The effects of temperature, concentration, and tissue type on the solvent ability of sodium hypochlorite

Abstract

Fresh, fixed, and necrotic rat connective tissue specimens were treated with 2.6% or 5.25% concentrations of sodium hypochlorite. Each solution was heated to one of two temperatures, 73.2 F and 140F. The effectiveness of the concentration temperature combination was measured as to the speed and the completeness of tissue dissolution. The results showed that regardless of concentration, sodium hypochlorite solution heated to 140 F was more effective than the same solutions at 73.2 F. Furthermore, 5.25% concentrations of sodium hypochlorite solutions were more effective than those at 2.6% at either temperature.
