorine concentration in a range of sodium hypochlorite solutions under conditions which mimic clinical usage and storage. Do...

Sodium Hypochlorite

Bactericidal and cytotoxic effects of sodium hypochlorite and sodium dichloroisocyanurate solutions in vitro.

The antimicrobial and cytotoxic effects of sodium hypochlorite (NaOCl) and sodium dichloroisocyanurate (NaDCC) were evaluated and compared in vitro. The minimal inhibitory concentration and minimal bactericidal concentration of NaOCl and NaDCC were tested for Streptococcus sobrinus, Streptococcus salivarius, Enterococcus faecalis, and Streptococcus mutans. The cytotoxic effect was assessed by u...
