The solvent action of sodium hypochlorite on fixed and unfixed necrotic tissue.

This study was carried out to answer the questions concerning the percentage of sodium hypochlorite needed to dissolve necrotic tissue and parachlorophenol- or formaldehyde-fixed necrotic tissue and the effect of the combined use of sodium hypochlorite and hydrogen peroxide. The results of this investigation indicate that a 3 percent concentration of sodium hypochlorite is optimum for the production of an adequate solvent action on necrotic tissue. A combination of sodium hypochlorite with 3 percent hydrogen peroxide did not result in an increased solvent action; therefore, their simultaneous use is not recommended.
